Airworthiness Directives; General Electric Company GE90-76B; GE90-77B; GE90-85B; GE90-90B; and GE90-94B Turbofan Engines AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require initial and repetitive fluorescent penetrant inspections (FPIs) and eddy current inspections (ECIs) of the high-pressure compressor rotor (HPCR) 8-10 stage spool, part numbers (P/Ns) 1844M90G01 and 1844M90G02, for cracks between the 9-10 stages, at each piece-part exposure. This proposed AD was prompted by cracks discovered on one HPCR 8-10 spool between the 9-10 stages in the weld joint. We are proposing this AD to prevent failure of the HPCR 8-10 stage spool, uncontained engine failure, and damage to the airplane. DATES: We must receive comments on this proposed AD by February 7, 2011.

[Docket No. FAA-2008-0847; Directorate Identifier 2008-NM-056-AD] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Model 777-200, -200LR, -300, and -300ER Series Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: We are revising an earlier proposed airworthiness directive (AD) for certain Model 777-200, -200LR, -300, and -300ER series airplanes. The original NPRM would have required doing an inspection to identify the part number of the motor operated valve (MOV) actuators of the main and center fuel tanks; replacing certain MOV actuators with new MOV actuators; and measuring the electrical resistance of the bond from the adapter plate to the airplane structure, and doing corrective actions if necessary. The original NPRM also would have required revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This action revises the original NPRM by adding airplanes to the applicability. This action also revises the original NPRM by removing the requirement for revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness. We are proposing this supplemental NPRM to prevent electrical current from flowing through an MOV actuator into a fuel tank, which could create a potential ignition source inside the fuel tank. This condition, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES: We must receive comments on this supplemental NPRM by January 18, 2011.

ACTION: Notice of proposed rulemaking (NPRM).

----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for all Model MD-90-30 airplanes. This proposed AD would require repetitive inspections for cracking of the left and right upper center skin panels of the horizontal stabilizer, and corrective action if necessary. This proposed AD was prompted by a report of a crack found in the upper skin panel at the aft inboard corner of a right horizontal stabilizer. We are proposing this AD to detect and correct cracks in the horizontal stabilizer upper center skin panel. Uncorrected cracks might ultimately lead to the loss of overall structural integrity of the horizontal stabilizer. DATES: We must receive comments on this proposed AD by February 7, 2011.

[Federal Register Volume 75, Number 248 (Tuesday, December 28, 2010)][Pages 81409-81412] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2010-0437; Directorate Identifier 2009-NM-130-AD; Amendment 39-16539; AD 2010-25-06] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Model 737-200, -300, -400, and -500 Series Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Model 737-200, -300, -400, and -500 series airplanes. This AD requires repetitive inspections for cracking of certain fuselage frames and stub beams, and corrective actions if necessary. This AD also provides for an optional repair, which would terminate the repetitive inspections. For airplanes on which a certain repair is done, this AD also requires repetitive inspections for cracking of certain fuselage frames and stub beams, and corrective actions if necessary. This AD results from reports of the detection of fatigue cracks at certain frame sections, in addition to stub beam cracking, caused by high flight cycle stresses from both pressurization and maneuver loads. We are issuing this AD to detect and correct fatigue cracking of certain fuselage frames and stub beams and possiblesevered frames, which could result in reduced structural integrity of the frames. This reduced structural integrity can increase loading in the fuselage skin, which will accelerate skin crack growth and could result in rapid decompression of the fuselage. DATES: This AD is effective February 1, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of February 1, 2011.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD requires inspections for scribe lines in the fuselage skin at lap joints, the splice strap at certain butt joints, the skin or doubler at certain approved repair doublers, and the skin at decal locations; and related investigative and corrective actions if necessary. This AD results from reports of scribe line damage found adjacent to the skin lap joints, decals, and wing-to-body fairings. We are issuing this AD to detect and correct scribe lines, which can develop into fatigue cracks in the skin. Undetected fatigue cracks can grow and cause sudden decompression of the airplane. DATES: This AD is effective February 1, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of February 1, 2011.

----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above that are equipped with Thielert Aircraft Engine GmbH (TAE) Engine Model TAE-125-01 installed per Supplemental Type Certificate (STC) No. SA03303AT. This AD requires installing a full authority digital engine control (FADEC) backup battery, replacing the supplement pilot's operating handbook and FAA approved airplane flight manual, and revising the limitations section of the supplement airplane maintenance manual. This AD was prompted by an incident where an airplane experienced an in-flight engine shutdown caused by a momentary loss of electrical power to the FADEC. We are issuing this AD to prevent interruption of electrical power to the FADEC, which could result in an uncommanded engine shutdown. This failure could lead to a loss of engine power. DATES: This AD is effective February 1, 2011. The Director of the Federal Register approved the incorporation by reference of certain publication listed in the AD as of February 1, 2011.

ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: This amendment supersedes an existing emergency airworthiness directive (EAD) for the specified Sikorsky model helicopters. The EAD requires inspecting the LITEF Attitude Heading and Reference System (AHRS) unit of the navigation system to determine if it is at a Mod Status ``18.'' If either AHRS unit is at Mod Status ``18,'' the EAD requires installing placards on the instrument panel to prohibit single pilot instrument flight rule (IFR) and single pilot night flight and reducing airspeeds to 120 knots indicated airspeed (KIAS) if both autopilots uncouple during instrument meteorological conditions (IMC) or night flight. The EAD also requires inserting minimum crew and airspeed limitations into the Limitations section of the applicable Rotorcraft Flight Manual (RFM) to limit the minimumflight crew to 2 pilots for night flight and IFR flight and to reduce airspeed to 120 KIAS if both autopilots uncouple during IMC or night flight. This amendment contains the same requirements but draws the appropriate distinctions between IFR and IMC as used in the intended operating limitations. Also, unlike the EAD, this AD states the airspeed must be reduced to 120 KIAS if both autopilots uncouple during IMC or night flight. Further, we are removing the limitation contained in the Active Temporary Revisions relating to pilots keeping their hands and feet near the flight controls. This AD was prompted by the need to supersede the EAD to state the distinction between IFR and IMC as used in the operating limitations and to reduce the airspeed to 120 KIAS if both autopilots uncouple during IMC or night flight. The actions specified by this AD are intended to implement operating limitations based on an anomaly in the AHRS related to the 26 volt AC inverter that could result in a decoupling of both autopilots and to prevent loss of control of the helicopter during IMC and during night flight. DATES: Effective January 12, 2011. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of January 12, 2011. We must receive comments on this AD by February 28, 2011.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Model 747-200C, -200F, -400, -400D, and -400F series airplanes. That AD currently requires repetitive inspections for cracks in the overlapping (upper) skin of the upper fastener row of the lap joints of the fuselage skin in sections 41, 42, and 46; and related investigative and corrective actions, if necessary. This new AD expands the inspection area in the existing AD, and adds a modification of certain lap joints and certain post-repair inspections of the lap joints. Accomplishing the modification would end the repetitive inspections required by the existing AD for the length of lap joint that is modified. This AD results from a structural review of affected skin lap joints for widespread fatigue damage. We are issuing this AD to prevent fatigue cracking in certain lap joints, which could result in rapid depressurization of the airplane. DATES: This AD becomes effective February 1, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of February 1, 2011.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive inspections for cracking in the body skin around the aft corners of the nose wheel well; for certain airplanes, repetitive inspections for cracking in the skin splice plate at the aft corners of the nose wheel well; and related investigative and corrective actions if necessary. This AD also requires repetitive post-modification inspections for cracking in the body skin and the skin splice plate; for certain airplanes, an inspection for steel cross-shaped doublers on the larger aluminum doublers; and corrective action if necessary. This AD also requires repetitive surface high frequency eddy current (HFEC) inspections of a certain bulkhead outer chord, skin splice plate, and outer chord radius filler for cracking; repetitive detailed inspections for cracking of the bulkhead frame web and body skin; and corrective actions if necessary. This AD provides for optional terminating action for certain repetitive inspections. This AD was prompted by reports of cracking of the fuselage skin and adjacent internal skin splice plate at the left and right nose wheel well aft corners, and the outer chord of the body station (BS) 400 bulkhead. We are issuing this AD to detect and correct cracking of the fuselage skin or splice plate, which, together with cracking of the bulkhead outer chord, could result in large skin cracks and subsequent in-flight rapid decompression of the airplane.

This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: A manufacturing quality non-conformity has been identified that resulted in the under-crimping of ring tags on a batch of In-tank Fuel Harnesses. The affected ring tags are used to join individual electrical wires in the Wing Tank harness installations to in-tank equipment on QT [Tank Quantity] circuit. The failure of a one or more ring tag crimp connections may result in the disconnection of the electrical wire with a possibility that the loose wire ends can contact the tank structure. When combined with a loss of equipment surface protection this constitutes a potential source of ignition in a fuel tank and consequent danger of fire or explosion. * * * * * This AD requires actions that are intended to address the unsafe condition described in the MCAI.

Models AT-802 and AT-802A Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: We are revising an existing airworthiness directive (AD) for Air Tractor, Inc. (Air Tractor) Models AT-802 and AT-802A airplanes. That AD currently requires you to repetitively inspect (using the eddy current method) the two outboard fastener holes in both of the wing main spar lower caps at the center splice joint for cracks and repair or replace any cracked spar, and changes the safe life for certain serial (SN) ranges. This AD retains the actions of AD 2010-17-18 and reduces the applicability from all serial numbers beginning with SN-0001 as required by the previous AD to SN-0001 through SN-0269. This AD was prompted by our evaluation of a comment from David Ligon, Air Tractor, and our determination that we should reduce the applicability from that already required by the previous AD. We are issuing this AD to detect and correct cracks in the wing main spar lower cap at the center splice joint, which could result in failure of the spar cap and lead to wing separation and loss of control of the airplane.

ACTION: Proposed rule; rescission. ----------------------------------------------------------------------- SUMMARY: We propose to rescind airworthiness directive (AD) 2009-18-19. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by EASA, to rescind EASA AD 2010-0083. The MCAI specifies the following: It has been assessed that multiple NRV [non return valve] failures in combination with certain trapped fuel cases could potentially increase the quantity of unusable fuel on the aeroplane, possibly leading to fuel starvation which could result in engines in-flight shut down and would constitute an unsafe condition. To prevent and detect this condition, EASA issued EASA AD 2010-0083. Based on in service experience, mainly on the results of the operational test required by EASA AD 2010-0083, Airbus has performed a safety analysis on the NRV to check if the safety objectives are met. This analysis of the Collector Cell motive flow line NRV, taking into account all failure scenarios, concludes that the previous non compliance can be alleviated. Consequently, no unsafe condition exists any more on the affected NRV. For the reasons described above, EASA AD 2010-0083 is cancelled. The proposed AD would rescind the parallel FAA AD 2009-18-19. DATES: We must receive comments on this proposed AD by February 14, 2011.

AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Following investigation of an in service event, it has been determined that in case a short circuit occurs on a weight-on-wheels (WOW) proximity sensor wiring, both circuit breakers that supply power to that wiring will trip, causing simultaneous de-power of all WOW proximity sensors of that part of the system. The loss of the corresponding WOW information would lead to untimely inhibition of warnings that could compromise the pilot capacity to react to abnormal or failure landing conditions. * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by February 14, 2011.

ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede an existing airworthiness directive (AD) that applies to certain Piper Aircraft, Inc. Models PA-46-310P and PA-46-350P airplanes that are equipped with a Lewis or Transicoil turbine inlet temperature (T.I.T.) gauge and associated probe. The existing AD currently

requires calibrating the T.I.T. system; replacing any T.I.T. system that fails the calibration test; repetitively replacing the T.I.T. probe on certain Model PA-46-350P airplanes; and inserting a copy of the AD into the pilot's operating handbook (POH) for certain airplanes. Since we issued that AD, the manufacturer has revised related service information and added an airplane model to the list of affected airplanes. This proposed AD would retain the actions required by AD 99-15-04 R1, add certain Model PA-46R-350T airplanes to the Applicability section, expand the applicability to include other T.I.T. systems, and incorporate new service information. We are proposing this AD to prevent improper engine operation caused by improperly calibrated T.I.T. indicators or defective T.I.T. probes, which could result in engine damage/failure with consequent loss of control of the airplane.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: We are revising an earlier proposed airworthiness directive (AD) for the products listed above. That NPRM proposed replacing the power control relays for the fuel boost pumps and override pumps with new relays having a ground fault interrupt (GFI) feature. That NPRM was prompted by results from fuel system reviews conducted by the manufacturer. This action revises that NPRM for all airplanes by proposing to require an electrical bonding resistance measurement for certain GFI relays to verify that certain bonding requirements are met. This action also revises that NPRM by proposing to require, for certain airplanes, an inspection to ensure that certain screws are properly installed, and re-installing longer screws if necessary. We are proposing this supplemental NPRM to prevent damage to the fuel pumps caused by electrical arcing that could introduce an ignition source in the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes. DATES: We must receive comments on this supplemental NPRM by January 28, 2011.

