231.1.8. Aircraft Maintenance Logbooks

Logbook records add value to aircraft performance,logbook records can help you spot recurring problems,logbook records can protect you against liability. If you do not log it it did not happen,Logbook records are proof that you are completing inspections and performing routine maintenance,Ideally, three logbooks should be used: (1) airframe, (2) engine and (3) propeller. It is legal to have one logbook with an index for each of the above.24

1.2. Minimum Equipment List

MEL, is a categorized list of systems, instruments and equipment on an aircraft that may be inoperative for flight. The MEL is defined on a per aircraft model basis.MEL need not include items like wings, flight controls, complete engines, landing gears etc., the airworthiness and correct functioning of which is absolutely necessary before any flight. It may also not include items like galley equipment, entertainment systems, passenger convenience equipment, which do not affect the airworthiness of an aircraft. All items which affect the airworthiness of aircraft or safety of those carried on board and are not included in MEL are automatically required to be operative.28Cont. A Minimum Equipment List (MEL) is an FAA approved document that allows an aircraft owner/operator to fly with a certain item(s) inoperative. The FAA produces a Master Minimum Equipment List (MMEL) for most aircraft to use. They provide the format that is acceptable to the administrator.

A minimum equipment list (MEL) - subject to specified conditions, prepared by an operator (ICAO Annex 6: Operation of Aircraft).

The master minimum equipment list (MMEL) -for a particular aircraft type by the organization. The MMEL may be associated with special operating conditions, limitations or procedures. (ICAO Annex 6: Operation of Aircraft).

29Maintenance Related DocumentsCode of Federal Regulations (CFRs)FAA regulations that govern todays aircraft are found in Title 14 of the Code of Federal Regulations (14 CFR).There are 68 regulations organized:Into three volumes under Title 14, Aeronautics and Space. A fourth volume deals with the Department of Transportation, and the fifth volume is focused on NASA.30CFR 14 chaptersCHAPTER I - FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATIONCHAPTER II - OFFICE OF THE SECRETARY, DEPARTMENT OF TRANSPORTATION (AVIATION PROCEEDINGS)CHAPTER III - COMMERCIAL SPACE TRANSPORTATION, FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATIONCHAPTER V - NATIONAL AERONAUTICS AND SPACE ADMINISTRATIONCHAPTER VI - AIR TRANSPORTATION SYSTEM STABILIZATION31Cont. 1.3.1. Code of Federal Regulations (CFRs)There are three primary regulations that govern the airworthiness of an aircraft. The Big Three are:14 CFR Part 21 Certification Procedures for Products and Parts,14 CFR Part 43 Maintenance, Prventive Maintenance, Rebuilding, and Alterations,14 CFR Part 91 General Operating and Flight Rules,-established by law to provide for the safe & orderly conduct of flight operation & to prescribe airmen privileges and limitations,32Advisory Circulars (ACs)The FAA issues ACs to inform the aviation public in a systematic way of non-regulatory material. provide guidance and information in a designated subject area,or to show a method acceptable to the Administrator for complying with a related federal aviation regulation.ACs are issued in a numbered-subject system corresponding to the subject areas of the Federal Aviation Regulations,33

34Airworthiness Directives (ADs)

Require correction of unsafe conditions by notification to owners and operators of certified aircraft that a known safety deficiency with a particular model of aircraft, engine, avionics or other system exists.ADs may be divided into two categories:Those of an emergency nature requiring immediate compliance prior to further flight, andThose of a less urgent nature requiring compliance within a specified period of time.

35Aircraft ListingsThis document contains the specifications and data for certificated aircraft when the number of registered aircraft is 50 or fewer.36Aircraft Specifications

Specifications were originated during implementation of the Air Commerce Act of 1926. Specifications are FAA recordkeeping documents issued for both type certificated and non-type-certificated products,Specifications covering type-certificated products may be converted to type certificate data sheets at the option of the type certificate holder. However, to do so requires the type certificate holder to provide an equipment list. A specification is not part of a type certificate. Specifications are subdivided into five major groups as follows: Type Certificate , Approvals, Engine Ratings, Engine Approvals37

Aviation Maintenance Alerts (AC 43-16)

Monthly electronic publication of the FAA that provides information concerning malfunction or defects observed by technicians throughout the aviation industry.

