in the ADDRESSES section of this document. FAA Order 7400.11E lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.
Background The FAA is planning decommissioning activities for the VOR
portion of the Worthington, MN, VOR/
DME with a planned date of March 24, 2022. The Worthington VOR was one of the candidate VORs identified for discontinuance by the FAAs VOR MON
program and listed in the Final policy statement notice, Provision of Navigation Services for the NextGen Transition to Performance-Based Navigation PBN Plan for Establishing a VOR MON, published in the Federal Register of July 26, 2016 81 FR 48694, Docket No. FAA20111082. Although the VOR portion of the Worthington VOR/DME is planned for decommissioning, the co-located DME
portion of the navigational aid is being retained in support of current and future RNAV procedures.
The airways affected by the Worthington VOR are V170, V175, and V250. With the planned decommissioning of the Worthington VOR, the remaining ground-based navigational aid coverage in the area is insufficient to enable the continuity of these affected routes. As such, the proposed modifications would result in the removal of airway segments. To overcome the impacts from the loss of portions of the airways, instrument flight rules IFR traffic may use adjacent airways, including V24, V80, V120, V148, V398, and V456, to navigate through or around the affected areas. IFR traffic could receive air traffic control radar vectors through the areas.
Aircraft equipped with RNAV
capabilities may also file point to point through the affected area using the fixes that will remain in place, or use the proposed new RNAV T400 in lieu of V250. Visual flight rules VFR pilots may utilize the ATC services previously listed.
The proposed new RNAV T-route, T
400, would mitigate the proposed removal of the airway segment of V250
between the Yankton, SD, VOR/DME
and Mankato, MN, VOR/Tactical Air Navigation VORTAC. Additionally, it would provide navigational options in areas of limited or no radar coverage to pilots whose aircraft are RNAV
equipped. Finally, it would support the FAAs efforts to transition the NAS from ground-based to satellite-based navigation.
The FAA proposes to retain all airspace fixes on the deleted segments

of the VOR Federal airways either as fixes or waypoints.
The Proposal The FAA is proposing an amendment to 14 CFR part 71 to amend three VOR
Federal airways and establish one RNAV T-route. The proposed ATS route actions are described below.
V170: V170 extends between the Devils Lake, ND, VOR/DME and the Worthington, MN, VOR/DME; between the Rochester, MN, VOR/DME and the Salem, MI, VORTAC; and between the Slate Run, PA, VORTAC and the intersection of the Andrews, MD, VORTAC 060 radial and the Baltimore, MD, VORTAC 165 radial. The airspace within R5802 is excluded when active.
The FAA proposes to remove the airway segment between the Sioux Falls, SD, VORTAC and the Worthington, MN, VOR/DME. This would result in the first segment of the route extending between the Devils Lake, ND, VOR/DME and the Sioux Falls, SD, VORTAC. The second and third segments of the airway would remain unchanged.
V175: V175 extends between the Malden, MO, VORTAC and the Des Moines, IA, VORTAC; and between the Worthington, MN, VOR/DME and the Alexandria, MN, VOR/DME. The FAA
proposes to remove the airway segment between the Worthington, MN, VOR/
DME and the Redwood Falls, MN, VOR/
DME. This would result in the last segment of the airway extending between the Redwood Falls VOR/DME
and the Alexandria VOR/DME. The first segment of the airway would remain unchanged. Concurrent changes to other segments of V175 have been proposed in a separate rulemaking proposal.
V250: V250 extends between the ONeill, NE, VORTAC and the Mankato, MN, VOR/DME. The FAA proposes to remove the airway segment from the Yankton, SD, VOR/DME and the Mankato, MN, VOR/DME. The resulting airway would extend between the ONeill, NE, VORTAC and the Yankton, SD, VOR/DME.
T400: T400 would be a new RNAV
route that extends between the LLUKY, NE, waypoint WP, located near the ONeill, NE, VORTAC and the ZOSAG, MN, WP, which is a new WP being established near the Flying Cloud, MN, VOR/DME as part of this proposal.
All of the navigational aid radials in the airway descriptions below are stated in True degrees.
Domestic VOR Federal airways and RNAV T-routes are published in paragraphs 6010a and 6011, respectively, of FAA Order 7400.11E, dated July 21, 2020, and effective September 15, 2020, which are

incorporated by reference in 14 CFR
71.1. The ATS routes listed in this document would be published subsequently in the Order.
FAA Order 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.
