### TITLE: FLIGHT CONTROLS - FCSC - INTRODUCE FCSC L20M19 STANDARD ON BASIC A340 AIRCRAFT. **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 55696S18546 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 A new Flight Control Secondary Computer (FCSC) standard, named L20M19, was developed to take into account the last FCSC software evolutions. This Service Bulletin is published to advise all operators of A340 aircraft with mechanical rudder (aircraft on which Mod. No. 49144S16279 (FLIGHT CONTROLS - ELECTRICAL FLIGHT CONTROL SYSTEM (EFCS) - INSTALL RUDDER FLY-BY WIRE ON A330/A340) is not embodied) of the issue of THALES AVIONICS Service Bulletin No. B492AAM-27-014. This Service Bulletin recommends introduction of new software "L20M19" PN B492AAM0411 on the two FCSCs by means of On-Board Replaceable Modules (OBRMs) replacement or reprogramming or FCSCs replacement. Accomplishment of this Service Bulletin introduces the following improvements : - new elevator position monitoring, - improvement of other computers monitoring, - improvement of rate gyro units monitoring. The "new elevator position monitoring" function, that will allow to cancel red Operation Engineering Bulletin (OEB) No. 54, will be active at aircraft level only if FCSC standard L20M19 standard is associated with future Flight Control Primary Computer (FCPC) standards. It is anticipated that an Airworthiness Directive (AD) will mandate modification of both FCSC and FCPC. DATE: Dec 16/08 SERVICE BULLETIN No.: A340-27-4145 REVISION No.: 00 - Dec 16/08 Page: 1 5
