As per EASA IR 21. a minor change is one thai has no appreciable effect on the 

mass. balance. structural strength, reliability. operational characteristics affecting the 

airworthiness of the product All other changes are major changes. 

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES 

The A340-200/300 thrust reverser system has experienced an increased number of REV-UNLOCK 

warnings. The invesligation into the root cause concluded that the thrust reverser pivoting door primary 

lock can fail to fully engage under some conditions. Full engagement of the primary lock requires the 

locking lever arm 10 move into the correct resting posilion behind the lock cam. 

The locking lever restoring torque may degrade as a result of pivot bearing contamination and 

subsequently calise th e lock nol to engage properly. Improper engagement 01 the primary lock can 

result in a REV UNLOCK warning event. 

Moreover, the primary lock cam may fail in some lunited cases due to fatigue resulting also in a REV 

UNLOCK warning event. 

The lailure 01 pivoting door primary lock combined with secondary lock malfunction may result in a 

thrust reverser door in flight deployment event. 

This Service Bulletin is issued to advise all operators of A340-200/300 aircraft powered by CFM56-C

SUMMARY 

eliminating restoring torque loss due to contamination. 

Improving locking performance. 

Reducing the impact of potential return hydraulic spikes. 

Eliminating the potential for cam failure . 

Accomplishment 01 this Service Bulletin consists in installing the new primary lock on 10 thrust reverser 

actuation system doors. 

Selected doors. for retrofit only. have been shown through fl ight and simulator tests with significant 

repercussion in case 01 untimely deployment dose to the ground. 

The 10 doors for which this S8 applies are: 

Outer engines 11 and 4) : all 4 doors of each engine. 

Inner engines (2 and 3) : upper inboard door of each engine. 

The new primary lock lever arm bearings are sealed and greased to make sure that contamination can 

not affect the locking lever arm restoring torque. 

The locking tever arm torque springs have an increased torque value which will improve locking 

capability. 

The new primary lock design includes a more robust cam design with improved fatigue behaviour. 

There is also a new valve spring whicll provides additional protection against potential hydraulic spikes 

in the reiurn system. 

In order to help operators 10 manage tile different configurations which will follow this Service Bulletin 

embodiment. a specific red placard to be installed on each T/R cowl rorward frame, will detail the parts 

required depending on the thrust· reverser pivoting·door location on the aircraft. For further information. 

please refer to TFU 78.30.00.052. 

Accomplishment of this Service Bulletin and Service Bulletin 78-4038 will improve the reliability of the 

thrust reverser locking mechanism.

C. REASON 

(1) History 

The A340 -200/300 thrust reverser system has experienced an increased Ilumber or 

REV· UNLOCK warnings . The investigation into the root cause concluded that the thrust 

reverser pivoting door primary lock can fail to fully engage under some conditions. Full 

engagement of the primary lock requires the locking lever arm to move into the correct 

resting position behind the lock cam. 

The locking lever restoring torque may degrade as a result of pivot bearing 

contamination and subsequently cause the lock not to engage properly. Improper 

engagement 01 the primary lock can result in a REV UNLOCK warning even!. 

Moreover, the primary lock cam may fail in some limited cases due to fatigue resulting 

also in a REV UNLOCK warning event. 

The failure 01 pivoting door primary lock combined with secondary lock malfunction may 

result in a thrust reverser door in fl ight deployment event 

(2) Objective/Action 

This Service Bulletin is issued to advise all operators of A340-200/300 aircraft powered 

by CFM56-C engines of the issue of CFM Service Bulletin No.CFM56-5C 78-0092. 

Accomplishment of Ihis Service Bulletin consists in . 

eliminating restoring torque loss due to contamination. 

Improving locking performance.

SERVICE BULLETIN 

Accomplishment of this Service Bulletin consists in installing the new primary tock on 10 

thrust reverser actuation system doors. 

Selected doors, for retrofit only, have been shown through flight and simulator tests with 

significant repercussion in case of untimely deployment close to the ground. 

The 10 doors lor which this S8 applies are : 

Outer engines (1 and 4) : all 4 doors of each engine. 

Inner engines (2 and 3) : upper inboard door of each engine. 

The new primary lock lever arm bearings are sealed and greased 10 make sure Ihal 

contamination can not affect the locking lever arm restoring torque. 

The locking lever arm torque springs have an increased torque value which will improve 

locking capability. 

Tbe new primary lock design includes a more robust cam design with improved fatigue 

behaviour. 

There is also a new valve spring which provides additional protection against potential 

hydraulic spikes in the return system. 

In order to help operators 10 manage tile diHerent configurations which wilt follow this 

Service Bulletin embodiment, a specific red ptacard to be installed on each TiA cowl 

forward frame. wilt delail the parts required depending on the thrust-reverser pivoting -

door location on the aircraft. For further information, please refer to TFU 78.30.00.052.
