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 replace the four defective horizontal stabilizer hinge bushings with replacement bushings. 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 replace defective bushings, which could result in reduced or loss of control of the aircraft.
