# 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

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-2022-0172; Airspace Docket No. 22-AAL-3) 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-2022-0172; Airspace Docket No. 22-AAL-3.” 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                           ( print page 13666)                        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

The aviation industry/users have indicated a desire for the FAA to transition the Alaskan en route navigation structure away from the dependency on NDBs. The advances in technology have allowed for alternate navigation methods to support decommissioning of high cost ground navigation equipment. The FAA has included EAV on their schedule to be decommissioned effective February 23, 2023. A non-rulemaking study was conducted in accordance with FAA Order JO 7400.2, Procedures for Handling Airspace Matters. As a result, the FAA received no objections to its removal.

Colored Federal airways A-5 and B-4 are dependent upon EAV and will result in the airways being unusable once the decommissioning occurs. The FAA is proposing to revoke A-5 and B-4 as a result. The revocation of A-5 is mitigated by United States Area Navigation (RNAV) route T-233 that currently overlays the route. To mitigate the loss of B-4, the FAA has a planned RNAV route T-374.

## The Proposal

The FAA is proposing an amendment to 14 CFR part 71 to revoke Colored Federal airways A-5 and B-4 due to the decommissioning of EAV.

*A-5:*                     A-5 currently navigates between the Ambler, AK, NDB and the Evansville, AK, NDB. The FAA proposes to revoke the route in its entirety.                

*B-4:*                     B-4 currently navigates between the Utopia Creek, AK, NDB via the Evansville, AK, NDB to the Yukon River, AK, NDB. The FAA proposes to revoke the route in its entirety.                

Colored Federal airways are published in paragraph 6009(c) and 6009(d) 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 Colored Federal airways 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.
