Airworthiness Directives; Agusta S.p.A. Model A109A, A109A II, and A109C Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for the specified Agusta S.p.A. (Agusta) model 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 European Aviation Safety Agency (EASA), the Technical Agent for Italy, with which we have a bilateral agreement, states in the MCAI:

Which aircraft AD 2008-09-03 applies to

MakesAgusta

ModelsA109A, A109AII, A109C, A109

Part-conditional — 4606AC.

Applies only to helicopters with grooved clamps, P/N 4606AC, that attach the engine exhaust ducts, installed. Fracture of the clamp (from excessive loads and corrosion around the attaching rivets) can release the duct, which may strike the main and tail rotor.

Whether AD 2008-09-03 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 2008-09-03 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.
