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

What this AD requires

This amendment supersedes an existing airworthiness directive (AD) for the specified Agusta S.p.A. (Agusta) model helicopters. This AD results from a revised mandatory continuing airworthiness information (MCAI) issued 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, reports that the previous MCAI should not apply to newly redesigned and improved tail rotor blades. This AD requires the same inspections as the current AD but limits the applicability to only three part-numbered tail rotor blades. This AD requires actions that are intended to prevent fatigue failure of a tail rotor blade (blade), loss of a tail rotor, and subsequent loss of control of the helicopter.

Which aircraft AD E8-27611 applies to

MakesAgusta
ModelsA109A, A109A II, A109
Part-conditional — 109-0132-02-11, 109-0132-02-15, 109-0132-02-121.

Applies only to helicopters with a tail rotor blade P/N 109-0132-02-11, -15, or -121 installed, with 400 or more hours time-in-service; narrows prior AD 99-27-12, which covered all 109-0132-02 dash numbers, and does not apply to blade P/N 109-0132-02-125.

Whether AD E8-27611 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

Supersession

Supersedes AD 99-27-12.

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 E8-27611 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.
