# 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 modify the route structure as necessary to preserve the safe and efficient flow of air traffic within the National Airspace System (NAS).

## Comments Invited

The FAA invites interested persons to participate in this rulemaking by submitting written comments, data, or views. Comments are specifically invited on the overall regulatory, aeronautical, economic, environmental, and energy-related aspects of the proposal. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should submit only one time if comments are filed electronically, or commenters should send only one copy of written comments if comments are filed in writing.

The FAA will file in the docket all comments it receives, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, the FAA will consider all comments it receives on or before the closing date for comments. The FAA will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. The FAA may change this proposal in light of the comments it receives.

*Privacy:*                     In accordance with 5 U.S.C. 553(c), DOT solicits comments from the public to better inform its rulemaking process.

## Incorporation by Reference

                    Colored Federal airways are published in paragraph 6009 of FAA Order JO 7400.11, Airspace Designations and Reporting Points, which is incorporated by reference in 14 CFR 71.1 on an annual basis. This                           ( print page 88284)                        document proposes to amend the current version of that order, FAA Order JO 7400.11H, dated August 11, 2023, and effective September 15, 2023. These updates would be published in the next update to FAA Order JO 7400.11. That order is publicly available as listed in the                     **ADDRESSES**                     section of this document.                

FAA Order JO 7400.11H 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 an ongoing, large, 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 en route 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 En route Altitude (MEA) or Global Navigation Satellite System (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 Nondirectional Radio Beacons (NDB) and move to develop and improve the United States Area Navigation (RNAV) route structure.

Colored Federal airway A-1 extends between the Abbotsford, British Columbia (BC), Canada and Orca Bay, AK, NDBs; and between the Takotna River, AK, and Fort Davis, AK, NDBs, excluding the airspace within Canada. The Orca Bay, Ocean Cape, Sitka, Takotna River, North River, and Fort Davis NDBs are scheduled for decommissioning. The FAA is proposing to revoke Colored Federal airway A-1 in its entirety due to its supporting NAVAIDs being decommissioned.

The loss of the segment extending between the Abbotsford and Orca Bay NDBs is mitigated by Area Navigation (RNAV) route T-269 and Alaskan Very High Frequency Omnidirectional Range (VOR) Federal Airways V-319 and V-440.

The loss of the segment of extending between the Takotna River and Fort Davis NDBs is mitigated by Alaskan VOR Federal Airway V-440.

## The Proposal

The FAA is proposing an amendment to 14 CFR part 71 to revoke Colored Federal airway A-1 in Alaska due to the pending decommissioning of its supporting NAVAIDs.

Colored Federal airway A-1 extends between the Abbotsford, BC, Canada and Orca Bay, AK, NDBs and between the Takotna River, AK, and Fort Davis, AK, NDBs, excluding the airspace within Canada. The FAA proposes to revoke Colored Federal airway A-1 in its entirety.

## 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.
