Airworthiness Directives; Bell Textron Canada Limited Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for Bell Textron Canada Limited Model 505 helicopters. This AD was prompted by reports of cracked vertical stabilizer top end cap assemblies. This AD requires an initial and recurring inspections of the vertical stabilizer top end cap assembly and corrective action if a crack is found, as specified in a Transport Canada AD, which is incorporated by reference. The FAA previously sent this AD as an emergency AD to all known U.S. owners and operators of these helicopters. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 25 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies to helicopters as identified in Transport Canada Emergency AD CF-2024-03, dated January 25, 2024.

Whether AD 2024-02-55 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 2024-02-55 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.
