Airworthiness Directives; Airbus Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model EC225LP helicopters. This AD requires various inspections of the left-hand side (LH) engine fuel supply (fuel supply) hose and depending on the inspection results, reinstalling the fuel supply hose or removing the fuel supply hose from service. Additionally, this AD requires installing an improved part and prohibits installing a certain part-numbered LH fuel supply hose on any helicopter unless it is installed by following certain procedures. This AD was prompted by a report of an incorrect installation of the LH fuel supply hose causing restricted fuel flow to the LH engine. The FAA is issuing this AD to address the unsafe condition on these products.

Part-conditional — 704A34416087.

Applies only if a left-hand side (LH) engine fuel supply hose, P/N 704A34416087, is installed.

Whether AD 2021-05-03 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 2021-05-03 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.
