Airworthiness Directives; Agusta S.p.A. Model A109E Helicopters

What this AD requires

This amendment supersedes an existing airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109E helicopters that currently requires visually checking and inspecting each tail rotor blade (blade) for a crack at specified intervals. That AD also requires replacing any cracked blade with an airworthy blade. This amendment contains the same requirements but adds another blade to the applicability. This amendment is necessary because the added blade is manufactured using the same process as the blade that failed. The actions specified by this AD are intended to prevent failure of a blade and subsequent loss of control of the helicopter.

Cross-reference boilerplate only; model list precedes excerpt and was not captured. Requires repetitive visual/dye-penetrant crack inspection of tail rotor blades P/N 109-8132-01-107 and 109-8132-01-109 per Agusta Bollettino Tecnico 109EP-14, Revision A, dated March 19, 2001.

Whether AD 2001-17-16 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 2001-17-16 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.