The data is supplied to the FAA on FAA Form 8010-4, Malfunction or Defect Report, which may be submitted to the FAA either electronically via the Internet, or by downloading a paper copy and completing it manually. 38Supplemental Type Certificates (STC)

Is a document issued by the FAA approving a product (aircraft, engine, or propeller) modification. The STC defines the product design change, states how the modification affects the existing type design, and lists serial number effectivity. It also identifies the certification basis listing specific regulatory compliance for the design change. The STC and its supporting data (drawings, instructions, specifications, and so forth) are the property of the STC holder. You must contact the STC holder to obtain rights for the use of the STC.39

40Type Certificate Data Sheets (TCDS)

Is a formal description of the aircraft, engine, or propeller. It lists limitations and information required for type certification including airspeed limits, weight limits, thrust limitations, and so forth.Type certificate data sheets and specifications set forth essential factors and other conditions which are necessary for U.S. airworthiness certification. Aircraft, engines, and propellers which conform to a U.S. type certificate (TC) are eligible for U.S. airworthiness certification when found to be in a condition for safe operation and ownership requisites are fulfilled.

41Cont. Type certificate data sheets were originated and firstpublished in January 1958. 14 CFR part 21, 21.41 indicates they are part of the type certificate. As such, a type certificate data sheet is evidence the product has been type certificated. Generally, type certificate data sheets are compiled from details supplied by the type certificate holder; however, the FAA may request and incorporate additional details when conditions warrant.Under federal law, no civil aircraft registered in the United States can operate without a valid airworthiness certificate. 42Cont. This certificate must be approved and issued by the FAA; and it will only be issued if the aircraft and its engines, propellers, and appliances are found to be airworthy and meet the requirements of an FAA-approved type certificate. The FAA issues a type certificate when a new aircraft, engine, propeller, and so forth, is found to meet safety standards setforth by the FAA. The TCDS lists the specifications, conditions, and limitations under which airworthiness requirements were met for the specified product, such as engine make and model, fuel type, engine limits, airspeed limits, maximum weight, minimum crew, and so forth. TCDSs are issued and revised as necessary to accommodate new models or other major changes in the certified product. TCDSs are categorized by TCD holder and product type.43

44

Air Transport Association (ATA) Specifications

To standardize the technical data and maintenance activities on large and therefore complex aircraft, the ATA has established a classification of maintenance related actions.

These are arranged with sequential numbers assigned to ATA chapters.

These chapters are consistent regardless of which large aircraft is being worked on. 45

46

Using Industry Manuals

47

Accessing Industry Manuals, Specifications & Drawings

The original equipment manufacturer (OEM) is usually the best source of information for the operation of and maintenance on a particular product.

The manufacturer is required by 14 CFR part 21, 21.5 to provide a current approved airplane or rotorcraft flight manual and (if applicable) a rotorcraft maintenance manual. 48Identification Of Aircraft Hardware, Materials & Components

Is identified for use by its specification number or trade name. Threaded fasteners and rivets are identified by Air Force-Navy (AN), National Aircraft Standard (NAS), and Military Standard (MS) numbers. Quick-release fasteners are identified by factory trade names and size designations.Materials and components can be identified as per the description manuals,

49

Calculating Dimensions From Drawings

Calculating allowable dimension variations on a component from information in drawing title blocks and drawings,

Calculating dimensions from drawings for the purpose of manufacturing aircraft components and hardware,50

Use of the Industry Manuals, Specifications & Drawings

Locating & Interpreting Relevant Chapter Or Section Of A ManualAppropriate manuals are identified and accessed for the type of aircraft or component to be maintained. Amendment status is clearly established to ensure the correct specifications and procedures are applied. Relevant chapter or section of manual or drawing is located in relation to the work to be carried out. Information is interpreted and procedures to be followed are accurately determined.

51Identifying & Interpreting Information from Drawings & DiagramsDocumentation requirements are determined and accessed, where necessary, from relevant sources in accordance with regulatory and enterprise procedures.Information contained in existing documentation is interpreted correctly and, where necessary, requirements carried out in accordance with regulatory and enterprise procedures52

Identifying & Applying Work Steps on the Manual

Work steps are correctly identified in accordance with manual or specification procedures.All correct sequencing and adjustments are interpreted in accordance with information contained in industry manuals or specifications.Manual, specification or drawing changes and/or amendments are incorporated documented correctly in accordance with statutory regulations and/or enterprise.

