Federal Aviation Administration November 28, 2022 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes. This proposed AD was prompted by a determination that a new airworthiness limitation is necessary to require periodic replacement of the oxygen sensor of the nitrogen generation system (NGS). This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate the new airworthiness limitation. The FAA is proposing this AD to address the unsafe condition on these products.

This action corrects a final rule published by the FAA in the Federal Register on October 24, 2022, that amends United States Area Navigation (RNAV) route T-269 in the vicinity of Yakutat, AK, in support of a large and comprehensive T-route modernization project for the state of Alaska. The final rule identified the MALAS, AK, route point as a waypoint (WP), in error. This action makes an editorial correction to the reference of the MALAS, AK, WP to change it to be reflected as a Fix and match the FAA's National Airspace System Resource (NASR) database information.

This action amends the Class E airspace at Liberal, KS. This action is the result of an airspace review conducted as part of the decommissioning of the Liberal very high frequency (VHF) omnidirectional range (VOR) as part of the VOR Minimal Operational Network (MON) Program. The name and geographic coordinates of the airport and the name of the navigational aid are also being updated to coincide with the FAA's aeronautical database.

This action amends the Class E airspace at Independence and Pittsburg, KS. This action is the result of an airspace review conducted as part of the decommissioning of the Oswego very high frequency (VHF) omnidirectional range (VOR) as part of the VOR Minimal Operational Network (MON) Program. The geographic coordinates of the airports are also being updated to coincide with the FAA's aeronautical database.

The FAA proposes to adopt a new airworthiness directive (AD) for all Bell Textron Canada Limited Model 206A, 206A-1 (OH-58A), 206B, 206B-1, 206L, 206L-1, 206L-3, and 206L-4 helicopters. This proposed AD was prompted by a loss of tail rotor (TR) drive due to a failure of an adhesively bonded joint between an adapter and a tube on one of the segmented TR drive shaft (TRDS) assemblies. This proposed AD would require determining if an affected TRDS is installed; repetitively inspecting the bond line for damage; repetitively performing a proof load test of the TRDS assembly; and depending on the results of the inspections or the proof load tests, removing an affected TRDS from service and replacing it with a serviceable TRDS. This proposed AD would also prohibit installing a TRDS unless it meets certain requirements, as specified in a Transport Canada AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
