Summary
We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by a fuel leak that occurred in the baggage compartment during fuel system pressurization. This proposed AD would require opening the fuel boxes and restoring the sealing. We are proposing this AD to detect and correct failure of a connector or coupling on a fuel line, which, in combination with a leak in the corresponding enclosure (i.e., fuel box), could result in a fire in the baggage compartment and affect the safe flight of the airplane.
