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).

# @A340-500/600 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.