SUMMARY: We propose to supersede an existing airworthiness directive (AD) that applies to General Electric Company (GE) CF6-45 and CF6-50 series turbofan engines. The existing AD requires replacing certain forward and aft centerbodies of the long fixed core exhaust nozzle (LFCEN) assembly. Since we issued that AD, we became aware that other forward and aft centerbodies are also affected. This proposed AD would add certain new centerbodies requiring replacement. This proposed AD is prompted by the discovery of more part numbers (P/Ns) of centerbodies requiring replacement. We are proposing this AD to prevent the forward and aft centerbody of the LFCEN assembly from separating from the engine, damage to the engine, and damage to the airplane. DATES: We must receive comments on this proposed AD by February 18, 2011.

AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding an existing airworthiness directive (AD) that applies to the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Two reports have been received where, during inspection of the vertical stabilizer of F28 Mark 0100 aeroplanes, one of the bolts that connect the horizontal stabilizer control unit actuator with the dog-links was found broken (one on the nut side & one on the head side). In both occasions, the bolt shaft was still present in the connection and therefore the horizontal stabilizer function was not affected. If a single dog-link connection fails, the complete stabilizer load is taken up by the remaining dog-link connection. * * * To address and correct this unsafe condition EASA [European Aviation Safety Agency] issued AD 2007-0287 [corresponding FAA AD 2008-22-14] that required a one-time inspection of the affected bolts, * * * and replacement of failed bolts with serviceable parts. EASA AD 2007-0287 also required the installation of a tie wrap through the lower bolts of the horizontal stabilizer control unit, to keep the bolt in place in the event of a bolt head failure. Recent examination revealed that the bolts failed due to stress corrosion, attributed to excessive bolt torque. Investigation of the recently failed bolts showed that the modification as required by AD 2007-0287 is not adequate. * * * * * Loss of horizontal stabilizer function could result in partial loss of control of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective February 9, 2011.

Airworthiness Directives; The Boeing Company Model 737-300, -400, and -500 Series Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires repetitive inspections for discrepancies of the fuse pins of the inboard and outboard midspar fittings of the nacelle strut, and corrective actions if necessary. This new AD requires replacing the midspar fuse pins with new, improved fuse pins, which would terminate the repetitive inspections. This AD was prompted by a report of corrosion damage of the chrome runout on the head side found on all four midspar fuse pins of the nacelle strut. Additionally, a large portion of the chrome plate was missing from the corroded area of the shank. We are issuing this AD to prevent damage of the fuse pins of the inboard and outboard midspar fittings of the nacelle strut, which could result in reduced structural integrity of the fuse pins, and consequent loss of the strut and separation of the engine from the airplane. DATES: This AD is effective February 9, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of February 9, 2011.

SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: There have been two in-service reports of main landing gear (MLG) tire failure on landing, during which a flailing tire tread caused damage to No. 2 and No. 3 hydraulic system lines in the wing auxiliary spar area on the left side of the aircraft. This damage resulted in the loss of supply pressure to the inboard and outboard brakes, as the only remaining braking source available was the No. 3 hydraulic system accumulator. The degradation of the brake system performance could adversely affect the aircraft during landing. * * * * * The unsafe condition is loss of braking capability, which could reduce the ability of the flightcrew to safely land the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective February 9, 2011.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: It has been detected a short circuit in harness W101 due to its interference with the main door mechanism. Further analysis of the affected region has also revealed the possibility of chafing between the same harness and the oxygen tubing. The chafing of the wiring harness against the oxygen tubing could lead to a short circuit of the wiring harness and a subsequent fire in the airplane. Since this condition may occur in other airplanes of the same type and affects flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with this AD in the indicated time limit. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective February 9, 2011. On February 9, 2011, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as :During flight-testing of a wing anti-ice piccolo tube containing a deliberate small breach, it was determined that the wing leading edge thermal switches were not detecting the consequent bleed leak at the design threshold. As a result, new Airworthiness Limitation tasks, consisting of a functional test of the wing leading edge thermal switches and an inspection of the wing anti-ice duct piccolo tubes, have been introduced in order to limit exposure to dormant failure of the switches in the event of piccolo tube failure, which could potentially compromise the structural integrity of the wing leading edge and the effectiveness of the wing anti-ice system.

ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model 382, 382B, 382E, 382F, and 382G airplanes. The existing AD currently requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. That AD also requires the accomplishment of certain fuel system modifications, the initial inspections of certain repetitive fuel system limitations to phase in those inspections, and repair if necessary. This proposed AD would correct certain part number references, add an additional inspection area, and for certain airplanes, require certain actions to be re-accomplished according to revised service information. This proposed AD results from a report of incorrect accomplishment information in the service information cited by the existing AD. We are proposing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES: We must receive comments on this proposed AD by February 22, 2011.

ACTION: Proposed rule; withdrawal. ----------------------------------------------------------------------- SUMMARY: This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) to supersede an existing AD, applicable to certain Gulfstream Aerospace Corporation Model G-1159 airplanes. The existing AD requires an inspection to detect cracks or corrosion in the wing structure in the area of Fuselage Station (FS) 452 inboard clothespin attachment fitting, and repair if necessary. The proposed AD would have required repetitive inspections to detect corrosion or cracks in the forward and aft wing attach fittings at FS 345 and 452, respectively, and adjacent wing beam and wing plank areas, and repair if necessary; and the application of corrosion protection treatment. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data that indicate the aircraft maintenance manual has been revised to include additional inspections that address the unsafe condition detailed in the NPRM and that the full fleet is in compliance with the inspection and applicable repair required by the existing AD. Accordingly, the proposed rule is withdrawn.

AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. The original NPRM would have superseded an existing AD that currently requires reviewing the airplane maintenance records to determine whether an engine has been removed from the airplane since the airplane was manufactured. For airplanes on which an engine has been removed, the existing AD also requires an inspection of the aft engine mount to determine if the center link assembly is correctly installed, and follow-on actions if necessary. The original NPRM proposed to require the same actions for airplanes on which the engine has not been previously removed. The original NPRM resulted from reports indicating that operators found that the center link assembly for the aft engine mount was reversed on several airplanes that had not had an engine removed since delivery. This new action revises the original NPRM by expanding the applicability to include Model 737-900ER airplanes. We are proposing this supplemental NPRM to prevent increased structural loads on the aft engine mount, which could result in failure of the aft engine mount and consequent separation of the engine from the airplane. ADDRESSES: We must receive comments on this supplemental NPRM by February 25, 2011.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires a one-time inspection to detect damage of the wire assemblies of the tail tank fuel system, a wiring change, and corrective actions if necessary. This AD also requires, for certain airplanes, a general visual inspection for correct installation of the self-adhering high-temperature electrical insulation tape; installation of a wire assembly support bracket and routing wire assembly; changing wire supports; and installation of a wire protection bracket. This AD was prompted by fuel system reviews conducted by the manufacturer. We are issuing this AD to detect and correct a potential of ignition sources inside fuel tanks, which, in combination with flammable vapors, could result in a fuel tank fire or explosion, and consequent loss of the airplane. DATES: This AD is effective February 16, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of February 16, 2011.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are revising an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Findings of corrosion, wear and cracks in the upper wing strut fittings on some PC-6 aircraft have been reported in the past. It is possible that the spherical bearing of the wing strut fittings installed in the underwing can be loose in the fitting or cannot rotate because of corrosion. In this condition, the joint cannot function as designed and fatigue cracks may then develop. Undetected cracks, wear and/or corrosion in this area could cause failure of the upper attachment fitting, leading to failure of the wing structure and subsequent loss of control of the aircraft. To address this problem, FOCA published AD TM-L Nr. 80.627-6/Index 72-2 and HB-2006-400 and EASA published AD 2007-0114 to require specific inspections and to obtain a fleet status. Since the issuance of AD 2007-0114, the reported data proved that it was necessary to establish and require repetitive inspections. EASA published Emergency AD 2007-0241-E to extend the applicability and to require repetitive eddy current and visual inspections of the upper wing strut fitting for evidence of cracks, wear and/or corrosion and examination of the spherical bearing and replacement of cracked fittings. Collected data received in response to Emergency AD 2007-0241-E resulted in the issuance of EASA AD 2007-0241R1 that permitted extending the intervals for the repetitive eddy current and visual inspections from 100 Flight Hours (FH) to 300 FH and from 150 Flight Cycles (FC) to 450 FC, respectively. In addition, oversize bolts were introduced by Pilatus PC-6 Service Bulletin (SB) 57-005 R1 and the fitting replacement procedure was adjusted accordingly. Based on fatigue test results, EASA AD 2007-0241R2 was issued to extend the repetitive inspection interval to 1100 FH or 12 calendar months, whichever occurs first, and to delete the related flight cycle intervals and the requirement for the ``Mild Corrosion Severity Zone''. In addition, some editorial changes have been made for reasons of standardization and readability. Revision 3 of this AD referred to the latest revision of the PC-6 Aircraft Maintenance Manual (AMM) Chapter 5 limitations which have included the same repetitive inspection intervals and procedures already mandated in the revision 2 of AD 2007-0241. Besides the inspections, in the latest revision of the PC-6 AMM, the replacement procedures for the fittings were included. Additionally, EASA AD 2007-0241R3 introduced the possibility to replace the wing strut fitting with a new designed wing strut fitting. With this optional part replacement, in the repetitive inspection procedure the 1100 FH interval is deleted so that only calendar defined intervals of inspections remained applicable. We are issuing this AD to require actions to correct the unsafe condition on these products.

DATES: This AD becomes effective February 16, 2011. As of October 1, 2009 (74 FR 43636, August 27, 2009), the Director of the Federal Register approved the incorporation by reference of Pilatus Aircraft Ltd. Pilatus PC-6 Service Bulletin No. 57-005, REV No. 2, dated May 19, 2008; and Chapter 57-00-02 of Pilatus Aircraft Ltd.

ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require initial and repetitive fluorescent penetrant inspections (FPIs) and eddy current inspections (ECIs) of the high-pressure compressor rotor (HPCR) 8-10 stage spool, part numbers (P/Ns) 1844M90G01 and 1844M90G02, for cracks between the 9-10 stages, at each piece-part exposure. This proposed AD was prompted by cracks discovered on one HPCR 8-10 spool between the 9-10 stages in the weld joint. We are proposing this AD to prevent failure of the HPCR 8-10 stage spool, uncontained engine failure, and damage to the airplane. DATES: We must receive comments on this proposed AD by February 7, 2011.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: We are revising an earlier proposed airworthiness directive (AD) for certain Model 777-200, -200LR, -300, and -300ER series airplanes. The original NPRM would have required doing an inspection to identify the part number of the motor operated valve (MOV) actuators of the main and center fuel tanks; replacing certain MOV actuators with new MOV actuators; and measuring the electrical resistance of the bond from the adapter plate to the airplane structure, and doing corrective actions if necessary. The original NPRM also would have required revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This action revises the original NPRM by adding airplanes to the applicability. This action also revises the original NPRM by removing the requirement for revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness. We are proposing this supplemental NPRM to prevent electrical current from flowing through an MOV actuator into a fuel tank, which could create a potential ignition source inside the fuel tank. This condition, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES: We must receive comments on this supplemental NPRM by January 18, 2011.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Model 737-200, -300, -400, and -500 series airplanes. This AD requires repetitive inspections for cracking of certain fuselage frames and stub beams, and corrective actions if necessary. This AD also provides for an optional repair, which would terminate the repetitive inspections. For airplanes on which a certain repair is done, this AD also requires repetitive inspections for cracking of certain fuselage frames and stub beams, and corrective actions if necessary. This AD results from reports of the detection of fatigue cracks at certain frame sections, in addition to stub beam cracking, caused by high flight cycle stresses from both pressurization and maneuver loads. We are issuing this AD to detect and correct fatigue cracking of certain fuselage frames and stub beams and possiblesevered frames, which could result in reduced structural integrity of the frames. This reduced structural integrity can increase loading in the fuselage skin, which will accelerate skin crack growth and could result in rapid decompression of the fuselage.

