Airworthiness Directives; Airbus SAS Airplanes

What this AD requires

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.

Which aircraft AD 2026-05-12 applies to

MakesAirbus Sas
ModelsA350-941, A350

Applies to airplanes as identified in European Union Aviation Safety Agency (EASA) AD 2026-0018, dated January 26, 2026.

Whether AD 2026-05-12 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2026-05-12 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
