## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:

Due to pressurization loads, the fuselage frame of the emergency exit door could suffer from fatigue and develop cracks in its corners. The superseded Italian Airworthiness Directive (AD) 1995- 059 was issued to require modification of the emergency door frame in accordance with Piaggio (at the time I.A.M. Rinaldo Piaggio S.p.A.) Service Bulletin 80-0057 original issue.

Parts necessary to carry out the modification were a new door pan assembly and a doubler; Since these parts are no longer available, Piaggio Aero Industries S.p.A. (PAI) designed new suitable part numbers introduced by Revision 1 of Service Bulletin 80-0057. The presentAD mandates modification of the fuselage emergency door frame in accordance with Revision 1 of Service Bulletin 80-0057 from PAI.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
