Airworthiness Directives; Bell Textron Canada Limited Helicopters

What this AD requires

The FAA is superseding Emergency Airworthiness Directive (AD) 2021-05-52 which applied to certain Bell Textron Canada Limited (Bell) Model 505 helicopters. Emergency AD 2021-05-52 required a one-time visual inspection of the pilot collective stick and grip assembly (pilot collective stick), a fluorescent penetrant inspection (FPI) if no crack was found during the visual inspection, and depending on the inspection results, removing the pilot collective stick from service and reporting certain information to Bell. Emergency AD 2021-05-52 also prohibited installing any pilot collective stick on any helicopter unless the inspections had been accomplished. This AD removes the visual inspection of the pilot collective stick, requires repetitive FPIs of the pilot collective stick, and requires revising the existing Rotorcraft Flight Manual (RFM) for your helicopter. This AD retains the reporting requirement and expands the prohibition. This AD was prompted by the determination that visual inspections do not adequately detect a crack and additional findings that a crack may occur sooner than previously expected. 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.

Serial-conditional — narrows to serials 65011–?.

Applies to serial numbers 65011 and subsequent, certificated in any category.

Whether AD 2021-06-06 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 2021-06-06 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.
