### TITLE: FLIGHT CONTROLS - FCPC - INTRODUCE FCPC L22A 2K1 OR FCPC L22A 2K0 FOR A340-200/300 BASIC A/C WITH MECHANICAL RUDDER **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 55437S18647 55438S18648 201689S31875 201690S31876 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 New Flight Control Primary Computer (FCPC) standards L22A 2K0 and L22A 2K1 are developed to cover the improvement of Flight Guidance and Envelope (FGE) behaviour in some conditions of FCPC in alternate law. It implies to replace the current FCPC standard L20 2K1 PN LA2K1A100290000 by new ones, FCPC standard L22A 2K1 PN LA2K1A1002B0000, electrically and mechanically interchangeable and to replace the current FCPC standard L20 2K0 PN LA2K01500290000 by new ones, FCPC standard L22A 2K0 PN LA2K015002B0000, electrically and mechanically interchangeable. Replace associated OBRM PN LA2K01500290400 by new one PN LA2K015002B0400. Replace associated OBRM PN LA2K1A100290400 by new one PN LA2K1A1002B0400. Main improvements introduced by L22A 2K0 and L22A 2K1 Standard : - Reduction of High Vertical Speed (VZ) at touchdown with new parameters recording in the DFDR (Digital Flight Data Recorder), - Improvement of aircraft behaviour in case of erratic Air Data/Inertial Reference Unit (ADIRU) outputs,

(3) Advantages Main improvements introduced by L22A 2K0 and L22A 2K1 Standard : - Reduction of High Vertical Speed (VZ) at touchdown with new parameters recording in the DFDR (Digital Flight Data Recorder), - 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 GS and PLD logics (ground spoiler and partial lift damping), - Improvement of aircraft behaviour in case of two consistently erroneous AOA (Angle Of Attack) information : limitation of Trimmable Horizontal Stabilizer (THS) at pitch up, - Maximum Operating Speed/Maximum Operating Mach (VMO/MMO) and autopilot disconnection logic (A340-300 only), - Autopilot inhibition engagement under unreliable airspeed condition. (4) Operational/Maintenance Consequences Accomplishment of this Service Bulletin will cancel the OEB 35 (formerly OEB 95 up until 2011) and the Airplane Flight Manual (AFM) TR 150 according to Airworthiness Directive No. 2010-0271. Accomplishment of this Service Bulletin will also cancel the OEB 40 (formerly OEB 88 up until 2011).
