Airworthiness Directives; Bell Helicopter Textron Model 206A and 206B Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron (Bell) Model 206A and 206B helicopters modified by Aeronautical Accessories, Inc. Supplemental Type Certificate (STC) SH1392SO with certain part-numbered high crosstubes. This amendment requires inspecting at specified time intervals and replacing any cracked crosstubes. This amendment is prompted by the discovery of a cracked high forward crosstube. The actions specified by this AD are intended to detect a crack in the crosstube which could lead to failure of the crosstube, collapse of the landing gear, and subsequent loss of control of the helicopter.

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 2005-16-04 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.
