Airworthiness Directives; Agusta S.p.A. Model AB139 and AW139 Helicopters

What this AD requires

We are superseding an existing airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB139 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The aviation authority of Italy, with which we have a bilateral agreement, states in the MCAI:

MakesAgusta

ModelsAB139, AW139

Part-conditional — 3G7800L00131, 3G7800L00231.

Applies to all serial numbers except 31002, 31003, 31004, and 31007, when tailpipe assembly P/N 3G7800L00131 (LH) or 3G7800L00231 (RH) is installed, certificated in any category.

Whether AD 2007-25-14 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 2007-25-14 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.
