### TITLE: FLIGHT CONTROLS - ELECTRICAL BACK-UP - INSTALL NEW BACKUP CONTROL MODULE (BCM) ON ENHANCED A330. **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 58118S30423 MINOR None 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 During BCM (Back-up Control Module) retrofit as per Airbus SB Ref. A330-27-3142 and SAGEM Service Bulletin 418-27-010 introducing BCM PN 418-00877-102 (replacement of corroded resistances at SAGEM facilities), some attachment screws of the internal gyrometer have been found loosened within the equipment. A loose attachment of the gyrometer may induce erroneous yaw data leading to a degradation of the piloting laws when the aircraft is in back up control configuration. Investigations performed at manufacturer’s facility pointed out that screws loosening on BCM Part Number (P/N) 418-00877-100, 418-00877-101 and 418-00877-102 are due to temperature variations combined with vibrations. This scenario is only considered for aircraft with electrical rudder (post-mod 49144). This Service Bulletin is published to advise all operators of A330 enhanced aircraft fitted with electrical rudder (post-mod 49144) of the issue of SAGEM Service Bulletin No. 418-27-011. The design solution uses a positive locking device for the fixation of the gyrometer and additional locking washers for the attachment of the electronic card. These improvements under supplier responsibility (SAGEM) lead to introduce a new BCM PN 418-00877-103 amendment A. Accomplishment of this Service Bulletin will contribute to ensure the reliability of the yaw data provided by the BCM. This Service Bulletin will cancel AD 2009-0153 if associated with the modification of Pedal Feel and Trim Unit (Ref OIT SE 999.0058/09/LB). Only in case of this association, aircraft dispatch with FCPC3 (PRIM 3) inoperative (MMEL 27-93-01-C) for A330-200/300 aircraft fitted with MOD 49144 will be restored.

# @A330 SERVICE BULLETIN

B. CONCURRENT REQUIREMENTS Accomplishment of this Service Bulletin requires the prior or simultaneous accomplishment of the following Service Bulletin(s) or the equivalent production modification(s): Service Bulletin No. A330-27-3142 Mod. No. 55185S18591 C. REASON (1) History During BCM (Back-up Control Module) retrofit as per Airbus SB Ref. A330-27-3142 and SAGEM Service Bulletin 418-27-010 introducing BCM PN 418-00877-102 (replacement of corroded resistances at SAGEM facilities), some attachment screws of the internal gyrometer have been found loosened within the equipment. A loose attachment of the gyrometer may induce erroneous yaw data leading to a degradation of the piloting laws when the aircraft is in back up control configuration. Investigations performed at manufacturer’s facility pointed out that screws loosening on BCM Part Number (P/N) 418-00877-100, 418-00877-101 and 418-00877-102 are due to temperature variations combined with vibrations. This scenario is only considered for aircraft with electrical rudder (post-mod 49144). (2) Objective/Action This Service Bulletin is published to advise all operators of A330 enhanced aircraft fitted with electrical rudder (post-mod 49144) of the issue of SAGEM Service Bulletin No. 418-27-011. The design solution uses a positive locking device for the fixation of the gyrometer and additional locking washers for the attachment of the electronic card. These improvements under supplier responsibility (SAGEM) lead to introduce a new BCM PN 418-00877-103 amendment A. (3) Advantages Accomplishment of this Service Bulletin will contribute to ensure the reliability of the yaw data provided by the BCM. (4) Operational/Maintenance Consequences This Service Bulletin will cancel AD 2009-0153 if associated with the modification of Pedal Feel and Trim Unit (Ref OIT SE 999.0058/09/LB). Only in case of this association, aircraft dispatch with FCPC3 (PRIM 3) inoperative (MMEL 27-93-01-C) for A330-200/300 aircraft fitted with MOD 49144 will be restored. D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : Task 273161-831-801-001: Modification (1) Remove the Back-up Control Module 42CS (2) Modify the Back-up Control Module 42CS

# @A330 SERVICE BULLETIN (3) Install the Back-up Control Module 42CS E. COMPLIANCE (1) Classification RECOMMENDED (2) Accomplishment Timescale Accomplishment of this Service Bulletin is recommended at the earliest opportunity where manpower and facilities are available. F. APPROVAL Approved under EASA Design Organisation Approval No. EASA21J.031.
