Is AD 2015-09548 a recurring Airworthiness Directive?

Yes — AD 2015-09548 requires a repetitive inspection every 85 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2015-09548 apply to?

AD 2015-09548 applies to Airbus Helicopters — models EC225LP, EC225. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Airbus Helicopters (Type Certificate Previously Held by Eurocopter France)

What this AD requires

We are adopting a new airworthiness directive (AD) for Airbus Model EC225LP helicopters. This AD requires repetitive visual and tap test inspections of each main rotor blade (blade) leading edge stainless steel protective strip (strip) for a crack, cut, or blind or open debonding (debonding), and taking approved corrective measures. If there is a crack or if there is debonding that exceeds acceptable limits, this AD requires, before further flight, repairing or replacing the blade with an airworthy part. This AD was prompted by suspected water seepage through a crack in the blade strip resulting in significant debonding. The actions of this AD are intended to prevent loss of the blade strip, excessive vibrations induced by blade weight imbalance, and subsequent loss of control of the helicopter.

Repetitive inspection. Re-inspect every 85 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies only to helicopters with the specified main rotor blade part number installed.

Whether AD 2015-09548 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 2015-09548 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.
