MODIFICATIONS 

As per EASA lR 21, a minor change is one that 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 A340-200f300 Thrust Reversers (T/R) system has experienced an increased number of REVUNLOCK warnings. The investigation into the root cause concluded that the T/R pivoting door actuator 

did not have sufficient stroke margin to fully engage the primary lock under some conditions. 

The following contributors are suspected to have a detrimental impact on the actuator stroke margin: 

Low T/R structural stiffness 

Incorrect rigging of a pivoting door 

Component wear (as gimbal gap). 

Temperature component and high duct pressure during pivoting door closure. 

Also, two cases of in-flight single pivoting door deployment have occurred, during aircraft climb, in 

which the primary lock and secondary lock disengaged. Secondary lock disengagement is a result of 

dynamic loading, which may occur during high·powered rev-unlock events. High-powered rev-unlock 

evenls may occur during take off, climb or in flight.

SERVICE BULLETIN 

SUMMARY 

This Service Bulletin is published to advise all operators 01 A340-200/300 aircraft model 01 the issue of 

CFM Service Bulletin No. 78-0091. 

Accomplishment 01 this Service Bulletin will : 

Address a primary root cause of T1R unlock events. 

Prevenllhe occurrence of a single door in f1ight deployment in case of primary lock failure. 

Accomplishment of this Service Bulletin consists in installing the new actuator on 10 thrust reverser 

actuation system doors. 

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

repercussion in case 01 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. 

Installation of an increased stroke actuator will provide the system with enough stroke margin to ensure 

that the pivoting door is successfully pulled to the closed position where Ihe T/R can (e-Iock correctly. 

The new actuator provides additional stroke margin at door closure in order to compensate all stroke 

margins consumers identified during root causes investigations (structure stiffness wear and gimbal 

gap, temperature effecL). 

The secondary lock, within the new actuator, has been redesigned to sustain potential dynamic load. 

In order to help operators to manage the different configurations which will follow this Service Bulietin 

embodiment, a specific red placard to be installed on each T/R cowl forward 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 A340-78-4037 will improve the reliability of 

the thrust reverser locking mechanism.

C. REASON 

(1) History 

The A340-200!300 Thrust Reversers (T/R) system has experienced an increased 

number of REV-UNLOCK warnings. The investigation into the rool cause concluded that 

the T/R pivoting door actuator did nol have sufficient stroke margin to fully engage the 

primary lock under some conditions . 

The following contributors are suspected to have a detrimental impact on the actuator 

stroke margin : 

Low T/R structural stiffness 

Incorrect rigging 01 a pivoting door 

Component wear (as gimbal gap). 

Temperature component and high ducl pressure during pivoting door closure. 

Also, two cases 01 in· flight single pivoting door deployment have occurred, during aircraft 

climb. in which the primary lock and secondary lock disengaged. Secondary lock 

disengagement is a resull of dynamic loading, which may occur during high-powered 

rev-unlock events. High-powered rey-unlock events may occur during take of!. climb or 

in flighl. 

(2) Objective/Action 

This Service Bulletin is published to advise all operalors of A340-200/300 aircraft model 

of the issue of CFM Service Bulletin No. 78·0091. 

Accomplishment 01 this Service Bulletin will : 

Address a primary root cause of T/R unlock events. 

Prevent the occurrence of a single door in flight deployment in case of primary lock 

failure. 

Accomplishment of Ihis Service 8ulletin consists in installing the new actuator on 10 

thrust reverser actuation system doors. 

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

significant repercussion in case of untimely deployment close 10 the ground.

SERVICE BULLETIN 

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

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

Installation of an increased stroke actuator will provide the system with enough stroke 

margin to ensure that the pivoting door is successfully pulled to the closed position 

where the T/R can re-Iock correctly. 

The new actuator provides additional stroke margin at door closure in order to 

compensate all stroke margins consumers identified during root causes investigations 

(structure stiffness wear and gimbal gap. temperature e!fecL.). 

The secondary lock, within the new actuator, has been redesigned to sustain potential 

dynamic load. 

In order to help operators \0 manage the different configurations which will follow this 

Service Bulletin embodiment, a specific red placard to be installed on each TIA cowl 

lorward frame, will detail the parts required depending on the thrust-reverser pivotingdOOf location on the aircraft. For further information, please refer to TFU 78.30.00.052.
