REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES
Investigations have shown that an identified batch of cargo doors might have deviations in quality, such
as irregular bore holes, improper application of sealant and paint or cleanliness. These deviations are
related to the quality of the door structure. AIRBUS have decided to inspect the in-service aircraft with
potentially affected forward (FWD) cargo door delivered since end of 2006.
This Service Bulletin details the procedure to inspect the cargo door for non-conformity of the door
structure with the specification requirements. Non-conformity leads to the replacement of the cargo
door.
The accomplishment of this Service Bulletin ensures the conformity of the cargo door structure with the
specification requirements.
