Summary
We propose to rescind an airworthiness directive (AD) for PIAGGIO AERO INDUSTRIES S.p.A. Model P-180 airplanes. The existing AD resulted 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 partial detachment of the inner protective film of the composite nacelles. Since issuance of that AD, we have determined that the unsafe condition does not exist or is not likely to develop on affected type design airplanes, and therefore the AD should be rescinded. The proposed AD would allow the public the opportunity to comment on the FAA's determination of the unsafe condition no longer existing before it is officially rescinded.
