### TITLE: FLIGHT CONTROLS -FLIGHT CONTROL PRIMARY COMPUTER (FCPC)- INTRODUCE NEW FCPC STD W12 ON A340-500/600 AIRCRAFT. **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 200358S19548 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 standard W12 on Flight Control Primary Computer (FCPC) 2K2 hardware has been defined mainly in order to prevent aircraft abnormal behavior in case of erratic Air Data/Inertial Reference Unit (ADIRU) outputs. This Service Bulletin is published to advise all operators of A340/500-600 aircraft of the issue of AIRBUS OPERATIONS S.A.S. Service Bulletin No. LA2K2-27-013. This Service Bulletin recommends either replacing the existing FCPCs with hardware 2K2 by FCPCs with hardware 2K2 and new standard W12, or modifying the existing FCPCs with hardware 2K2 into new standard W12 by means of On-Board Replaceable Modules (OBRMs) as per AIRBUS OPERATIONS S.A.S. Service Bulletin No. LA2K2-27-013. New software standard W12 on FCPC 2K2 hardware has been defined to take into account the last FCPC software evolutions. The main FCPC improvements are: - Improvement of aircraft behavior in case of erratic ADIRU outputs. - Improvement of the Ground Spoiler (GS) and Partial Lift Damping (PLD) logics. - Improvement of aircraft behavior in case of two consistently erroneous Angle Of Attack (AOA) information: limitation of Trimmable Horizontal Stabilizer (THS) at pitch up.
