What the agency says
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a report of a non-conformity in the serialization process of certain fuse pins and retaining pins installed in the main landing gear (MLG) trunnion block attachment, resulting in a non-unique combination of part number and serial number that could lead to a lack of traceability. This AD requires doing a check to identify the part number and serial number of the affected parts. This AD also requires inspecting the affected MLG trunnion block attachment retaining pin and fuse pins, recording the combination of work order number and original serial number as the new serial number, and updating the maintenance records, as applicable. The FAA is issuing this AD to address the unsafe condition on these products.
