What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Inc. (Bell) Model 204B, 205A, 205A-1, 205B, 212, 214B, 214B-1, 412, 412CF, and 412EP helicopters. This AD was prompted by a report of a shoulder harness seat belt comfort clip (comfort clip) interfering with the seat belt inertia reel. This AD requires removing comfort clips from service and inspecting the seat belt shoulder harness (harness) for a rip or an abrasion. The actions of this AD are intended to address an unsafe condition on these products.

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 2020-16490 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.
