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 modifies the Air Traffic Services (ATS) route structure
as necessary to preserve the safe and efficient flow of air traffic
within the National Airspace System.
History
The FAA published an NPRM for Docket No. FAA-2026-0859 in the
Federal Register (91 FR 3698; January 28, 2026), proposing to amend
RNAV Route T-373 in the vicinity of King Salmon, Alaska. Interested
parties were invited to participate in this rulemaking effort by
submitting written comments on the proposal to the FAA. No comments
were received.
Incorporation by Reference
RNAV 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 amends the current version of that order, FAA Order JO
7400.11K, dated August 4, 2025, and effective September 15, 2025. These
amendments will 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.
The Rule
The FAA is amending 14 CFR part 71 by modifying RNAV Route T-373 in
the vicinity of King Salmon, Alaska.
T-373: Prior to this final rule, T-373 extended between the Kowok,
AK, Fix and the Werel, AK, waypoint (WP). The FAA is extending the
airway to the King Salmon, AK, Very High Frequency Omnidirectional
Range Tactical Air Navigation (VORTAC). As amended, T-373 extends
between the King Salmon VORTAC and the Werel WP.
Regulatory Notices and Analyses
The FAA has determined that this 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) 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 amendments are routine and the expected impact to
operators is de minimis, the FAA certifies that this rule, when
promulgated, does not have a significant economic impact on a
substantial number of small entities under the criteria of the
Regulatory Flexibility Act.
Environmental Review
The FAA has determined that this action of amending RNAV Route T-
373 qualifies for categorical exclusion under the National
Environmental Policy Act (42 U.S.C. 4321, et seq.) and FAA Order
1050.1G, FAA National Environmental Policy Act Implementing Procedures,
paragraph B-2.5(a) which categorically excludes from further
environmental impact review rulemaking actions that designate or modify
classes of airspace areas, airways, routes, and reporting points (see
14 CFR part 71, Designation of Class A, B, C, D, and E Airspace Areas;
Air Traffic Service Routes; and Reporting Points); and paragraph B-
2.5(i), which categorically excludes from further environmental impact
review the establishment of new or revised air traffic control
procedures conducted at 3,000 feet or more above ground level (AGL);
procedures conducted below 3,000 feet AGL that do not cause traffic to
be routinely routed over noise sensitive areas; modifications to
currently approved procedures conducted below 3,000 feet AGL that do
not significantly increase noise over noise sensitive areas; and
increases in minimum altitudes and landing minima. As such, this action
is not expected to result in any potentially significant environmental
impacts. Additionally, in accordance with Appendix B, paragraph B-1 of
FAA Order 1050.1G, the FAA has determined that no extraordinary
circumstances exist that warrant preparation of an environmental
assessment or environmental impact statement.
