Airworthiness Directives; Agusta S.p.A. Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AW189 helicopters. This AD requires inspecting and altering the emergency flotation system (EFS). This AD is prompted by a report of punctured EFS kits. The actions of this AD are intended to prevent an unsafe condition on these helicopters.

MakesAgusta S.P.A.
ModelsAW189
Serial-conditional — narrows to serials ?–066, ?–068, ?–068, ?–067.
Part-conditional — 8G9560V00131, 8G9560V00231, 8G9560V00331, 8G9560V00431.

Applies only to helicopters with an EFS float assembly P/N 8G9560V00131 (S/N 066 or lower), P/N 8G9560V00231 (S/N 068 or lower), P/N 8G9560V00331 (S/N 068 or lower), or P/N 8G9560V00431 (S/N 067 or lower) installed.

Whether AD 2018-03-18 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 2018-03-18 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.