53 Storing Manuals

54Storage of Manuals, Specifications Or Drawings

Manuals, specifications or drawings are stored appropriately to ensure prevention ready access and updating of information, when required, in accordance with enterprise procedures

prepare an expandable file folder sectioned off by the alphabet.

Gather your manuals. Sort these manuals according the alphabet.

Check each manual to make sure that you still have that appliance.55

3.2. Requirements For Custody & Upkeep Of Industry Manuals

14 CFR Part 91.417 spells out what maintenance records are required and how long those records must be kept by the owner/operator. Two different categories. Category A (permanent records) and Category B (expiring records).Category A records are those maintenance records that must be kept and maintained for the aircraft indefinitely. Category A records reflect the current status of the aircraft with respect to issues such as inspections, life-limited parts, major changes to type design, and AD compliance.Looking at 14 CFR Part 91.417 (a)(2) we see the list of records that must be retained and transferred with the aircraft at the time the aircraft is sold (Ref 14 CFR Part 91.417(b)(2)). 56

Cont. Temporary Records 14 CFR 91.417(a)(1) and (b)(1)

These are records that must be kept by the owner until the work is repeated, superseded, or 1 year has transpired since the work was performed.

These are typically records referring to maintenance, preventive maintenance, alteration, and all inspections. They include a description of the work performed (or reference to the FAA-accepted data); the date of completion; and the name, signature and certificate number of the person doing the return to service (RTS).5758

4. Maintenance Documentation Requirement59Maintenance TerminologiesNEW ENGINE:A new engine is one that has been manufactured from all new parts and tested by an FAA-approved manufacturer. NEW LIMITS:These are the FAA-approved fits and clearances manufacturers adhere to with new engine.SERVICE LIMITS:The service limits are the FAA-approved allowable wear fits and tolerances to which a new limit part may deteriorate and still be a useable component. OVERHAULED ENGINE:An engine that has been disassembled, cleaned, inspected, repaired in accordance with manufacture overhaul instructions and tested using FAA-approved procedures.REBUILT ENGINE:This is an engine that has been overhauled using new and used parts to new limits by the manufacturer or an entity approved by the manufacturer.

Required Maintenance Documentations

Display your aircrafts Airworthiness Certificate, issued by the Federal Aviation Administration,Ensure your aircraft has a Registration Certificate if you will be flying it in National Air Space, Radio Station License if you plan to undertake any international flights. Get the license by completing Form 605, available from the Federal Communications Commission, Check that a copy of your aircrafts Operating Limitations are on board, which refers to a number of documents; both a Pilots Operating Handbook and a FAA-approved Airplane Flight Manual,Ensure you have a copy of the weight and balance information for your aircraft. These are initially provided by the manufacturer, but you will have to get new weight and balance documentation every time you adjust the aircraft; 61

Regulatory & Enterprise Documentation Procdures

Certification of aircraft by the FAA ensures that commercial and general aviation aircraft meet the highest safety standards, from initial design to retirement. It outlines the aircraft certification processes, lists important aircraft safety information, and provides guidance on general aviation aircraft.625. Maintenance Records & Forms63

Additional data for which there is no designated place in the logbook are inserted in a manila envelope, which is pasted inside the back of the binder.

This envelope should not become a catchall for data that should be an entry in the logbook, or that is not pertinent to the purpose of the logbook.

69Cont. Recording Of Major Repairs & Alterations

In most cases when a major repair or alteration is accomplished, FAA Form 337, Major Repair or Alteration, is completed at least in duplicate with the original going to the aircraft owner and a copy sent to the FAA Aircraft,If a certificated repair station completes a major repair, it may provide the customer with a signed copy of the work order and a maintenance release signed by an authorized representative of the repair station, instead of the FAA Form 337.If extended range tanks are installed in either passenger or cargo compartments, the technician must generate a third FAA Form 337 for the modification.This copy must be placed and retained in the aircraft. (Refer to 91.417(d).)

