Airworthiness Directives; Agusta S.p.A. Model A119 Helicopters

What this AD requires

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2001-22-51, which was sent previously to all known U.S. owners and operators of Agusta S.p.A. (Agusta) Model A119 helicopters by individual letters. This AD requires removing a certain part-numbered tail rotor blade (blade) on or before accumulating 50 hours time-in-service (TIS). This AD also requires visually or dye penetrant inspecting each blade at specified time intervals and removing any cracked blade before further flight. This AD is prompted by the discovery of a fatigue crack on a blade during an inspection. The actions specified by this AD are intended to prevent failure of a blade and subsequent loss of control of the helicopter.

Part-conditional — 109-8132-01-107.

Applies only when tail rotor blade P/N 109-8132-01-107 is installed.

Whether AD 2001-22-51 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 2001-22-51 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.
