What this AD requires

This amendment adopts a new airworthiness directive (AD) for the specified Bell Helicopter Textron, Inc. (Bell) helicopters. This action requires visually inspecting each main rotor blade box beam clip (clip) for correct installation. This amendment is prompted by a report of a main rotor blade with an incorrectly installed clip. The actions specified in this AD are intended to prevent a main rotor blade spar crack as a result of an incorrectly installed clip, loss of a main rotor blade, and subsequent loss of control of the helicopter.

Applies only when main rotor blade P/N 047-110-250-021 (blade S/N A-303, A-304, A-312, or A-316) or P/N 047-110-250-023 (blade S/N A-298, A-301, or A-305) is installed.

Whether AD 2009-12-01 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 2009-12-01 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.
