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>.
Availability of Rulemaking Documents
An electronic copy of this document may be downloaded through the
internet at <a href="http://www.regulations.gov">www.regulations.gov</a>. Recently published rulemaking
documents can also be accessed through the FAA's web page at

You may review the public docket containing the proposal, any
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 Western Service Center,
Federal Aviation Administration, 2200 South 216th St., Des Moines, WA

Incorporation by Reference
Canadian Area Navigation Routes are published in paragraph 2007 and
Jet Routes are published in paragraph 2004 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 7400.11K, dated
August 4, 2025, and effective September 15, 2025. These updates would
be published in the next update to FAA Order JO 7400.11. FAA Order JO
7400.11K, 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
The proposed actions are necessary to accommodate Nav Canada's
multi-year ongoing NAVAID Modernization Plan (NMP), which reduces
reliance upon ground-based navigation aids (NAVAIDs) and transitions to
a more efficient and cost-effective system using satellite/Performance
Based Navigation (PBN). This shift away from ground-based NAVAIDs
impacts the existing cross-border U.S. Federal Airway structure, and
the FAA is proposing these actions to provide enroute continuity with
NAV Canada's ongoing route structure modernization efforts.
Q-838 would replace J-539, which is currently NOTAM'd out of
service due to the decommissioning of the Swift Current, SK, Canada,
Very High Frequency Omnidirectional Range/Distance Measuring Equipment
(VOR/DME). Q-838 would connect with NAV Canada's existing Q-838 at the
new CAYUS, MT, Waypoint (WP) located on the U.S./Canadian border. The
current computer navigation fix, CFWVQ, would also be removed from the
database.
The Proposal
The FAA is proposing an amendment to 14 CFR part 71 to establish
Canadian Area Navigation (RNAV) Route Q-838 and revoke Jet Route J-539
in the vicinity of Glasgow, MT.
Q-838: Q-838 would extend between the Glasgow, MT, VOR/Distance
Measuring Equipment (DME) and the CAYUS, MT, WP.
J-539: J-539 currently extends between the Glasgow, MT, VOR/DME and
the Swift Current, SK, Canada, VOR. The FAA is proposing to revoke J-
539 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 DOT
Order 2100.6B,
[[Page 25158]]
``Rulemaking and Guidance Procedure'' (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.
