Is AD 2014-28913 a recurring Airworthiness Directive?

No — AD 2014-28913 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2014-28913 apply to?

AD 2014-28913 applies to Agusta — models AB139, AW139. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Agusta S.p.A. (Agusta) Helicopters

What this AD requires

We are revising Airworthiness Directive (AD) 2008-14-02 for Agusta Model AB139 and AW139 helicopters. AD 2008-14-02 required inspecting the fuselage frame to detect fatigue cracks which could lead to structural failure and subsequent loss of control of the helicopter. Since we issued AD 2008-14-02, Agusta developed a frame reinforcement modification, which supports extending the interval for inspecting the fuselage frame for a fatigue crack. This new AD requires inspecting the fuselage frame for a crack and reduces the applicability from AD 2008- 14-02 to exclude helicopters with the frame reinforcement modification. The actions of this AD are intended to detect a fatigue crack that could result in failure of the fuselage frame and subsequent loss of control of the helicopter.

Whether AD 2014-28913 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.

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.
