Airworthiness Directives; Piaggio Aero Industries S.P.A Airplanes

We are adopting a new airworthiness directive (AD) for certain Piaggio Aero Industries S.P.A Model P-180 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 insufficient clearance between one of the horizontal stabilizer end ribs and the corresponding elevator horn. We are issuing this AD to require actions to address the unsafe condition on these products.
