Airworthiness Directives; Agusta S.p.A. (Type Certificate Currently Held by AgustaWestland S.p.A.) (Agusta) Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Agusta AB139 and AW139 helicopters to require replacing certain single-braided flexible hydraulic hoses with double-braided flexible hydraulic hoses. This AD was prompted by occurrences of leaking flexible hydraulic hoses. The actions of this AD are intended to prevent loss of hydraulic power and subsequent loss of helicopter control.

Applies only to helicopters with one of the specified flexible hydraulic hose part numbers installed.

Whether AD 2015-01809 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 2015-01809 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.
