Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Piaggio Aero Industries S.p.A. Model P-180 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 proposed AD to require actions to address the unsafe condition on these products.
