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 standard of Flight Control Primary Computer (FCPC) has been developed to improve aircraft
behavior in case of undetected erroneous Radio Altitude (RA) information.
This Service Bulletin replaces FCPC standard W12 with new FCPC standard W13, and advises all
operators of A340-500/600 aircraft of the issue of AIRBUS OPERATIONS S.A.S. Service Bulletin No.
LA2K2-27-019.
To accomplish this Service Bulletin, you have three possibilities, as FCPC upgrade can be done either:
- by replacement of the FCPCs on aircraft,
- by replacement of associated On Board Replaceable Module (OBRM) set (composed of PN
LA2K2B100GD0100 & LA2K2B100GD0200 installed through Modification No. 200358S19548) on
aircraft,
- by replacement or reprogramming OBRM as per AIRBUS OPERATIONS S.A.S. Service Bulletin
No. LA2K2-27-019 on bench.
Accomplishment of this Service Bulletin will bring the following improvements:

SERVICE BULLETIN
SUMMARY
- Improvement of aircraft behavior in case of undetected erroneous RA information linked to red
Operations Engineering Bulletin OEB No. 26 (formerly OEB 91 up until 2011),
- New monitoring to detect frozen Angle Of Attack (AOA) probe,
- New monitoring to detect a bent AOA probe.
The operational consequences of this Service Bulletin are modification of:
- Flight Crew Operating Manual (FCOM),
- Quick Reference Hand Book (QRH),
- Flight Manual (FM),
- Master Minimum Equipment List (MMEL).
Accomplishment of this Service Bulletin cancels the requirements of the red Operations Engineering
Bulletin (OEB) No. 26 (formerly A340 OEB91 until 2011) and AFM TR38 while introducing the white
OEB No. 48 when none of the following Flight Management Guidance Envelope Computer (FMGEC) is
installed (which are the minimum FMGEC standards necessary to cancel white OEB 48):
- FMGEC P4K2 (Modification No. 202095S31698 ), T5AK2 (Modification No. 202844S19543 ), P3E9
(Modification No. 202863S32291 ), T5E9 (Modification No. 203035S32290).
This Service Bulletin has an impact on flight operations documentation; refer to AirbusWorld to consult
the Modification Operational Impact (MOI) No. 204125 described in Technical Follow-up (TFU)

- by replacement of associated On Board Replaceable Module (OBRM) set
(composed of PN LA2K2B100GD0100 & LA2K2B100GD0200 installed through
Modification No. 200358S19548) on aircraft,
- by replacement or reprogramming OBRM as per AIRBUS OPERATIONS S.A.S.
Service Bulletin No. LA2K2-27-019 on bench.
(3) Advantages
Accomplishment of this Service Bulletin will bring the following improvements:
- Improvement of aircraft behavior in case of undetected erroneous RA information
linked to red Operations Engineering Bulletin OEB No. 26 (formerly OEB 91 up until
2011),
- New monitoring to detect frozen Angle Of Attack (AOA) probe,
- New monitoring to detect a bent AOA probe.
(4) Operational/Maintenance Consequences
The operational consequences of this Service Bulletin are modification of:
- Flight Crew Operating Manual (FCOM),
- Quick Reference Hand Book (QRH),
- Flight Manual (FM),
- Master Minimum Equipment List (MMEL).
Accomplishment of this Service Bulletin cancels the requirements of the red Operations
Engineering Bulletin (OEB) No. 26 (formerly A340 OEB91 until 2011) and AFM TR38
while introducing the white OEB No. 48 when none of the following Flight Management
Guidance Envelope Computer (FMGEC) is installed (which are the minimum FMGEC
standards necessary to cancel white OEB 48):
- FMGEC P4K2 (Modification No. 202095S31698 ), T5AK2 (Modification No.
202844S19543 ), P3E9 (Modification No. 202863S32291 ), T5E9 (Modification No.
203035S32290).
This Service Bulletin has an impact on flight operations documentation; refer to
AirbusWorld to consult the Modification Operational Impact (MOI) No. 204125 described
in Technical Follow-up (TFU) 27.00.00.108.

E. COMPLIANCE
(1) Classification
MANDATORY: Service Bulletin must be accomplished.
(2) Accomplishment Timescale
This Service Bulletin has been classified Mandatory by the issue of an Airworthiness
Directive (AD) published by the European Av iation Safety Agenc y (EASA). The AD must
be used as the reference document for the mandated accomplishment timescale.

Organisation Approval No. EASA.21J.031.
If an aircraft listed in the effectivity has a modification or repair embodied that is not of
AIRBUS origin, and which affects the content of this Service Bulletin, the operator is
responsible for obtaining approval by its airworthiness authority for any adaptation necessary
before incorporation of the Service Bulletin.
G. MANPOWER
The manpower estimates given in this Service Bulletin are based on the direct labor cost to
do the work. These estimates assume that the work will be done by experienced personnel,
and may need to be revised upwards to suit operator’s circumstances. The estimates do not
include the time to prepare, plan or inspect the work. Manufacture and procurement of parts
and tools, drying times for paints, sealants, etc., and general administration work are also not
included.
