Notice of proposed rulemaking (NPRM).
Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Dassault Aviation Model Falcon 10 airplanes. This proposed AD was prompted by a report of hydraulic fluid on the ground near the main landing gear (MLG) brake assembly. The hydraulic leakage started in a cracked hydraulic pipe, with the crack likely due to chafing between two hydraulic pipes or between hydraulic pipes and structure. This proposed AD would require an inspection for chafing or interference of certain hydraulic pipes and certain rib passage holes, and, depending on findings, modification or repair, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
