Is AD 2021-02-03 a recurring Airworthiness Directive?

Yes — AD 2021-02-03 requires a repetitive inspection every 500 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2021-02-03 apply to?

AD 2021-02-03 applies to Leonardo S.P.A. — models AW189. Serial/part conditions may narrow it to specific aircraft.

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. (Leonardo) Model AW189 helicopters. This AD requires various repetitive inspections of the main rotor (MR) damper. This AD was prompted by reports of in-service MR damper failures and the development of an improved MR damper. This condition, if not corrected, could lead to loss of the lead-lag damping function of the MR blade, possibly resulting in damage to adjacent critical rotor components and subsequent loss control of the helicopter. The actions of this AD are intended to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 500 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

ModelsAW189

Part-conditional — 4F6220V00251.

Applies only when a main rotor (MR) damper P/N 4F6220V00251 is installed.

Whether AD 2021-02-03 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 2021-02-03 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.
