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
During inspection on an AIRBUS test aircraft, cracks have been detected on parts made of forging
aluminum 7037 due to an unexpected behavior of this material. AIRBUS decided to redesign the AFT
door latch fittings with material change to aluminum 7010T7652. This design change has been applied
in production from Manufacturer Serial Number (MSN) 0040.
For aircraft with MSN 0006 thru MSN 0039 the AFT cargo door latch fittings must be replaced due to
the material improvement from aluminum 7037 to aluminum 7010T7652.
This Service Bulletin details the installation of new AFT cargo-door latch fittings at FR79, FR79A, FR80
and FR80A in the lower part of the cargo door surround.
Accomplishment of this Service Bulletin cancels the requirements of Service Bulletin No. A350-53-P045.
The accomplishment of this Service Bulletin will ensure the 6 years threshold for the first General Visual
Inspection (GVI) in these affected areas.
