NPRM FAA-2026-13805

The FAA proposes to adopt a new airworthiness directive (AD) for all Dassault Aviation Model MYSTERE-FALCON 50, FALCON 2000, and FALCON 2000EX airplanes. This proposed AD was prompted by a reported quality escape and a determination that high-temperature oxidation of main landing gear (MLG) upper and lower torque links may have occurred during manufacturing. This proposed AD would require replacing any affected MLG with a serviceable MLG. This proposed AD would also limit the installation of affected parts under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
