NOTE: As per EASA IR 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

Further to some reported cases of abnormal rudder deflections during application of the following tests :

- AMM Task 27-99-00-740-801 Operational test of the Backup Control Module (BCM) and Back-Up

Power Supply (BPS) by Built-In Test Equipment (BITE).

or

- AMM Task 27-99-00-710-801 Operational test of the rudder electrical back-up

It was detected that an erroneous pedals’ order could be sent by the Pedal Feel and Trim Unit (PFTU)

to the BCM.

The root cause was a broken screw inside the PFTU, involving that the link between the Rotary

Variable differential transducer (RVDT) providing pedals’ position to the BCM and the input shaft was

lost and RVDT could turn on its axis.

Investigations performed at manufacturer’s facility pointed out that screws rupture on PFTU Part

Number (P/N) 6259-1 and 6259-2 is due to weakening of the screws following bad degasification after

surface treatment during manufacturing process. This scenario is only considered for aircraft with

electrical rudder (post-Mod. No. 49144S16279 (INSTALL RUDDER FLY-BY WIRE ON A330/A340).

SERVICE BULLETIN

SUMMARY

This Service Bulletin is published to advise operators of A340-500/600 aircraft of the issue of SAGEM

Service Bulletin No. 6259-27-006.

The design solution consists in a new grade of screws more robust and addition of self-locking inserts

for the fixation of the RVDT on the input shaft. These improvements under supplier responsibility

(SAGEM) lead to introduce a new PFTU P/N 6259-0311.

This Service Bulletin requires modifying or replacing the affected PFTU :

- P/N 6259-1 replaced by P/N 6259-0311 (CONF 001)

or

- P/N 6259-2 modified into P/N 6259-0311 (CONF 002).

Accomplishment of this Service Bulletin will improve the reliability of the PFTU.

Aircraft dispatch with FCPC3 (PRIM 3) inoperative (MMEL 27-93-01-C) will be restored on

A340-500/600 with PFTU post Mod. No. 200667S31517.

SERVICE BULLETIN

Investigations performed at manufacturer’s facility pointed out that screws rupture on

PFTU Part Number (P/N) 6259-1 and 6259-2 is due to weakening of the screws

following bad degasification after surface treatment during manufacturing process.

This scenario is only considered for aircraft with electrical rudder (post-Mod. No.

E. COMPLIANCE

(1) Classification

MANDATORY: Service Bulletin must be accomplished.

(2) Accomplishment Timescale

Accomplishment of this Service Bulletin is expected to be rendered mandatory by the

issue of an Airworthiness Directive (AD) published by the European Aviation Safety

Agency (EASA). The accomplishment timescale, which has not yet been defined, will be

given in the AD.

F. APPROVAL

Approved under EASA Design Organisation Approval No. EASA 21J.031.

If an aircraft listed in the effectivity has a modification or repair embodied that is not of

AIRBUS origin, and which affects the content of this Service Bulletin, the operator is

responsible for obtaining approval by its airworthiness authority for any adaptation necessary

before incorporation of the Service Bulletin.

G. MANPOWER

The manpower estimates given in this Service Bulletin are based on the direct labor cost to

do the work. These estimates assume that the work will be done by experienced personnel,

and may need to be revised upwards to suit operator’s circumstances. The estimates do not

include the time to prepare, plan or inspect the work. Manufacture and procurement of parts

and tools, drying times for paints, sealants, etc., and general administration work are also not

included.
