## Summary

We propose to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL (type certificate previously held by Pacific Aerospace Corporation Ltd.) airplanes that would supersede AD 2006-13-05. 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 some critical rivets on the wing not being fully age- hardened and being installed in specific locations where reduction in rivet strength reduces wing strength. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
