## Abstract

We are adopting a new airworthiness directive (AD) 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 non-compliant insulation lagging on the refrigerant hoses of the air-conditioning system. We are issuing this AD to require actions to address the unsafe condition on these products.
