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

What this AD requires

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2000-17-52, which was sent previously to all known U.S. owners and operators of Agusta S.p.A. (Agusta) Model A109E helicopters by individual letters. This AD requires, before further flight, visually inspecting any main rotor rotating scissors assembly for correct installation and replacing any unairworthy part with an airworthy part. If the rotating scissors attachment bolt (attachment bolt) is not replaced with a new part at the initial inspection, this AD also requires removing the rotating scissors assembly to inspect the attachment bolt for a crack and replacing any cracked attachment bolt with a new attachment bolt before further flight. This amendment is prompted by two incidents of flight control malfunctions. The actions specified by this AD are intended to prevent failure of the rotating scissors assembly and subsequent loss of control of the helicopter.

Whether AD 2000-17-52 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.

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.
