Notice of proposed rulemaking (NPRM).

We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This proposed AD was prompted by reports of a loose screw on certain slat mechanical stop assemblies, and punctures in certain fuel caps. This proposed AD would require a one-time inspection, and corrective action if necessary. We are proposing this AD to address the unsafe condition on these products.
