Federal Aviation Administration April 14, 2023 – Federal Register Recent Federal Regulation Documents

This action proposes to establish Class E airspace at Berclair, TX. The FAA is proposing this action as the result of a request from the U.S. Navy to establish Class E airspace at Goliad NOLF, Berclair, TX, to support instrument procedures at this airport.

This action proposes to amend the Class E airspace at Madison Dane County Regional Airport-Truax Field, WI, and establish Class E airspace at Madison, WI. The FAA is proposing this action as the result of an airspace review requested by the FAA Airspace Rules and Regulations office. The name and geographic coordinates of various airports would also be updated to coincide with the FAA's aeronautical database.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD 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.

The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model 4101 airplanes. This proposed AD was prompted by in-service cracking of the passenger door edge member, seal carrier, and inner skin, adjacent to the roller guide bracket. This proposed AD would require a one-time inspection of the external visible surface of the inner skin, door edge member, and seal carrier adjacent to the roller bracket attachment brackets; and the inner skin, door edge member, and seal carrier at the roller bracket attachment bore, and repair if necessary. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This proposed AD was prompted by a report that an incorrect wiring arrangement was detected around the weather radar system. This proposed AD would require modifying the weather radar redundant wiring, 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 is superseding Airworthiness Directive (AD) 2022-27- 07, which applied to certain The Boeing Company Model 747-400 and 747-8 series airplanes. AD 2022-27-07 required inspecting for wear of the transfer pump housing inlet check valves and transfer pump motor impeller inlet adapters for the horizontal stabilizer fuel tank and doing corrective actions, if necessary. This AD was prompted by the discovery that certain airplanes were incorrectly included in the applicability of AD 2022-27-07. This AD continues to require inspecting for wear of the transfer pump housing inlet check valves and transfer pump motor impeller inlet adapters for the horizontal stabilizer fuel tank and doing corrective actions, if necessary. This AD also removes certain airplanes from the applicability, redefines the definition of an ``activated'' horizontal stabilizer fuel tank, and limits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
