Airworthiness Directives; Agusta Model A109A, A109AII, and A109C Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) applicable to Agusta Model A109A, A109AII, and A109C helicopters. This action requires inspecting the main transmission to determine if certain Gleason crowns are installed and replacing any unairworthy Gleason crown with an airworthy Gleason crown. This amendment is prompted by the discovery of a cracked Gleason crown during an unscheduled transmission inspection prompted by abnormal noises coming from the transmission during main rotor deceleration. The actions specified in this AD are intended to prevent failure of the main transmission, loss of rotor drive, and subsequent loss of control of the helicopter.

Which aircraft AD 2000-08-02 applies to

MakesAgusta
ModelsA109
Part-conditional — 109-0400-02-5, 109-0400-03-105, 109-0403-07, 109-0403-07-103.

Applies when a main transmission P/N 109-0400-02-5 or 109-0400-03-105 with one of 11 discrete transmission/Gleason-crown S/N pairs in Table 1 is installed; if the matching Gleason crown P/N 109-0403-07 is installed, replace with airworthy P/N 109-0403-07-103, S/N B58264 or subsequent (except S/N B58271). Per Agusta Bollettino Tecnico 109-109, dated Jun 3, 1999.

Whether AD 2000-08-02 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 2000-08-02 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.
