Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Model PIAGGIO P-180 Airplanes

What this AD requires

We are clarifying information contained in Airworthiness Directive (AD) 2009-21-08, which applies to PIAGGIO AERO INDUSTRIES S.p.A. (Piaggio) Model PIAGGIO P-180 airplanes. AD 2009-21-08 currently requires repetitive functional tests of the manifold system and replacement of any system that does not pass the functional tests (i.e., movement of the steering system). The language in AD 2009-21-08 incorrectly references not passing the functional tests as "movement of the manifold," and it should read "movement of the steering system" as specified in the service bulletin. The notice of proposed rulemaking (NPRM) referenced it as specified in the service bulletin. This document incorporates the intent of the action as already proposed in the NPRM. We are issuing this AD to prevent a potentially dangerous veer along the runway. The steering system must be in the `off' position during landing and takeoff (in this case when airspeed is higher than 60 knots) according to the aircraft flight manual limitations.

Repetitive inspection. Re-inspect every 165 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 2009-21-08 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 2009-21-08 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.
