Federal Aviation Administration April 23, 2024 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2022-13-11, which applies to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2022-13-11 requires revising the existing airplane flight manual (AFM) for airplanes equipped with affected flight control units (FCUs) and replacing any affected FCU with a serviceable FCU. Since the FAA issued AD 2022-13-11, the FAA has determined that it is necessary to expand the applicability of the AFM revision requirement to all Model A350-941 and -1041 airplanes, including those equipped with serviceable FCUs. This proposed AD would continue to require certain actions in AD 2022-13-11, including replacing any affected FCU with a serviceable FCU, expand the requirement to revise the existing AFM for all airplanes, and prohibit the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2023-02-13, which applies to certain Dassault Aviation Model FALCON 900EX airplanes. AD 2023-02-13 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-02-13, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2023-02-13 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

This notice summarizes the petition Boom Supersonic, Inc. submitted to the FAA requesting a special flight authorization as provided for in FAA regulations. The notice also provides for public awareness of FAA's decision to grant Boom Supersonic, Inc.'s request. The FAA is not requesting comments on the petition or the FAA's decision regarding the petition because a special flight authorization petition to exceed Mach 1 follows a separate regulatory process.
