Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Piaggio Aero Industries S.P.A. (Piaggio) Model P-180 airplanes. This proposed AD would require you to install a placard on the inside of the lavatory door that prohibits occupying the lavatory seat during takeoff and landing. This proposed AD also requires you to incorporate a temporary revision into the Limitations Section of the pilot operating handbook/airplane flight manual (POH/AFM). This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by this proposed 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.
