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 software standard L19 on Flight Control Primary Computer (FCPC) 2K2 hardware was defined in

order to take into account the last FCPC software evolutions.

This Service Bulletin is published to advise all operators of A340 aircraft of the issue of AIRBUS

FRANCE S.A.S..LA2K2-27-008. This Service Bulletin consists in introducing new software standard

"L19" on FCPC hardware 2K2 by means of On Board Replaceable Module (OBRM) on the three

FCPCs.

Accomplishment of this Service Bulletin introduces the following modifications:

- New elevator position monitoring,

- Improvement of the monitoring of the Flight Control Computer pushbutton switches,

- Improvement of monitoring to detect a Trimmable Horizontal Stabilizer Actuator (THSA) manual

command jamming,

- Improvement of the double pressurization logic on elevator,

- New monitoring to avoid mixability between FCPC different standards,

SUMMARY

- Correction of the spurious ECAM warning "F/CTL PRIM x FAULT" due to DGO FIFO FULL issue

(TFU 27.93.00.046),

- Use of an estimated true airspeed when temperature probes are inoperative,

- Introduction of the speed/angle of attack estimation and monitoring,

- Extension to basic aircraft of "air brakes extension in conf 3 and full" logic

The operational maintenance consequences of this Service Bulletin are: modification of the Flight Crew

Operating Manual (FCOM) (Refer to FCOM Vol. 1) and (Refer to FCOM Vol. 3)

- modification of the Flight Crew Operating Manual (FCOM) (Refer to FCOM Vol. 1) and (Refer to

FCOM Vol. 3)

- This Service Bulletin associated with Service Bulletin No.A340-27-4146 which introduces FCSC

standard L19/M18 P/N LA2B00300A40000 (Mod.55697S18547), cancels Operations Engineering

Bulletin No. 54. Operators having programmed an OEB reminder should delete the reminder(s)

from their system.

NOTE: FCPC L19 standard with hardware 2K2 has been developed for enhanced aircraft

(aircraft with electrical rudder - Mod.49144S16279) but can also be installed on basic

aircraft (aircraft with mechanical rudder).

WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE

CAUTIONS INCLUDED IN THE REFERENCED PROCEDURES

CAUTION: ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP

ELECTRICAL WIRING IN A SATISFACTORY CONDITION (ELECTRICALLY

AND MECHANICALLY SERVICEABLE). WHEN YOU DO MAINTENANCE

WORK, REPAIRS OR MODIFICATIONS, ALWAYS KEEP ELECTRICAL

WIRING, COMPONENTS AND THE WORK AREA AS CLEAN AS

POSSIBLE. TO DO THIS:

- PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC.

AS NECESSARY ON WIRING AND COMPONENTS

- REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL AND

OTHER CONTAMINATION.

THESE PRECAUTIONS WILL DECREASE THE RISK OF

CONTAMINATION AND DAMAGE TO THE ELECTRICAL WIRING
