Department of Transportation January 27, 2023 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2022-04-09, which applies to certain AVOX System Inc. (formerly Scott Aviation) oxygen cylinder and valve assemblies; and oxygen valve assemblies; installed on but not limited to various transport airplanes. AD 2022-04-09 requires an inspection of the oxygen valve assemblies, and oxygen cylinder and valve assemblies, to determine the serial number; for certain assemblies and parts, a detailed inspection of the gap between the bottom of the packing retainer and top of the valve body on the assemblies; and replacement of assemblies having unacceptable gaps. Since the FAA issued AD 2022-04-09, the agency determined additional assemblies and parts are affected by the unsafe condition. This proposed AD would require an inspection of the oxygen valve assemblies, and oxygen cylinder and valve assemblies, to determine the serial number of the valve, cylinder, and entire assembly. For assemblies and parts with certain serial numbers, this proposed AD would require a detailed inspection for correct spacing of the gap between the bottom of the packing retainer and top of the valve body on the assemblies, and replacement of assemblies having unacceptable gaps. 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.

The FHWA, on behalf of the Arizona Department of Transportation (ADOT), is issuing this notice to announce actions taken by ADOT and other relevant Federal agencies that are final. The actions relate to the Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for the proposed project Sunset Road: I-10 to River Road, Pima County, Arizona. The actions grant licenses, permits, and approvals for the project.

The Federal Motor Carrier Safety Administration (FMCSA) requests public comment on Encore Building Products' (Encore) application for an exemption from the requirement that lighting devices be steady burning. The exemption would allow the company to operate commercial motor vehicles (CMVs), equipped with a module manufactured by Intellistop, Inc. (Intellistop) which pulses the rear clearance, identification, and brake lamps from low-level lighting intensity to high-level lighting intensity 4 times in 2 seconds when the brakes are applied. FMCSA requests public comment on the applicant's request for exemption.

This action amends the Class E airspace at Marshalltown, IA. This action is the result of an airspace review as part of the decommissioning of the Elmwood very high frequency (VHF) omnidirectional range (VOR) as part of the VOR Minimal Operational Network (MON) Program.

This action proposes to revoke Colored Federal airway Blue 38 (B-38) and Blue 40 (B-40) in the vicinity of Haines, AK due to the pending decommissioning of the Haines (HNS) Non-directional Beacon (NDB).

The FAA is adopting a new airworthiness directive (AD) for certain Mooney International Corporation Model M20C, M20D, M20E, M20F, and M20G airplanes. This AD was prompted by reports of the hybrid material elevator balance weight cracking. This AD requires inspecting to determine whether a certain elevator balance weight is installed. If installed, this AD requires inspecting each affected elevator balance weight for corrosion and cracking, and depending on the findings, either replacing each affected elevator balance weight with a non- hybrid (lead) elevator balance weight or repetitively inspecting each affected elevator balance weight. This AD also prohibits the installation of an affected elevator balance weight on any airplane. The FAA is issuing this AD to address the unsafe condition on these products.
