Summary
We propose to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as insufficient clearance between the pitot tubes and the primary support at the flame arrester intersection. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
