What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD was prompted by a report of vibrations around the 12Hz frequency due to the specific helicopter configuration. This AD requires removing the removable parts of the dual hoist installation or removing the de-icing system. This AD also allows, for certain helicopters, revising the Rotorcraft Flight Manual (RFM) for your helicopter and installing a placard as an optional method of compliance. The FAA is issuing this AD to address the unsafe condition on these products.

Which aircraft AD 2020-09-15 applies to

MakesAirbus Helicopters

ModelsAS332C, AS332C1, AS332L, AS332L1, AS332

Applies only to helicopters equipped with a dual hoist installation and de-icing system, except those with Airbus Helicopters modification 0722907 installed in production.

Whether AD 2020-09-15 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 2020-09-15 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.
