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 amend the airway structure as necessary to
preserve the safe and efficient flow of air traffic within the National
Airspace System.
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. DOT posts
these comments, without edit, including any personal information the
commenter provides, to <a href="http://www.regulations.gov">www.regulations.gov</a>, as described in the system
of records notice (DOT/ALL-14 FDMS), which can be reviewed at
<a href="http://www.dot.gov/privacy">www.dot.gov/privacy</a>.

comments received and any final disposition in person in the Dockets
Operations office (see ADDRESSES section for address, phone number, and
hours of operations). An informal docket may also be examined during
normal business hours at the office of the Operations Support Group,
Central Service Center, Federal Aviation Administration, 10101 Hillwood
Parkway, Fort Worth, TX, 76177.
Incorporation by Reference
United States RNAV Routes are published in paragraph 6011 and VOR
Federal Airways are published in paragraph 6010 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
document proposes to amend the current version of that order, FAA Order
JO 7400.11M, dated July 30, 2026, and effective September 15, 2026.
These updates would be published in the next update to FAA Order JO
7400.11. FAA Order JO 7400.11M, which lists Class A, B, C, D, and E
airspace areas, air traffic service routes, and reporting points, is
publicly available as listed in the ADDRESSES section of this document.
Background
Hailey, ID, NDB/DME (HLE) is scheduled to be decommissioned on
April 15, 2027. Due to maintenance issues, HLE has been out of service
since January 2023. Historically utilized by Friedman Memorial Airport
(KSUN) for backup departure procedures, HLE saw minimal operational
use, a decline driven largely by the availability of alternative
departure routes, even prior to its scheduled decommission. The loss of
this Navigational Aid (NAVAID) will affect VOR federal airways V-101
between the Burley, ID, VOR/DME and the SOLDE, ID, Fix and V-484
between HLE and the JEROT, ID, Fix. The establishment of RNAV Route T-
337 is proposed as a mitigation to the affected segments of V-484 as
the new RNAV route would overlay the segment of V-484 proposed to be
revoked. Nearby V-444 would mitigate the loss of the impacted segment
of V-101.
The Proposal
The FAA is proposing an amendment to 14 CFR part 71 to establish
RNAV route T-337 and amend VOR federal airways V-101 and V-484 near
Twin Falls, ID.
T-337: T-337 is proposed as a new RNAV route that would extend
between the Twin Falls, ID, VOR/Tactical Air Navigation (VORTAC) and
the ENDBE, ID, Waypoint (WP). The waypoint ENDBE is a new waypoint that
would be established in place of the Hailey NDB/DME.
V-101: V-101 currently extends between the Gill, CO, VOR/DME and
the intersection of the Pocatello, ID, VOR/DME 286 and the Twin Falls
VORTAC 355 radials. The FAA is proposing to revoke the segment that
extends between the intersection of the Burley, ID, VOR/DME 344 and the
Pocatello VOR/DME 286 radials and the intersection of the Pocatello,
ID, VOR/DME 286 and the Twin Falls VORTAC 355 radials. As amended, V-
101 would extend between the Gill VOR/DME and the Burley VOR/DME.
V-484: V-484 currently extends between the Hailey, ID, NDB and the
Alamosa, CO, VORTAC. The FAA is proposing to revoke the segment that
extends between the Hailey NDB and the intersection of the Twin Falls
VORTAC 007 and Burley VOR/DME 323 radials. As amended, V-484 would
extend between the intersection of the Twin Falls VORTAC 007 and the
Burley VOR/DME 293 radials and the Alamosa VORTAC.

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 DOT
Order 2100.6B, ``Rulemaking and Guidance Procedures'' (March 10, 2025);
and (3) is expected to result in, at most, de minimis costs from
compliance with applicable operating requirements or minor flight
rerouting for operators choosing to navigate around the controlled
airspace. Since these proposed amendments are routine and the expected
impact to operators is de minimis, the FAA certifies 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 1050.1G, ``FAA National Environmental Policy
Act Implementing Procedures'' prior to any FAA final regulatory action.
