Federal Register #2026-23074

Proposed FAA airworthiness directive for Dassault Aviation aircraft landing gear

The FAA proposes an airworthiness directive for certain Dassault Aviation aircraft to address a landing-gear safety concern. - Government authority: U.S. Department of Transportation, Federal Aviation Administration (FAA). - Aircraft manufacturer (OEM): Dassault Aviation; affected models are MYSTERE-FALCON 50, FALCON 2000, and FALCON 2000EX. - Safety issue: Possible high-temperature oxidation of main landing gear (MLG) upper and lower torque links following a reported manufacturing quality escape. - Proposed actions: Replace affected MLG with serviceable MLG and restrict installation of affected parts under specified conditions. The proposal incorporates a directive from the European Union Aviation Safety Agency (EASA). - Scope: The FAA estimates 683 U.S.-registered aircraft could be affected, with up to 178 potentially requiring MLG replacement. - This is a proposed safety rule, not a procurement opportunity; no products or services are being solicited for purchase.
