## Abstract

We are adopting a new airworthiness directive (AD) for Pilatus Aircraft Limited Model PC-7 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 the brakes remaining activated after release of the brake pedal. We are issuing this AD to require actions to address the unsafe condition on these products.
