Summary
We propose to adopt a new airworthiness directive (AD) for Pacific Aerospace Limited (PAL) Model 750XL airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 PAL Model 750XL airplanes manufactured with only one attitude indicator. A second attitude indicator is required for flights under instrument flight rules. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
