Airworthiness Directives; Agusta S.p.A. Model AB412 and AB412 EP Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for the specified Agusta S.p.A. (Agusta) Model AB412 and AB412 EP helicopters. This AD results from mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI establishes a life limit for certain rescue hoist cable assemblies and introduces the term "hoist lift" for determining cable life instead of the term "hoist cycle." The MCAI also establishes a replacement time for each affected rescue hoist cable assembly (hoist cable assembly) for which the accumulated number of "hoist cycles" cannot be determined. The actions are intended to prevent failure of a hoist cable and inadvertent loss of a load.

Which aircraft AD 2009-18-17 applies to

MakesAgusta
ModelsAB412, AB412 EP
Part-conditional — 214-070-300-1, 42277-1, BL-10300-60, BL-20200-SERIES.

Applies only to helicopters with internal hoist P/N 214-070-300-1 (Goodrich P/N 42277-1), or external hoist P/N BL-10300-60 or BL-20200-SERIES (Breeze Eastern), installed.

Whether AD 2009-18-17 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 2009-18-17 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.
