Airworthiness Directives; Piaggio Aviation S.p.A. Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Piaggio Aviation S.p.A. (Piaggio) Model P-180 airplanes. This AD was prompted by a report of corrosion-induced cracking on the horizontal tail trim actuator (HTTA) fitting assembly. This AD requires repetitively inspecting the HTTA fitting assembly for corrosion and cracking until the HTTA fitting assembly is replaced with a new part. The FAA is issuing this AD to address the unsafe condition on these products.

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

Serial-conditional — narrows to serials 1002–1002, 1034–1234, 3001–3014, 3016–3016, 3018–3018, 1004–1033.

Serial numbers 1004 through 1033 inclusive apply only if modified in accordance with Piaggio Service Bulletin 80-0142.

Whether AD 2023-16-04 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 2023-16-04 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.
