## Abstract

We are superseding Airworthiness Directive (AD) 2018-03-15 for Pacific Aerospace Limited Model 750XL 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 reports of finding abrasion damage behind the instrument panel caused by ventilation hose chafing. We are issuing this AD to require actions to address the unsafe condition on these products.