----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above that are equipped with Thielert Aircraft Engine GmbH (TAE) Engine Model TAE-125-01 installed per Supplemental Type Certificate (STC) No. SA03303AT. This AD requires installing a full authority digital engine control (FADEC) backup battery, replacing the supplement pilot's operating handbook and FAA approved airplane flight manual, and revising the limitations section of the supplement airplane maintenance manual. This AD was prompted by an incident where an airplane experienced an in-flight engine shutdown caused by a momentary loss of electrical power to the FADEC. We are issuing this AD to prevent interruption of electrical power to the FADEC, which could result in an uncommanded engine shutdown. This failure could lead to a loss of engine power.

Model DHC-8-300 Series Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Several cases of aileron terminal quadrant support brackets that were manufactured using sheet metal have been found cracked on DHC-8 Series 300 aircraft. Investigation revealed that the failure of the support bracket was due to fatigue. Failure of the aileron terminal quadrant support bracket could result in an adverse reduction of aircraft roll control. * * * * *

These conditions could result in loss of control of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires a detailed inspection of the entryway door movable ceiling panel for pin migration at either end of the hinge assembly and damage to the pin; a detailed inspection for correct crimp at both ends and damage to hinge stock; a detailed inspection of the ceiling area for any visible cosmetic and/or tie-rod chafing that could be caused by a migrated hinge pin; a detailed inspection for wire damage and/or breakage; and other specified and corrective actions if necessary. This AD results from reports of fault messages caused by improperly crimped hinge pins coming into contact with wires and causing damage. We are issuing this AD to detect and correct improperly crimped hinge pins, which could damage tie rods and wire bundles, causing shorts in many systems, including the spar fuel shut-off valve, oxygen mask deployment, and burned wires, which could be an ignition source in a hidden area of the airplane.

ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: This amendment supersedes an existing emergency airworthiness directive (EAD) for the specified Sikorsky model helicopters. The EAD requires inspecting the LITEF Attitude Heading and Reference System (AHRS) unit of the navigation system to determine if it is at a Mod Status ``18.'' If either AHRS unit is at Mod Status ``18,'' the EAD requires installing placards on the instrument panel to prohibit single pilot instrument flight rule (IFR) and single pilot night flight and reducing airspeeds to 120 knots indicated airspeed (KIAS) if both autopilots uncouple during instrument meteorological conditions (IMC) or night flight. The EAD also requires inserting minimum crew and airspeed limitations into the Limitations section of the applicable Rotorcraft Flight Manual (RFM) to limit the minimumflight crew to 2 pilots for night flight and IFR flight and to reduce airspeed to 120 KIAS if both autopilots uncouple during IMC or night flight. This amendment contains the same requirements but draws the appropriate distinctions between IFR and IMC as used in the intended operating limitations. Also, unlike the EAD, this AD states the airspeed must be reduced to 120 KIAS if both autopilots uncouple during IMC or night flight. Further, we are removing the limitation contained in the Active Temporary Revisions relating to pilots keeping their hands and feet near the flight controls. This AD was prompted by the need to supersede the EAD to state the distinction between IFR and IMC as used in the operating limitations and to reduce the airspeed to 120 KIAS if both autopilots uncouple during IMC or night flight. The actions specified by this AD are intended to implement operating limitations based on an anomaly in the AHRS related to the 26 volt AC inverter that could result in a decoupling of both autopilots and to prevent loss of control of the helicopter during IMC and during night flight. DATES: Effective January 12, 2011. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of January 12, 2011. We must receive comments on this AD by February 28, 2011.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Model 747-200C, -200F, -400, -400D, and -400F series airplanes. That AD currently requires repetitive inspections for cracks in the overlapping (upper) skin of the upper fastener row of the lap joints of the fuselage skin in sections 41, 42, and 46; and related investigative and corrective actions, if necessary. This new AD expands the inspection area in the existing AD, and adds a modification of certain lap joints and certain post-repair inspections of the lap joints. Accomplishing the modification would end the repetitive inspections required by the existing AD for the length of lap joint that is modified. This AD results from a structural review of affected skin lap joints for widespread fatigue damage. We are issuing this AD to prevent fatigue cracking in certain lap joints, which could result in rapid depressurization of the airplane. DATES: This AD becomes effective February 1, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of February 1, 2011.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive inspections for cracking in the body skin around the aft corners of the nose wheel well; for certain airplanes, repetitive inspections for cracking in the skin splice plate at the aft corners of the nose wheel well; and related investigative and corrective actions if necessary. This AD also requires repetitive post-modification inspections for cracking in the body skin and the skin splice plate; for certain airplanes, an inspection for steel cross-shaped doublers on the larger aluminum doublers; and corrective action if necessary. This AD also requires repetitive surface high frequency eddy current (HFEC) inspections of a certain bulkhead outer chord, skin splice plate, and outer chord radius filler for cracking; repetitive detailed inspections for cracking of the bulkhead frame web and body skin; and corrective actions if necessary. This AD provides for optional terminating action for certain repetitive inspections. This AD was prompted by reports of cracking of the fuselage skin and adjacent internal skin splice plate at the left and right nose wheel well aft corners, and the outer chord of the body station (BS) 400 bulkhead. We are issuing this AD to detect and correct cracking of the fuselage skin or splice plate, which, together with cracking of the bulkhead outer chord, could result in large skin cracks and subsequent in-flight rapid decompression of the airplane.

This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: A manufacturing quality non-conformity has been identified that resulted in the under-crimping of ring tags on a batch of In-tank Fuel Harnesses. The affected ring tags are used to join individual electrical wires in the Wing Tank harness installations to in-tank equipment on QT [Tank Quantity] circuit. The failure of a one or more ring tag crimp connections may result in the disconnection of the electrical wire with a possibility that the loose wire ends can contact the tank structure. When combined with a loss of equipment surface protection this constitutes a potential source of ignition in a fuel tank and consequent danger of fire or explosion. * * * * * This AD requires actions that are intended to address the unsafe condition described in the MCAI.

ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: We are revising an existing airworthiness directive (AD) for Air Tractor, Inc. (Air Tractor) Models AT-802 and AT-802A airplanes. That AD currently requires you to repetitively inspect (using the eddy current method) the two outboard fastener holes in both of the wing main spar lower caps at the center splice joint for cracks and repair or replace any cracked spar, and changes the safe life for certain serial (SN) ranges. This AD retains the actions of AD 2010-17-18 and reduces the applicability from all serial numbers beginning with SN-0001 as required by the previous AD to SN-0001 through SN-0269. This AD was prompted by our evaluation of a comment from David Ligon, Air Tractor, and our determination that we should reduce the applicability from that already required by the previous AD. We are issuing this AD to detect and correct cracks in the wing main spar lower cap at the center splice joint, which could result in failure of the spar cap and lead to wing separation and loss of control of the airplane.

