## Summary

The FAA proposes 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 correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as insufficient separation of ground terminations for individual power sources and static grounds. This proposed AD would require inspecting and separating, if applicable, the battery

and generator common ground connections on the airframe. The FAA is proposing this AD to address the unsafe condition on these products.
