Airworthiness Directives; Various Restricted Category Helicopters

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2021-15-52 which applied to various restricted category helicopters originally manufactured by Bell Textron Inc. with a certain main rotor hub strap pin (pin) installed. AD 2021-15-52 required removing certain outboard pins from service and prohibited installing them on any helicopter. This AD expands the applicability to all affected pins, regardless if they are outboard or inboard. This AD also requires inspecting the removed pin for any deformation and if it is deformed, removing the mating strap fitting (fitting) from service. This AD was prompted by the discovery that AD 2021-15-52 inadvertently limited its applicability to only outboard pins when, in fact, all pins are subject to the unsafe condition and the determination that a deformed pin may have damaged the fitting. Finally, this AD updates the current type certificate holder information as reflected in the type certificate data sheet (TCDS) and expands the applicability of AD 2021-15-52. The FAA is issuing this AD to address the unsafe condition on these products.

Supersedes AD 2021-15-52.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2022-05379 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.