ACTION: Proposed rule; rescission. ----------------------------------------------------------------------- SUMMARY: We propose to rescind airworthiness directive (AD) 2009-18-19. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by EASA, to rescind EASA AD 2010-0083. The MCAI specifies the following: It has been assessed that multiple NRV [non return valve] failures in combination with certain trapped fuel cases could potentially increase the quantity of unusable fuel on the aeroplane, possibly leading to fuel starvation which could result in engines in-flight shut down and would constitute an unsafe condition. To prevent and detect this condition, EASA issued EASA AD 2010-0083. Based on in service experience, mainly on the results of the operational test required by EASA AD 2010-0083, Airbus has performed a safety analysis on the NRV to check if the safety objectives are met. This analysis of the Collector Cell motive flow line NRV, taking into account all failure scenarios, concludes that the previous non compliance can be alleviated. Consequently, no unsafe condition exists any more on the affected NRV. For the reasons described above, EASA AD 2010-0083 is cancelled. The proposed AD would rescind the parallel FAA AD 2009-18-19.

AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Following investigation of an in service event, it has been determined that in case a short circuit occurs on a weight-on-wheels (WOW) proximity sensor wiring, both circuit breakers that supply power to that wiring will trip, causing simultaneous de-power of all WOW proximity sensors of that part of the system. The loss of the corresponding WOW information would lead to untimely inhibition of warnings that could compromise the pilot capacity to react to abnormal or failure landing conditions. * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by February 14, 2011.

(Type Certificate Previously Held by The New Piper Aircraft, Inc.) Models PA-46-310P, PA-46-350P, and PA-46R-350T Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede an existing airworthiness directive (AD) that applies to certain Piper Aircraft, Inc. Models PA-46-310P and PA-46-350P airplanes that are equipped with a Lewis or Transicoil turbine inlet temperature (T.I.T.) gauge and associated probe. The existing AD currently

requires calibrating the T.I.T. system; replacing any T.I.T. system that fails the calibration test; repetitively replacing the T.I.T. probe on certain Model PA-46-350P airplanes; and inserting a copy of the AD into the pilot's operating handbook (POH) for certain airplanes. Since we issued that AD, the manufacturer has revised related service information and added an airplane model to the list of affected airplanes. This proposed AD would retain the actions required by AD 99-15-04 R1, add certain Model PA-46R-350T airplanes to the Applicability section, expand the applicability to include other T.I.T. systems, and incorporate new service information. We are proposing this AD to prevent improper engine operation caused by improperly calibrated T.I.T. indicators or defective T.I.T. probes, which could result in engine damage/failure with consequent loss of control of the airplane. DATES: We must receive comments on this proposed AD by February 14, 2011.

ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Model DC-10-10, DC-10-10F, and MD-10-10F airplanes. This proposed AD would require repetitive inspections for cracking on the lower cap of the rear spar of the left and right wings between stations Xors=417 and the outboard edge of the lower cap splice of the wing rear spar at station Xors=400; temporary and permanent repairs if necessary; and repetitive inspections of repaired areas and corrective actions if necessary. This proposed AD results from reports of three instances of fuel leaks in the lower cap splice of the wing rear spar at station Xors=409. We are proposing this AD to detect and correct cracking on the lower cap of the rear spar of the left and right wings between stations Xors=417 and the outboard edge of the lower cap splice of the wing rear spar at station Xors=400, which could result in fuel leaks or cracking of the lower wing skin and structure, causing possible inability of the structure to sustain the limit load adversely affecting the structural integrity of the airplane.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: We are revising an earlier proposed airworthiness directive (AD) for the products listed above. That NPRM proposed replacing the power control relays for the fuel boost pumps and override pumps with new relays having a ground fault interrupt (GFI) feature. That NPRM was prompted by results from fuel system reviews conducted by the manufacturer. This action revises that NPRM for all airplanes by proposing to require an electrical bonding resistance measurement for certain GFI relays to verify that certain bonding requirements are met. This action also revises that NPRM by proposing to require, for certain airplanes, an inspection to ensure that certain screws are properly installed, and re-installing longer screws if necessary. We are proposing this supplemental NPRM to prevent damage to the fuel pumps caused by electrical arcing that could introduce an ignition source in the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes. DATES: We must receive comments on this supplemental NPRM by January 28, 2011.

SUMMARY: We propose to supersede an existing airworthiness directive (AD) that applies to General Electric Company (GE) CF6-45 and CF6-50 series turbofan engines. The existing AD requires replacing certain forward and aft centerbodies of the long fixed core exhaust nozzle (LFCEN) assembly. Since we issued that AD, we became aware that other forward and aft centerbodies are also affected. This proposed AD would add certain new centerbodies requiring replacement. This proposed AD is prompted by the discovery of more part numbers (P/Ns) of centerbodies requiring replacement. We are proposing this AD to prevent the forward and aft centerbody of the LFCEN assembly from separating from the engine, damage to the engine, and damage to the airplane.

AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding an existing airworthiness directive (AD) that applies to the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Two reports have been received where, during inspection of the vertical stabilizer of F28 Mark 0100 aeroplanes, one of the bolts that connect the horizontal stabilizer control unit actuator with the dog-links was found broken (one on the nut side & one on the head side). In both occasions, the bolt shaft was still present in the connection and therefore the horizontal stabilizer function was not affected. If a single dog-link connection fails, the complete stabilizer load is taken up by the remaining dog-link connection. * * * To address and correct this unsafe condition EASA [European Aviation Safety Agency] issued AD 2007-0287 [corresponding FAA AD 2008-22-14] that required a one-time inspection of the affected bolts, * * * and replacement of failed bolts with serviceable parts. EASA AD 2007-0287 also required the installation of a tie wrap through the lower bolts of the horizontal stabilizer control unit, to keep the bolt in place in the event of a bolt head failure. Recent examination revealed that the bolts failed due to stress corrosion, attributed to excessive bolt torque. Investigation of the recently failed bolts showed that the modification as required by AD 2007-0287 is not adequate. * * * * * Loss of horizontal stabilizer function could result in partial loss of control of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective February 9, 2011.

