Federal Aviation Administration November 4, 2022 – Federal Register Recent Federal Regulation Documents

The FAA is withdrawing the NPRM published in the Federal Register on October 25, 2021, proposing to establish RNAV route T-384 in the vicinity of Eagle, AK, in support of a large and comprehensive T-route modernization project for the state of Alaska. Subsequent to the NPRM, the FAA determined during a flight check inspection that reliable and continuous two-way VHF communications are not possible on the proposed route and withdrawal of the NPRM is warranted.

This action proposes to amend the Class E airspace at Carrington, ND; Cooperstown, ND; Harvey, ND; Rolla, ND; and Walhalla, ND. The FAA is proposing this action due to airspace reviews conducted as part of the decommissioning of the Devils Lake very high frequency (VHF) omnidirectional range (VOR) as part of the VOR Minimal Operational Network (MON) Program. The name of Rolla Municipal Airport/ Leonard Krech Field, Rolla, ND, would also be updated to coincide with the FAA's aeronautical database.

This action proposes to amend the Class E airspace at Hannibal, MO; Monroe City, MO; and Monticello, MO. The FAA is proposing this action as the result of airspace reviews conducted as part of the decommissioning of the Quincy very high frequency (VHF) omnidirectional range (VOR) as part of the VOR Minimal Operational Network (MON) Program. The name of CPT Ben Smith Airfield-Monroe City Airport, Monroe City, MO, would also be updated to coincide with the FAA's aeronautical database.

The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF6-80E1A2, CF6-80E1A3, CF6- 80E1A4, and CF6-80E1A4/B model turbofan engines. This proposed AD was prompted by a manufacturer investigation that revealed that certain compressor discharge pressure seals (CDP seals) and forward outer seals were manufactured from powder metal material suspected to contain iron inclusion. This proposed AD would require the replacement of the affected CDP seals and forward outer seals. The FAA is proposing this AD to address the unsafe condition on these products.

On October 11, 2022, the FAA published a final rule titled ``Update to Investigative and Enforcement Procedures and Part 11; Technical Amendments.'' That document made technical amendments to the Update to Investigative and Enforcement Procedures final rule, which was published on October 1, 2021. The technical amendments rule inadvertently identified the Rulemaking Identification Number (RIN).

This action proposes to amend Class D airspace, Class E surface airspace, and Class E airspace extending upward from 700 feet above the surface in the Greenville, Spartanburg, and Greer, SC areas due to the decommissioning of the Fairmont non-directional beacon (NDB) and cancellation of associated approaches into Spartanburg Downtown Memorial Airport/Simpson Field, as well as updating the airport's name and geographic coordinates. Additionally, Greenville Spartanburg International Airport, Greenville Downtown Airport, and Donaldson Field Airport each require the name and geographic coordinate updates, as well as airspace updates. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

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 reports of potential foreign object debris (FOD) contamination of the thermal relief valve (TRV). This proposed AD would require replacement of affected auxiliary power unit (APU) low pressure (LP) shut-off valves (SOVs), an inspection to detect fuel leaks of affected engine LP SOVs and APU isolation shut-off valves (ISOVs), and applicable corrective actions, and would prohibit 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.
