Airworthiness Directives; Airbus Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS 332L2 and EC 225LP helicopters. This AD was prompted by reports of overlengthened and deformed attachment bolts installed on the link of the main gearbox (MGB) suspension bar attachment bracket. This AD requires replacing certain attachment bolts on the MGB suspension bar fittings, inspecting the removed bolts, and reporting the results of this inspection to Airbus Helicopters. The FAA is issuing this AD to address the unsafe condition on these products.

ModelsAS332L2, EC225LP, AS332, EC225

Applies to helicopters identified in European Union Aviation Safety Agency AD 2024-0142, dated July 17, 2024 (EASA AD 2024-0142).

Whether AD 2025-18-09 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2025-18-09 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.