70Maintenance Record Content & Entries

Aircraft Repair Entries

Excludes inspection entries (those are covered in43.11). This section deals exclusively with maintenance record entries.As stated in the explanation of 43.3, a certificated pilot is authorized to perform preventive maintenance on the aircraft he or she owns or operates, must make a record entry of the preventive maintenance There are three distinct issues to be addressed in the maintenance entry, and they answer the questions of what? when? and who?

71Cont.

A signed copy shall be given to the owner and another copy sent to the local FSDO within 48 hours after the aircraft has been approved for return to service. However, when a major repair is done by a certificated repair station, the customer's work order may be used and a release given as outlined in Appendix B of FAR Part 43.

76Cont. Preventive Maintenance Recording RequirementsIdentify equipment that need PM to achieve conformity to product requirements,Determine and define the methods of PM (usually detailed by manufacturer of equip. in user manuals) Determine & define frequencies of PM (usually detailed by manufacturer of equip. in user manuals) Provide evidence (records) that PM's were done per schedule & method

77FormsAirworthiness Certificates

A Certificate of Airworthiness (CoA), or an airworthiness certificate, is issued for an aircraft by the national aviation authority in the state in which the aircraft is registered.

Each airworthiness certificate is issued in one of a number of different categories.(Transport, Acrobatic, Manned free balloons,.)

A certificate of airworthiness is issued when the aircraft is registered in the name of the owner. 78Cont. Aircraft Registration14 CFR Part 47 Aircraft Registration This regulation provides the requirements for registering aircraft.

It includes procedures for both owner and dealer registration of aircraft.

This registration is accomplished by the use of FAA Form 8050-1, Aircraft Registration Application.

The white original and the green copy must be submitted to the FAA Aircraft Registration Branch (AFS-750).79Cont. The pink copy serves as the temporary authority to operate the aircraft until the official registration is received from AFS-750, and is valid for a maximum of 90 days.

A successful review of the application will result in the issuance of AC Form 8050-3, Certificate of Aircraft Registration. (Note the AC prefix.)

If the registration is ever lost or damaged, it may be replaced by contacting the FAA Aircraft Registration Branch and providing them with the aircraft specific data, including make, model, N-number, and serial number.

80Cont. 5.3.3. Radio Station LicenseIs required if the aircraft is equipped with radios, and the aircraft is planned to be flown outside the boundaries.

A radio station license is not required for aircraft that are operated domestically. (A major change occurred on February 8, 1996, when the telecommunications Act of 1996 was signed into law.)

The Federal Communications Commission (FCC) formerly required that any communication transmitter installed in aircraft be licensed.

These FCC licenses were valid for 5 years. Note that this is not an FAA requirement. 81Cont. 5.3.4. Operating Instructions

Aircraft Operating Instructions must list the specific title or company identifier for the Aircraft Operating Instructions (AOI) provided with the light-sport kit or aircraft, including the revision level, if applicable. The Aircraft Operating Instructions also must contain the consensus standard used to develop the AOI.82Cont. 5.3.5.

5.4.1. Maintenance Logs

A close counterpart to the system configuration document is the maintenance log.

A maintenance log is a document (often relatively simple) that records who did what, when, and why. ...

Maintenance logs are extremely useful for troubleshooting recurring or obscure problems, 87Cont. 5.4.2. Service Tags Or Removal Tags88

Cont.

5.4.4. Process Sheet & Task CardA typical process sheet consists of the following sections:Product/system description: what to produce or install

Process description: what stages are involved in product/system manufacturing/installation

Procedures & instructions: how to produce/install the product/system

89Cont.

Labor & technology: who will produce/install the product/system and what tools & equipment will be used

Budget: what amount of funds is required to implement the process

Process sheets are developed for various departments and workshops as guidelines that explain how to perform installation or manufacturing of certain products/systems.

90Cont. 5.4.5. Material Safety Data Sheet (MSDS) Or Material Record SheetsIs an important component of product stewardship and occupational safety and health.

It is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner,

MSDS formats can vary from source to source within a country depending on national requirements.

Cont. 5.4.7. Maintenance Reports

14 CFR Part 25 Aircraft Aviation safety Reporting and recordkeeping requirements (operation vs maintenance)IFF inoperative. [IFF = Identification, Friend or Foe.].---. IFF always inoperative in 'off' mode.

