Airworthiness Directives; Piaggio Aero Industries S.p.A. Model P-180 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Piaggio Aero Industries S.p.A. (Piaggio) Model P-180 airplanes. This AD requires you to install a placard on the inside of the lavatory door that prohibits occupying the lavatory seat during takeoff and landing. This AD also requires you to incorporate a temporary revision into the Limitations Section of the pilot operating handbook/airplane flight manual (POH/AFM). This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by this AD are intended to prevent passengers from occupying the lavatory seat during takeoff and landing. The lavatory/cabin partition could fail and lead to passenger injury in an emergency situation.