Airworthiness Directives; The Boeing Company Model 737-300, -400, and -500 Series Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires repetitive inspections for discrepancies of the fuse pins of the inboard and outboard midspar fittings of the nacelle strut, and corrective actions if necessary. This new AD requires replacing the midspar fuse pins with new, improved fuse pins, which would terminate the repetitive inspections. This AD was prompted by a report of corrosion damage of the chrome runout on the head side found on all four midspar fuse pins of the nacelle strut. Additionally, a large portion of the chrome plate was missing from the corroded area of the shank. We are issuing this AD to prevent damage of the fuse pins of the inboard and outboard midspar fittings of the nacelle strut, which could result in reduced structural integrity of the fuse pins, and consequent loss of the strut and separation of the engine from the airplane. DATES: This AD is effective February 9, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of February 9, 2011. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of November 13, 2008 (73 FR 59493, October 9, 2008).

SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: There have been two in-service reports of main landing gear (MLG) tire failure on landing, during which a flailing tire tread caused damage to No. 2 and No. 3 hydraulic system lines in the wing auxiliary spar area on the left side of the aircraft. This damage resulted in the loss of supply pressure to the inboard and outboard brakes, as the only remaining braking source available was the No. 3 hydraulic system accumulator. The degradation of the brake system performance could adversely affect the aircraft during landing. * * * * * The unsafe condition is loss of braking capability, which could reduce the ability of the flightcrew to safely land the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective February 9, 2011. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 9, 2011.

ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model 382, 382B, 382E, 382F, and 382G airplanes. The existing AD currently requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. That AD also requires the accomplishment of certain fuel system modifications, the initial inspections of certain repetitive fuel system limitations to phase in those inspections, and repair if necessary. This proposed AD would correct certain part number references, add an additional inspection area, and for certain airplanes, require certain actions to be re-accomplished according to revised service information. This proposed AD results from a report of incorrect accomplishment information in the service information cited by the existing AD. We are proposing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES: We must receive comments on this proposed AD by February 22, 2011.

ACTION: Proposed rule; withdrawal. ----------------------------------------------------------------------- SUMMARY: This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) to supersede an existing AD, applicable to certain Gulfstream Aerospace Corporation Model G-1159 airplanes. The existing AD requires an inspection to detect cracks or corrosion in the wing structure in the area of Fuselage Station (FS) 452 inboard clothespin attachment fitting, and repair if necessary. The proposed AD would have required repetitive inspections to detect corrosion or cracks in the forward and aft wing attach fittings at FS 345 and 452, respectively, and adjacent wing beam and wing plank areas, and repair if necessary; and the application of corrosion protection treatment. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data that indicate the aircraft maintenance manual has been revised to include additional inspections that address the unsafe condition detailed in the NPRM and that the full fleet is in compliance with the inspection and applicable repair required by the existing AD. Accordingly, the proposed rule is withdrawn.

AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. The original NPRM would have superseded an existing AD that currently requires reviewing the airplane maintenance records to determine whether an engine has been removed from the airplane since the airplane was manufactured. For airplanes on which an engine has been removed, the existing AD also requires an inspection of the aft engine mount to determine if the center link assembly is correctly installed, and follow-on actions if necessary. The original NPRM proposed to require the same actions for airplanes on which the engine has not been previously removed. The original NPRM resulted from reports indicating that operators found that the center link assembly for the aft engine mount was reversed on several airplanes that had not had an engine removed since delivery. This new action revises the original NPRM by expanding the applicability to include Model 737-900ER airplanes. We are proposing this supplemental NPRM to prevent increased structural loads on the aft engine mount, which could result in failure of the aft engine mount and consequent separation of the engine from the airplane. ADDRESSES: We must receive comments on this supplemental NPRM by February 25, 2011.

This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to

identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: There have been four reports of loose or detached main landing gear torque link apex pin locking plate and the locking plate retainer bolt. This condition could result in torque link apex pin disengagement, heavy vibration during landing, damage to main landing gear components and subsequent main landing gear collapse. * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are revising an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Findings of corrosion, wear and cracks in the upper wing strut fittings on some PC-6 aircraft have been reported in the past. It is possible that the spherical bearing of the wing strut fittings installed in the underwing can be loose in the fitting or cannot rotate because of corrosion. In this condition, the joint cannot function as designed and fatigue cracks may then develop. Undetected cracks, wear and/or corrosion in this area could cause failure of the upper attachment fitting, leading to failure of the wing structure and subsequent loss of control of the aircraft. To address this problem, FOCA published AD TM-L Nr. 80.627-6/Index 72-2 and HB-2006-400 and EASA published AD 2007-0114 to require specific inspections and to obtain a fleet status. Since the issuance of AD 2007-0114, the reported data proved that it was necessary to establish and require repetitive inspections. EASA published Emergency AD 2007-0241-E to extend the applicability and to require repetitive eddy current and visual inspections of the upper wing strut fitting for evidence of cracks, wear and/or corrosion and examination of the spherical bearing and replacement of cracked fittings. Collected data received in response to Emergency AD 2007-0241-E resulted in the issuance of EASA AD 2007-0241R1 that permitted extending the intervals for the repetitive eddy current and visual inspections from 100 Flight Hours (FH) to 300 FH and from 150 Flight Cycles (FC) to 450 FC, respectively. In addition, oversize bolts were introduced by Pilatus PC-6 Service Bulletin (SB) 57-005 R1 and the fitting replacement procedure was adjusted accordingly. Based on fatigue test results, EASA AD 2007-0241R2 was issued to extend the repetitive inspection interval to 1100 FH or 12 calendar months, whichever occurs first, and to delete the related flight cycle intervals and the requirement for the ``Mild Corrosion Severity Zone''. In addition, some editorial changes have been made for reasons of standardization and readability. Revision 3 of this AD referred to the latest revision of the PC-6 Aircraft Maintenance Manual (AMM) Chapter 5 limitations which have included the same repetitive inspection intervals and procedures already mandated in the revision 2 of AD 2007-0241. Besides the inspections, in the latest revision of the PC-6 AMM, the replacement procedures for the fittings were included. Additionally, EASA AD 2007-0241R3 introduced the possibility to replace the wing strut fitting with a new designed wing strut fitting. With this optional part replacement, in the repetitive inspection procedure the 1100 FH interval is deleted so that only calendar defined intervals of inspections remained applicable. We are issuing this AD to require actions to correct the unsafe condition on these products.

