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 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.

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.

NOTE: For a full improvements description, refer to modification operational impact No. 55437

and to modification operational impact No. 55438.

New software standard L20 on Flight Control Primary Computer (FCPC) 2K0 and 2K1

was defined in order to improve the elevator monitoring.

(2) Objective/Action

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.

(3) Advantages

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.

SERVICE BULLETIN

- Improvement of the double pressurization logic on the elevator.

- 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.

(4) Operational/Maintenance Consequences

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

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.

NOTE: For a full improvements description, refer to modification operational

impact No. 55437 and to modification operational impact No. 55438.

D. DESCRIPTION

NOTE: To accomplish this Service Bulletin, you have two possibilities :

- either you modify the three FCPCs by replacement or reprogramming of

their OBRMs as described in TASK 274144-831-801 001 Modification of

the three FCPCs by Replacement or Reprogramming of their OBRMs.

- or you replace them as described in TASK 274144-831-802 001

Modification by Replacement of the three FCPCs.
