SUPPLEMENTARY INFORMATION: Authority for This Rulemaking The FAA's authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, Section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency's authority. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it would expand the availability of RNAV in Alaska and improve the efficient flow of air traffic within the National Airspace System (NAS) by lessoning the dependency on ground based navigation. Comments Invited Interested parties are invited to participate in this proposed rulemaking by submitting such written data, views, or arguments as they may desire. Comments that provide the factual basis supporting the views and suggestions presented are particularly helpful in developing reasoned regulatory decisions on the proposal. Comments are specifically invited on the overall regulatory, aeronautical, economic, environmental, and energy-related aspects of the proposal. Communications should identify both docket numbers (FAA Docket No. FAA-2022-0245; Airspace Docket No. 19-AAL-49) and be submitted in triplicate to the Docket Management Facility (see 
                    **ADDRESSES**
                     section for address and phone number). You may also submit comments through the internet at 
                    *https://www.regulations.gov.* Commenters wishing the FAA to acknowledge receipt of their comments on this action must submit with those comments a self-addressed, stamped postcard on which the following statement is made: “Comments to FAA Docket No. FAA-2022-0245; Airspace Docket No. 19-AAL-49.” The postcard will be date/time stamped and returned to the commenter. All communications received on or before the specified comment closing date will be considered before taking action on the proposed rule. The proposal contained in this action may be changed in light of comments received. All comments submitted will be available for examination in the public docket both before and after the comment closing date. A report summarizing each substantive public contact with FAA personnel concerned with this rulemaking will be filed in the docket.

Availability and Summary of Documents for Incorporation by Reference This document proposes to amend FAA Order JO 7400.11F, Airspace Designations and Reporting Points, dated August 10, 2021, and effective September 15, 2021. FAA Order JO 7400.11F is publicly available as listed in the 
                    **ADDRESSES**
                     section of this document. FAA Order JO 7400.11F lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points. Background In 2003, Congress enacted the Vision 100—Century of Aviation Reauthorization Act (Pub. L. 108-176), which established a joint planning and development office in the FAA to manage the work related to the Next Generation Air Transportation System (NextGen). Today, NextGen is an ongoing FAA-led modernization of the nation's air transportation system to make flying safer, more efficient, and more predictable. In support of NextGen, this proposal is part of a larger and comprehensive T-route modernization project in the state of Alaska. The project mission statement states: “To modernize Alaska's Air Traffic Service route structure using satellite based navigation Development of new T-routes and optimization of existing T-routes will enhance safety, increase efficiency and access, and will provide enroute continuity that is not subject to the restrictions associated with ground based airway navigation.” As part of this project, the FAA evaluated the existing Colored airway structure for: (a) Direct replacement (
                    *i.e.,*
                     overlay) with a T-route that offers a similar or lower Minimum Enroute Altitude (MEA) or Global Navigation Satellite System Minimum Enroute Altitude (GNSS MEA); (b) the replacement of the Colored airway with a T-route in an optimized but similar geographic area, while retaining similar or lower MEA; or (c) removal with no route structure (T-route) restored in that area because the value was determined to be insignificant. The aviation industry/users have indicated a desire for the FAA to transition the Alaskan en route navigation structure away from dependency on Non-Directional Beacons (NDB), and move to develop and improve the RNAV route structure. St. Marys, AK (SMA), Aniak, AK (ANI), and Cairn Mountain, AK (CRN) NDBs are all included on the schedule to be decommissioned. Colored Federal airway Green 6 (G-6) is dependent upon SMA and ANI for navigation and the decommissioning would render it unusable. To mitigate the loss of G-6, this proposal would establish RNAV route T-380 that would overlay the current G-6. Additionally, in order to provide an alternative to VHF Omnidirectional Radar (VOR) Federal airway V-508, this proposal would allow for a lower GNSS MEA and still provide the appropriate separation along the southwest portion of Stony MOA from Aniak, AK to Sparrevohn, AK. Finally, the proposal would provide RNAV route connectivity with T-225 to the southeast of Emmonak, AK at a newly established waypoint (WP) HUMLA.
                    ( print page 16681) The Proposal The FAA is proposing an amendment to 14 CFR part 71 to establish RNAV route T-380 in the vicinity of Emmonak, AK in support of a large and comprehensive T-route modernization project in the state of Alaska. The proposed route is described below. *T-380:*
                     The FAA proposes to establish RNAV route T-380 from the Emmonak, AK, (ENM) VOR/Distance Measuring Equipment (VOR/DME) to the Sparrevohn, AK, (SQA) VOR/DME, due to the decommissioning of SMA, ANI, and CRN NDBs. United States Area Navigation Routes are published in paragraph 6011 of FAA Order JO 7400.11F dated August 10, 2021 and effective September 15, 2021, which is incorporated by reference in 14 CFR 71.1. The RNAV route listed in this document would be published subsequently in FAA Order JO 7400.11. FAA Order JO 7400.11, Airspace Designations and Reporting Points, is published yearly and effective on September 15. Regulatory Notices and Analyses The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore: (1) Is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under Department of Transportation (DOT) Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. Environmental Review This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1F, “Environmental Impacts: Policies and Procedures” prior to any FAA final regulatory action.
