NOTE 1: This EEC software change is not applicable to CFM56-7B dual annularcombustor (DAC) engines.

NOTE 2: This EEC software change is applicable to spare EECs and EECs installedon spare engines.

NOTE 3: Electronic control unit (ECU) and EEC are interchangeable nomenclatureson the CFM56-7B engine and will be referenced as ECU/EEC.

B. Description

This Service Bulletin announces the production introduction and spare partsavailability of FADEC3 software version 7.B.W2F3 P/N 2044M25P19 and FADEC2software version 7.B.W2F2 P/N 1853M78P39 to the CFM56-7B SAC engines.

C. Compliance

Category 2

CFM recommends that you do this Service Bulletin as soon as possible withouteffect on revenue service but before 12 months from the issue date of this ServiceBulletin.

Impact D

This recommendation is to address a condition that may result in a Delay orCancellation (D&C).

NOTE: This Service Bulletin can be accomplished on wing or in shop.

This Service Bulletin is offered to improve the reliability or performance of your GEproduct, or to help prevent the occurrence of the event or condition described in thisService Bulletin.

ENGINE FUEL AND CONTROL - Electronic Control Unit (73-21-60) - New Software Version7.B.W2 for SAC Engines

D. Concurrent Requirements

None.

E. Reason

(1) Objective:

To introduce new ECU/EEC software.

(2) Condition:

To incorporate reliability improvements for the CFM56-7B SAC engine models.

(3) Cause:

EEC software version 7.B.W2 incorporates updates based on revenue serviceexperience.

(4) Improvement:

NOTE: This incremental software revision addresses an issue within7.B.W and 7.B.W1 and also reduces operator burden throughenhancements.

(a) Start Over-fueling Event Mitigation

Address an issue within 7.B.W and 7.B.W1 software that, in rarecircumstances, may result in engine over-fueling during start attempt.

(b) Oil Filter Delta P Switch (OFDPS) Logic Improvement

. Update Disagree Fault 79-x112n to monitor for Close/Close disagreeonly.

. All other monitoring logic remains unchanged. The function of theswitch to detect and indicate a clogged filter at the airplane levelis unchanged.

(c) Remove PMAT NVM Write Requirement during Software Load

. Change the SW loader file included in the production compact disk(CD) to remove command to download EEC NVM when installing7.B.W2 and future software builds.

. Response to operator request to reduce maintenance burdenassociated with software load.

(d) Dual Channel 115VAC Fault Dispatch level Change to "No Dispatch"

Update fault 73-3135n (Dual Channel) from Short Time Dispatch to NoDispatch to be consistent with MMEL.

B. On-Wing ECU/EEC Reprogramming

(1) Refer to Boeing 737-600/700/800/900 AMM, 73-21-60, EEC Software Load.

C. In Shop Reprogramming

(1) Refer to the CFM56 CMM, 73-24-02, CFMI-TP.CM.507 or CFM56 CMM,73-21-75, CFMI-TP.CM.360.

(2) Data retention: Keep all downloaded NVM files as part of the ECU/EEChistory file necessary for repair source substantiation (RSS) testing.

D. Reidentification of the ECU/EEC Software Identification Plate

(1) Use a ballpoint pen to line out the old FADEC software part number (keeplegibility), and write the new software part number and version reference onthe ECU/EEC software identification plate (metallic sticker) on the ECU/EEC:
