### TITLE: FLIGHT CONTROLS - FCPC - INTRODUCE NEW FCPC STD L21A 2K2 ON A340 AIRCRAFT FAMILY **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 200356S30851 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 When there are significant differences between all airspeed sources, the flight controls revert to alternate law, the autopilot (AP) and the autothrust (A/THR) automatically disconnect, and the Flight Directors (FD) bars are automatically removed. It has been identified that, after such an event, if two airspeed sources become similar while still erroneous, the flight guidance computers: - Display FD bars again, - Enable autopilot and auto thrust re-engagement. To address this aircraft behaviour, operational recommendations were issued beginning of January 2011 in red OEB 35 (formely OEB 95/1 up until 2011) and its associated OEB PROC 35 (formely OEB 95/1 up until 2011) in the Quick Reference Handbook (QRH). New software standard L21A on FCPC 2K2 hardware has been defined to take into account the last FCPC software evolution: - Autopilot inhibition under unreliable airspeed condition. - Correction of the spurious Electronic Centralized Aircraft Monitoring (ECAM) warning "F/CTL RUD X SERVO FAULT" at engine start or engine shut down (TFU 27.24.00.009),

# @A340 SERVICE BULLETIN SUMMARY - Reduction of high Vertical Speed (VZ) at touchdown with new parameters recording in the Digital Flight Data Recorder (DFDR) (A340-300 only), - Improvement of aircraft behaviour in case of erratic Air Data/Inertial Reference Unit (ADIRU) outputs, - Improvement of the reconfiguration logics in case of electrical transients during rotation at take off (TFU 27.90.00.035), - Improvement of the Ground Spoiler and Partial Lift Damping (GS and PLD) logics, - Maximum operating speed/ Maximum Operating Mach (VMO/MMO) and Autopilot (AP) disconnect logic (A340-300 only), - Improvement of aircraft behaviour in case of two consistently erroneous Angle Of Attack (AOA) information: limitation of Trimmable Horizontal Stabilizer (THS) at pitchup. This Service Bulletin is published to advise all operators of A340 aircraft of the issue of Vendor AIRBUS OPERATIONS S.A.S. Service Bulletin No. LA2K2-27-012

. This Service Bulletin recommends either replacing the existing FCPCs with hardware 2K2 by FCPCs with hardware 2K2 and new standard L21A, or modifying the existing FCPCs with hardware 2K2 into new standard L21A by means of On-Board Replaceable Modules (OBRMs) as per Vendor AIRBUS OPERATIONS S.A.S. Service Bulletin No. LA2K2-27-012

. Accomplishment of this Service Bulletin allow the possibility for aircraft on which standard L20 2K0 or L20 2K1 are installed to upgrade to L21A2K2 standard as per replacement by Aircraft Maintenance Manual (AMM). New Flight Control Primary Computer (FCPC) standards have been developed in order to inhibit autopilot engagement under unreliable airspeed condition in the here above situation described in FOT Ref. 999.0112/10 dated on 20 December 2010. Accomplishment of this Service Bulletin will cancel the red OEB 35 (formely OEB 95/1 up until 2011) and therefore also the Airplane Flight Manual (AFM) TR 150 according to the Airworthiness Directive No. 2010-0271. Accomplishment of this Service Bulletin will also cancel the OEB 40 (formely OEB 88/4 up until 2011) and Flight Manual (FM) 4.02.00/54 mandated by EASA Airworthiness Directive No. 2009-0012E.

# @A340 SERVICE BULLETIN - Enable autopilot and auto thrust re-engagement. To address this aircraft behaviour, operational recommendations were issued beginning of January 2011 in red OEB 35 (formely OEB 95/1 up until 2011) and its associated OEB PROC 35 (formely OEB 95/1 up until 2011) in the Quick Reference Handbook (QRH). New software standard L21A on FCPC 2K2 hardware has been defined to take into account the last FCPC software evolution: - Autopilot inhibition under unreliable airspeed condition. - Correction of the spurious Electronic Centralized Aircraft Monitoring (ECAM) warning "F/CTL RUD X SERVO FAULT" at engine start or engine shut down (TFU 27.24.00.009), - Reduction of high Vertical Speed (VZ) at touchdown with new parameters recording in the Digital Flight Data Recorder (DFDR) (A340-300 only), - Improvement of aircraft behaviour in case of erratic Air Data/Inertial Reference Unit (ADIRU) outputs, - Improvement of the reconfiguration logics in case of electrical transients during rotation at take off (TFU 27.90.00.035), - Improvement of the Ground Spoiler and Partial Lift Damping (GS and PLD) logics, - Maximum operating speed/ Maximum Operating Mach (VMO/MMO) and Autopilot (AP) disconnect logic (A340-300 only), - Improvement of aircraft behaviour in case of two consistently erroneous Angle Of Attack (AOA) information: limitation of Trimmable Horizontal Stabilizer (THS) at pitchup. (2) Objective/Action This Service Bulletin is published to advise all operators of A340 aircraft of the issue of Vendor AIRBUS OPERATIONS S.A.S. Service Bulletin No. LA2K2-27-012

. This Service Bulletin recommends either replacing the existing FCPCs with hardware 2K2 by FCPCs with hardware 2K2 and new standard L21A, or modifying the existing FCPCs with hardware 2K2 into new standard L21A by means of On-Board Replaceable Modules (OBRMs) as per Vendor AIRBUS OPERATIONS S.A.S. Service Bulletin No. LA2K2-27-012

. Accomplishment of this Service Bulletin allow the possibility for aircraft on which standard L20 2K0 or L20 2K1 are installed to upgrade to L21A2K2 standard as per replacement by Aircraft Maintenance Manual (AMM). (3) Advantages New Flight Control Primary Computer (FCPC) standards have been developed in order to inhibit autopilot engagement under unreliable airspeed condition in the here above situation described in FOT Ref. 999.0112/10 dated on 20 December 2010.
