Department of Transportation November 12, 2021 – Federal Register Recent Federal Regulation Documents

The Federal Transit Administration (FTA) announces the opportunity to apply for a total of $2,000,000 in competitive cooperative agreement awards in fiscal year (FY) 2021 funds for projects that enhance mobility innovations for transit. Funds will be awarded competitively for projects that advance emerging technologies, strategies and innovations in passenger-centric mobility in two distinct areas. Of the total available funds, $1,000,000 is available to accelerate innovative mobility and is for projects to improve mobility and enhance the rider experience with a focus on innovative service delivery models, creative financing, novel partnerships, and integrated payment solutions; and $1,000,000 is available for projects to support the development of software solutions that facilitate the provision of integrated demand-response public transportation service that dispatches public transportation fleet vehicles through riders mobile devices or other means. Projects will be competitively selected based on criteria outlined in this notice. FTA may award additional funding that is made available to the program prior to the announcement of project selections.

In compliance with the Paperwork Reduction Act of 1995, this notice announces that the Information Collection Request (ICR) summarized below will be submitted to the Office of Management and Budget (OMB) for review and approval. The ICR describes the nature of the information collection, Vehicle Information for the General Public, and its expected burden. A Federal Register Notice with a 60-day comment period soliciting comments on the information collection was published on July 7, 2020. One comment was received in general support of this collection request.

This action proposes to establish United States Area Navigation (RNAV) route T-374 in the vicinity of Kotzebue, AK in support of a large and comprehensive T-route modernization project for the state of Alaska.

This action proposes to amend the VHF Omnidirectional Range (VOR) Federal airways V-26, V-193, and V-285, and revoke the White Cloud, MI, domestic low altitude reporting point. The FAA is proposing this action due to the planned decommissioning of the VOR portion of the White Cloud, MI, VOR/Distance Measuring Equipment (VOR/DME) navigational aid (NAVAID). The White Cloud VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.

The FAA is superseding Airworthiness Directive (AD) 2021-05-16 for certain Pratt & Whitney Division (PW) PW4164, PW4164-1D, PW4168, PW4168-1D, PW4168A, PW4168A-1D, and PW4170 model turbofan engines. AD 2021-05-16 required initial and repetitive replacements of the low- pressure turbine (LPT) 4th-stage air sealing ring segment assemblies with parts eligible for installation. AD 2021-05-16 also required initial and repetitive dimensional inspections of the LPT case for bulging and, depending on the results of the dimensional inspections, repair or replacement of the LPT case. This AD was prompted by notification to the FAA of an inadvertent omission in the LPT 4th-stage air sealing ring segment assembly part numbers. This AD requires initial and repetitive replacements of the LPT 4th-stage air sealing ring segment assemblies with parts eligible for installation. This AD also requires initial and repetitive dimensional inspections of the LPT case for bulging and, depending on the results of the dimensional inspections, repair or replacement of the LPT case. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is removing Airworthiness Directive (AD) 2021-05-02, which applied to all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, and AS350D helicopters; Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters; and Model EC130B4 and EC130T2 helicopters. AD 2021-05-02 required determining whether the helicopter has been operated in a severe environment since the last inspection of the main rotor hub-to-mast attachment screws, an inspection of the main rotor hub-to-mast attachment screws if the helicopter has been operated in a severe environment, and replacement of the main rotor hub-to-mast attachment screws if necessary, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which was incorporated by reference. Since the FAA issued AD 2021-05- 02, reported inspection results and further investigation have confirmed that the report of failed main rotor hub-to-mast attachment screws, which prompted AD 2021-05-02, was an isolated case which resulted from a maintenance mistake. Therefore, the FAA has determined that no unsafe condition is likely to exist or develop on the main rotor hub-to-mast attachment screws on other helicopters in the fleet. Accordingly, AD 2021-05-02 is removed.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12/47E airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as inward vent valves installed during production without chromate conversion coating on the bonding surface. This proposed AD would require modifying the inward vent valves and prohibiting installation of unmodified inward vent valves. 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 Leonardo S.p.a. Model AB139 and AW139 helicopters. This proposed AD was prompted by the identification of certain parts needing maintenance actions, including life limits and maintenance tasks. This proposed AD would require incorporating into maintenance records requirements (airworthiness limitations), as specified in a European Aviation Safety Agency (now 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 the Class E airspace extending upward from 700 feet above the surface at Frankfort Dow Memorial Field, Frankfort, MI. This action is the result of an airspace review caused by the decommissioning of the Manistee 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 are also being updated to coincide with the FAA's aeronautical database.

This action proposes to amend the Class D and Class E airspace at Janesville, WI. The FAA is proposing this action as the result of an airspace review caused by the decommissioning of the Rockford 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 would also be updated to coincide with the FAA's aeronautical database.

This action proposes to amend the Class D and Class E airspace at Rochester International Airport, Rochester, MN, and St. Cloud Regional Airport, St. Cloud, MN, and revoke Class E airspace at Rochester International Airport. The FAA is proposing this action as the result of biennial airspace reviews. The geographic coordinates of St. Cloud Regional Airport would also be updated to coincide with the FAA's aeronautical database.

This action proposes to amend the Class E airspace at Glass Ranch Airport, Carrizo Spring, TX. The FAA is proposing this action as the result of the cancellation of the instrument procedures and closure of the airport. The geographic coordinates of the Indio-Faith Airport, Carrizo Spring, TX, would also be updated to coincide with the FAA's aeronautical database.
