Airworthiness Directives; Leonardo S.p.A. Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.A. Model A119 and AW119 MKII helicopters. This AD was prompted by a report of an electrical failure of the starter-generator, due to a rupture of the drive shaft, which resulted in a partial loss of battery power. This AD requires installing a battery discharge detector and revising the existing Rotorcraft Flight Manual (RFM) for the helicopter. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2025-09-06 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 2025-09-06 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.
