What this AD requires

We are adopting a new airworthiness directive (AD) for certain Bell Helicopter Textron, Inc. (Bell), Model 204B, 205A, 205A-1, and 212 helicopters. This AD requires removing a certain part-numbered main rotor (M/R) blade grip (grip) from service. This AD is prompted by an error in a parts manufacturer approval (PMA) that incorrectly allows installation of the grips on the Bell Model 212. The actions specified in this AD are intended to prevent grip failure, separation of the M/R blade, and subsequent loss of control of the helicopter.

(1) Applies to Model 204B, 205A, and 205A-1 helicopters with main rotor blade grip P/N ASI-4011-121-113 installed, if the grip was ever installed on a Model 212 helicopter or it is unknown whether it was; (2) applies to Model 212 helicopters with grip P/N ASI-4011-121-113 installed.

Whether AD 2015-15-04 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 2015-15-04 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.
