New Flight Control Primary Computer (FCPC) standards L22A 2K0 and L22A 2K1 are developed to
cover the improvement of Flight Guidance and Envelope (FGE) behaviour in some conditions of FCPC
in alternate law.
It implies to replace the current FCPC standard L20 2K1 PN LA2K1A100290000 by new ones, FCPC
standard L22A 2K1 PN LA2K1A1002B0000, electrically and mechanically interchangeable and to
replace the current FCPC standard L20 2K0 PN LA2K01500290000 by new ones, FCPC standard L22A
2K0 PN LA2K015002B0000, electrically and mechanically interchangeable.
Replace associated OBRM PN LA2K01500290400 by new one PN LA2K015002B0400.

SERVICE BULLETIN
C. REASON
(1) History
New Flight Control Primary Computer (FCPC) standards L22A 2K0 and L22A 2K1 are
developed to cover the improvement of Flight Guidance and Envelope (FGE) behaviour
in some conditions of FCPC in alternate law.
(2) Objective/Action
It implies to replace the current FCPC standard L20 2K1 PN LA2K1A100290000
by new ones, FCPC standard L22A 2K1 PN LA2K1A1002B0000, electrically and
mechanically interchangeable and to replace the current FCPC standard L20 2K0 PN
LA2K01500290000 by new ones, FCPC standard L22A 2K0 PN LA2K015002B0000,
electrically and mechanically interchangeable.
Replace associated OBRM PN LA2K01500290400 by new one PN LA2K015002B0400.
Replace associated OBRM PN LA2K1A100290400 by new one PN LA2K1A1002B0400.
(3) Advantages
Main improvements introduced by L22A 2K0 and L22A 2K1 Standard :
- Reduction of High Vertical Speed (VZ) at touchdown with new parameters recording
in the DFDR (Digital Flight Data Recorder),
- Improvement of aircraft behaviour in case of erratic Air Data/Inertial Reference Unit
(ADIRU) outputs,
- Improvement of the reconfiguration logics in case of electrical transients during
rotation at Take Off (TFU 27.90.00.035),
- Improvement of the GS and PLD logics (ground spoiler and partial lift damping),
- Improvement of aircraft behaviour in case of two consistently erroneous AOA (Angle
Of Attack) information : limitation of Trimmable Horizontal Stabilizer (THS) at pitch
up,
- Maximum Operating Speed/Maximum Operating Mach (VMO/MMO) and autopilot
disconnection logic (A340-300 only),
- Autopilot inhibition engagement under unreliable airspeed condition.
(4) Operational/Maintenance Consequences
Accomplishment of this Service Bulletin will cancel the OEB 35 (formerly OEB 95 up
until 2011) and the Airplane Flight Manual (AFM) TR 150 according to Airworthiness
Directive No. 2010-0271.
Accomplishment of this Service Bulletin will also cancel the OEB 40 (formerly OEB 88
up until 2011).

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.
F. APPROVAL
The technical content of this document is approved under the authority of Design
Organization 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.
