Airworthiness Directives; Leonardo S.p.a. Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109, A109A, A109A II, A109C, A109E, A109K2, A109S, and AW109SP helicopters modified by Supplemental Type Certificate (STC) SR01812LA. This AD was prompted by a report of certain floats not deploying due to a faulty plunger assembly. This AD requires repairing or replacing certain float assemblies. The FAA is issuing this AD to address the unsafe condition on these products.

Applies only to helicopters modified by Supplemental Type Certificate SR01812LA with A109 Float (with/without Liferafts System) DART Aerospace 634.4100 Kit Series installed with one of the specified float assembly part numbers.

Whether AD 2023-01-02 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 2023-01-02 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.
