What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2022-19- 09, which applied to all Airbus Canada Limited Partnership Model BD- 500-1A10 and BD-500-1A11 airplanes. AD 2022-19-09 required repetitive inspections of the left and right main landing gear (MLG) lower spindle pins to detect corrosion and applicable repair or replacement. This AD was prompted by reports of in-service findings of corrosion on the flange of the MLG lower spindle pin. This AD continues to require certain actions in AD 2022-19-09. This AD also requires changing the tracking of flight cycles for inspections from the usage of the MLG to the usage of MLG lower spindle assemblies and replacement of affected MLG lower spindle assemblies, removes airplanes from the applicability, and prohibits the installation of affected parts under certain conditions; as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies to airplanes as identified in Transport Canada AD CF-2023-66, dated October 3, 2023. Type certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.

Whether AD 2025-08338 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 2025-08338 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.