DATES: This AD becomes effective February 16, 2011. As of October 1, 2009 (74 FR 43636, August 27, 2009), the Director of the Federal Register approved the incorporation by reference of Pilatus Aircraft Ltd.

(EMBRAER) Model EMB-500 Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: It has been found that moisture may accumulate and freeze, under certain conditions, in the gap between the AOA vane base assembly and the stationary ring of the sensor's body. If freezing occurs both AOA sensors may get stuck and the Stall Warning Protection System (SWPS) will be no longer effective without alerting. This may result in inadvertent aerodynamic stall and loss of controllability of the airplane. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by March 17, 2011.

ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Model 777-200 and -300 series airplanes. This proposed AD would require repetitive inspections of all thrust reverser (T/R) structure and sealant for degradation, and related investigative and corrective actions if necessary. This proposed AD results from reports of thrust reverser events related to thermal damage of the thrust reverser inner wall. We are proposing this AD to detect and correct a degraded T/R inner wall panel, which could lead to failure of a T/R and adjacent components and their consequent separation from the airplane, which could result in a rejected takeoff (RTO) and cause asymmetric thrust and consequent loss of control of the airplane during reverse thrust operation.

Airworthiness Directives; Saab AB, Saab Aerosystems Model SAAB 340A (SAAB/SF340A) and SAAB 340B Airplanes Modified in Accordance With Supplemental Type Certificate (STC) ST00224WI-D, ST00146WI-D, or SA984GL-D AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: We are revising an earlier proposed airworthiness directive (AD) for certain Saab AB, Saab Aerosystems Model SAAB 340A (SAAB/SF340A) and SAAB 340B airplanes. The first supplemental NPRM would have required inspecting the fuselage surface for corrosion and cracking behind the external adapter plate of the antennae installation, and repair if necessary. The first supplemental NPRM resulted from a report of a crack found behind the external adapter plate of the antennae during inspection. Similar cracking was found on two additional airplanes, and extensive corrosion was found on one airplane. This action revises the first supplemental NPRM by correcting an STC number, which would expand the applicability of the first supplemental NPRM. We are proposing this second supplemental NPRM to detect and correct corrosion and cracking behind the external adapter plate of the antennae of certain damage-tolerant structure, which could result in reduced structural integrity and consequent rapid depressurization of the airplane. DATES: We must receive comments on this supplemental NPRM by March 7, 2011.

ACTION: Notice of proposed rulemaking (NPRM). -----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Model 777-200 and -300 series airplanes. This proposed AD would require repetitive inspections for hydraulic fluid contamination of the interior of the strut disconnect assembly; repetitive inspections for discrepancies of the interior of the strut disconnect assembly, if necessary; repetitive inspections of the exterior of the strut disconnect assembly for cracks, if necessary; and corrective action if necessary. This proposed AD also provides an optional terminating action for the inspections. This proposed AD results from reports of system disconnect boxes that have been contaminated with hydraulic fluid and, in one incident, led to subsequent cracking of titanium parts in the system disconnect assembly. We are proposing this AD to detect and correct hydraulic fluid contamination, which can cause cracking of titanium parts in the system disconnect assembly, resulting in compromise of the engine firewall. A cracked firewall can allow fire in the engine area to enter the strut and can lead to an uncontained engine strut fire if flammable fluid is present. Cracking of the disconnect box may also reduce the effectiveness of the fire extinguishing system in the engine compartment and could contribute to an uncontained engine fire. In addition, a cracked disconnect box can leak flammable fluids into the engine core, which can initiate an engine fire, and lead to one or both fire conditions discussed above. DATES: We must receive comments on this proposed AD by March 7, 2011.

Model F406 Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: In early 2005, several reports had been received regarding discovery of cracks in rudder pulley brackets installed on Reims F406 aeroplanes. This pulley bracket, Part Number (P/N) 6015511-1, is installed on aeroplanes with the optional ``Camera Hole'' modification.

This condition, if not detected and corrected, could result in the loss of rudder control on the airplane. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by March 7, 2011.

ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would result in all airplanes having new relays with a ground fault interrupter (GFI) feature. This proposed AD would require, depending on airplane configuration, doing certain wiring changes, replacing the fuel pump power control relays for the main, center and auxiliary tanks, as applicable, with new relays having a GFI feature, performing certain bonding resistance measurements, and modifying relay module assemblies. The proposed AD also would require revising the maintenance program to incorporate Airworthiness Limitations (AWLs) 28-AWL-23 (for Model 737-100, 737-200, and 737-200C series airplanes), and 28-AWL-22 (for Model 737-300, 737-400, and 737-500 series airplanes). This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent damage to the fuel pumps caused by electrical arcing that could introduce an ignition source in the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES: We must receive comments on this proposed AD by March 7, 2011.

ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD supersedes Emergency AD 2011-01-51, requires an immediate functional test of the fuselage drain holes, and requires sending a report of the results to the FAA. This AD also allows, with noted exceptions, for the return/position of the airplane to a home base, hangar, maintenance facility, etc. This AD was prompted by reports of water accumulation in the belly of the fuselage that froze and caused the flight controls to jam. We are issuing this AD to prevent water or fluid from accumulating in the belly of the fuselage and freezing when the aircraft reaches and holds altitudes where the temperature is below the freezing point. This condition could cause the flight controls to jam with consequent loss of control.

ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Following the rupture of an alternator and vapour cycle cooling system pulley drive assembly, the AD 2008-0067-E was published to require the replacement of the pulley drive assembly by a new one of an improved design. Later on, cases of rupture of the alternator and vapour cycle cooling system compressor drive shaft and of cracks on the standby-alternator and compressor support were reportedly found. Such failures could lead to the loss of the alternator and of the vapour cycle cooling systems, and could also cause mechanical damage inside the power plant compartment. To address this condition, the AD 2008-0129-E superseded AD 2008-0067-E and mandates the removal, as a temporary measure, of the compressor drive belt and of the torque limiter, the conditional replacement of the pulley drive shear shaft, and repetitive inspections for cracks of the pulley drive assembly and of the alternator/compressor support. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective March 1, 2011. On March 1, 2011, the Director of the Federal Register approved the incorporation by reference of SOCATA Mandatory TBM Aircraft Service Bulletin SB 70-176, amendment 1, dated February, 2010, listed in this AD.
