This AD applies to Piaggio Aero Industries S.p.A. Models P-180 airplanes, all serial numbers, certified in any category.
We are adopting a new airworthiness directive (AD) for the products listed above that will supersede an existing AD. This emergency AD was sent previously to all known U.S. owners and operators of PIAGGIO AERO INDUSTRIES S.p.A (Piaggio) Model PIAGGIO P-180 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
