REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

New software standard L19/M18 on Flight Control Secondary Compute

in order to take into account the last FCSC software evolutions.

This Service Bulletin is published to inform all operators of A34

the issue of AIRBUS FRANCE SAS Service Bulletin No. LA2B0-27-005.

This Service Bulletin recommends introducing new software "L19/M1

replacement or reprogramming or FCSCs replacement.

Accomplishment of this Service Bulletin introduces the improvemen

:

— modification of others computers monitoring

— new elevator position monitoring function, which cancels the OE

— correction of spurious alarm of Pedal Feel and Trim Unit (PFTU)

— modification of parameters record when computer fault.

NOTE : To take into account the "new elevator position monitoring

aircraft level, this new FCSC needs to be associated with 

Primary Computer (FCPC) standard which are being developed

will mandate the modification of both FCSC and FCPC to perm

cancellation of red OEB 54-3

NOTE : FCSC STD L19/M18 can be installed on basic aircraft.
