## Summary

We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by investigation results that determined that a certain thickness of the fuel tank panels is insufficient to meet the certification requirements. This proposed AD would require inspecting the thickness of the fuel tank panels, and repair if necessary. We are proposing this AD to detect and correct improper thickness of the fuel tank panels. Improper thickness increases the risk of damaging and puncturing a fuel tank wall panel as a result of a high energy lightning strike, which could lead to loss of electrical power and/or other essential functions, possibly resulting in reduced control of the airplane or ignition of a fuel tank.
