Airworthiness Directives; Bell Textron Inc. (Type Certificate Previously Held by Bell Helicopter Textron Inc.) Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for Bell Textron Inc. (Bell) Model 214ST helicopters. This AD was prompted by the discovery of bolts with nonconforming external thread root radii. This AD requires removing the affected bolts from service and prohibits installing an affected bolt on any helicopter. The FAA is issuing this AD to address the 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 2020-14210 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.
