Full official abstract
We are superseding Airworthiness Directive (AD) 2009-21-08 R1 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 cases of un-commanded operation of switched off nose-wheel steering system caused by internal leakage of a steering select/bypass valve. We are issuing this AD to require actions to address the unsafe condition on these products.
