Abstract
We are adopting a new airworthiness directive (AD) for Piaggio Aero Industries S.p.A. Model P-180 Airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 jamming of the external bearing of the screwjack drive gear, which resulted in failure of the main wing outboard flap external actuator. We are issuing this AD to require actions to address the unsafe condition on these products.
