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>.

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 Central Service Center,
Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX

Incorporation by Reference
United States Area Navigation Routes are published in paragraph
6011 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 FAA is proposing to establish: (1) RNAV Route T-583 that would
extend between the Laredo (LRD), TX, Very High Frequency
Omnidirectional Range/Tactical Air Navigation (VORTAC) and the Waco
(ACT), TX, VORTAC; and (2) RNAV Route T-585 that would extend between
the Corpus Christi (CRP), TX, VORTAC and the Waco, TX, VORTAC. RNAV
Route T-583 would bypass Austin Terminal Radar Approach Control
(TRACON) airspace on the west side, and RNAV Route T-585 would bypass
Austin TRACON airspace on the east side. These routes would provide
users a more direct and efficient route structure while reducing the
volume of low altitude aircraft that routinely overfly the Austin
Terminal area, creating potential conflicts with aircraft arriving and
departing from AUS. The northern portion of both routes will assist
with feeding arrival traffic into Austin TRACON airspace and will
facilitate revised arrival procedures within the Austin Terminal area.
The Proposal
The FAA is proposing an amendment to 14 CFR part 71 to establish
RNAV Routes T-583 and T-585 in Texas.
T-583: T-583 would extend between the Laredo (LRD), TX VORTAC and
the Waco (ACT), TX VORTAC.
T-585: T-585 would extend between the Corpus Christi (CRP), TX
VORTAC and the Waco (ACT), TX 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 Procedure'' (March 10, 2025);
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
[[Page 21751]]
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 1050.1G, ``FAA National Environmental Policy
Act Implementing Procedures'' prior to any FAA final regulatory action.
