Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A. Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for PIAGGIO AERO INDUSTRIES S.p.A. Model P-180 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as disbonding of the upper and lower metal skin from the honeycomb core on the elevator assembly and other flight control surfaces. We are issuing this AD to require actions to address the unsafe condition on these products.

ModelsP-180
Serial-conditional — narrows to serials 1002–1002, 1004–1220.

Applies only to airplanes equipped with flight control surfaces (part numbers and serial numbers) not listed in Table 1 of Piaggio Aero Industries S.p.A. Mandatory Service Bulletin No. 80-0455, dated January 13, 2017.

Whether AD 2017-20-13 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 2017-20-13 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.