Evidence of leak on right main landing gear.---. Evidence removed. The FAA publishes alerts regarding aviation maintenance, as a way to share information between those who maintain and operate aviation products. For metallurgists or materials scientists it may be interesting to see what sort of problems occur and can be remedied during maintenance. Good to see these appear rather than accident reports.

93

Cont.

5.4.8. Irregularity Reports 135.65Reporting mechanical irregularities.

Each certificate holder shall provide an aircraft maintenance log to be carried on board each aircraft for recording or deferring mechanical irregularities and their correction.

The pilot in command shall enter or have entered in the aircraft maintenance log each mechanical irregularity that comes to the pilot's attention during flight time.

946. Completing Maintenance Documentation Forms95

6.1. Information Requirements for Documentation

FAR 91.417 requires the following additional information to be maintained in the aircraft maintenance records:

Total time in service of the airframe plus each engine and propeller.

Current status of any life-limited parts.

Time since last overhaul of all items required to be overhauled at a specified TBO.

96

cont.

Current inspection status of the aircraft, including the time since the last required inspection.

Current status of applicable Airworthiness Directives, including method of compliance and, for recurring ADs, the time and date when the next action is required.

Copies of all Form 337s required for major alterations (including any items approved via STC, even innocuous ones such as aftermarket strobe lights and sun visors).

976.2.Completing Maintenance Records

( 43.2Records of overhaul and rebuilding.

Information requirements for new documentation or updating of existing documentation are determined to allow for accurate completion of records,

Documentation is completed accurately and clearly to enable information to be easily read or interpreted,

All procedures for storing and distributing documentation are followed to ensure ready access when required in accordance with regulatory and enterprise procedures,98

cont. Information is design to help keep records of entre aircraft in order, simplifying recordkeeping & ensuring compliance with the regulationTo keep records of entire aircraft in order the following done information are needed:Inspection activitiesTests activitiesRepairs activitiesAlternations activitiesAirworthiness directivesService bulletinsEquipment additionsRemovals or exchanges

996.3.Completing Forms

This advisory circular (AC) provides instructions for completing Federal Aviation Administration (FAA) Form 337, Major Repair and Alteration (Airframe, Power plant, Propeller, or Appliance).The form serves two main purposes:(1) To provide aircraft owners and operators with a record of major repairs and major alterations indicating the details and approvals.(2) To provide the FAA with a copy of the form for inclusion in the aircraft records at the FAA Aircraft Registration Branch, AFS-750.This form can be completed on paper or by using the electronic FAA Form 337. Information can be found online at http://eformservice100

6.4. Completing Logs , Tags, & other sheets

The FARs, placed primary responsibility for both maintenance and recordkeeping directly on the shoulders of the aircraft owner, not the mechanic or shop.

"Each owner or operator of an aircraft ... (b) shall ensure that maintenance personnel make appropriate entries in the aircraft maintenance records indicating that the aircraft has been approved for return to service." and FAR 91.407 says:

"(a) No person may operate any aircraft that has undergone maintenance ... unless ... (2) the maintenance record entry required by 43.9 or 43.11, as applicable, of this chapter has been made."

101102

6.5. Storing & Distributing Documentation

Store electronic documents:where they are stored, for how long, migration of the documents, and eventual document destruction.

A published document for distribution has to be in a format that can not be easily altered.

An original master copy of the document is usually never used for distribution other than archiving.

Distributing electronically needs the equipment tasking the job has to be quality endorsed AND validated. Similarly quality endorsed electronic distribution carriers have to be used.

This approach applies to both of the systems by which the document is to be inter-exchanged, if the integrity of the document is highly in demand.

103Cont. ..FAR 91.417 goes on to define how long such maintenance records must be retained by the aircraft owner:Records of maintenance work and inspections performed must be kept until the work is repeated or superseded by other work, or for one year after the work is performed.Records of total times-in-service, times since overhaul, current inspection status, current AD compliance and 337 forms must be retained permanently and transferred with the aircraft when it is sold.If the aircraft flunks an annual or 100-hour inspection and the inspector furnishes the owner a list of defects, that list must be kept until the defects are repaired and the aircraft is approved for return to service.
