Federal Aviation Administration June 1, 2023 – Federal Register Recent Federal Regulation Documents

This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA proposes to adopt a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-401 and -402 airplanes. This proposed AD was prompted by reports of the main landing gear (MLG) aft door not opening when using the alternate extension system. This proposed AD would require a one-time inspection of the spring box assembly, repetitive inspections of the cam assembly and alternate release cable assembly, corrective actions if necessary, and a replacement of certain alternate release cable assemblies. In addition, this proposed AD would also require certain aircraft maintenance manuals tasks when installing the cam assembly or alternate release cable assembly. This proposed AD would also prohibit the installation of affected parts. 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 Airbus SAS Model A350-941 and A350-1041 airplanes. This proposed AD was prompted by reports that excessively deep spot faces on the front engine mounting bolt holes on the wing pylon were detected on the production line. This proposed AD would require a one-time inspection for clash (interference) of the three front engine mounting bolt holes on both the left and right wing pylons, and, depending on findings, accomplishment of applicable corrective actions, 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 action amends Very High Frequency (VHF) Omnidirectional Range (VOR) Federal airway V-376 by removing the Nottingham, MD (OTT), VOR/Tactical Air Navigational System (VORTAC) from the route description and replacing it with the Casanova, VA (CSN), VORTAC. This action is required due to the planned decommissioning of the Nottingham, MD (OTT), VORTAC as part of FAA's VOR Minimum Operational Network (MON) program. This action does not change the alignment, altitudes, or operating requirements of V-376. In addition, language is added to exclude the airspace within restricted areas R-6601A, R-6601B, and R-6601C.
