All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES New software standard L20 on Flight Control Primary Computer (FCPC) 2K0 and 2K1 was defined in order to improve the elevator monitoring. This Service Bulletin is published to advise all operators of A340 aircraft of the issue of AIRBUS FRANCE S.A.S. Service Bulletins No. LA2K0-27-020 and LA2K1-27-012. This Service Bulletin consists in introducing new software standard "L20" on the three FCPCs hardware 2K1 or 2K0 by means of On Board Replaceable Module (OBRM) replacement or reprogramming or FCPCs replacement. Accomplishment of this Service Bulletin introduces the following modifications in L20 standards : - Improvement of the elevator position monitoring. - Improvement of the monitoring of the flight control computer pushbutton switches. - Improvement of the monitoring to detect jamming of the Trimmable Horizontal Stabilizer (THS) actuator manual command. - Improvement of the double pressurization logic on the elevator.

# @A340 SERVICE BULLETIN SUMMARY - New monitoring to avoid mixability between different FCPC standards. - Modification for aircraft with mechanical rudder to allow speed brake extension with flaps fully extended. - Tail strike protection at take off. The operational consequences of this Service Bulletin are the modification of the Flight Crew Operating Manual (FCOM) Vol. 1 and 3. The "new elevator position monitoring" function, that allow to cancel red Operations Engineering Bulletin (OEB) No. 54, will be active at aircraft level only if Mod. No. 55696S18546 (FLIGHT CONTROLS - FCSC - INTRODUCE FCSC STD L20M19 FOR IN-SERVICE AIRCRAFT (Service Bulletin No. A340-27-4145)) or Mod. No. 55697S18547 (FLIGHT CONTROLS - FCSC - INTRODUCE FCSC STD L19M18 ON LR ENHANCED A/C (Service Bulletin No. A340-27-4146)) is associated with FCPC standard L20 2K0 or L20 2K1. It is anticipated that an Airworthiness Directive (AD) will be issued to allow cancellation of this OEB No. 54. After AD issuance, this Service Bulletin will cancel red OEB No. 54 and Aircraft Flight Manual (AFM) Temporary Revision (TR) No. 4.02.00/25 if associated with FCSC L20M19 (Service Bulletin No. A340-27-4145) or with FCSC L19M18 (Service Bulletin No. A340-27-4146). Operators having programmed an OEB reminder should delete the reminder(s) from their system. This Service Bulletin has for operational consequences the modification of the Flight Manual (FM) only in case of FCPC/FCSC associations described above.
