## Abstract

The FAA is 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 insufficient sealing of a steering select/bypass valve installed in the nose landing gear (NLG) manifold. The FAA is issuing this AD to address the unsafe condition on these products.
