## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. This proposed AD was prompted by a report of an improper heat treatment process applied during the manufacturing of certain titanium screws. This proposed AD would require replacement of certain titanium screws, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
