Airworthiness Directives; AGUSTA S.p.A. Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AW139 helicopters to determine if the hardware that attaches the upper end of collective control rod C2 to torque tube C3 is properly installed. This AD is prompted by the discovery of an incorrectly-attached collective control rod. These actions are intended to prevent separation of the collective control rod from the torque tube, loss of control of the collective pitch, and subsequent loss of control of the helicopter.

Whether AD 2012-11-12 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 2012-11-12 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.
