What this AD requires

The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. As published, two references to a Transport Canada Civil Aviation (TCCA) AD number specified in the regulatory text are incorrect. This document corrects those errors. In all other respects, the original document remains the same.

Type certificate previously held by C Series Aircraft Limited Partnership (CSALP)/Bombardier, Inc. Applies to airplanes as identified in Transport Canada Civil Aviation (TCCA) AD CF-2021-10, dated March 18, 2021.

Whether AD 2021-08760 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 2021-08760 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.
