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 route structure to maintain the 
efficient flow of air traffic within the NAS.

History

    The FAA published a NPRM for Docket No. FAA-2026-1062 in the 
Federal Register (91 FR 3696; January 28, 2026), proposing to amend 
RNAV Route T-437 in the eastern United States. Interested parties were 
invited to participate in this rulemaking effort by submitting written 
comments on the proposal to the FAA. Two comments were received. The 
first comment was supportive of the amendment and the second comment 
was not germane to the amendment of RNAV Route T-437.

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 amends the current version of that order, FAA 
Order JO 7400.11M, dated July 30, 2026, and effective September 15, 
2026. These amendments will 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.

The Rule

    This action amends 14 CFR part 71 by amending RNAV Route T-437 in 
the eastern United States. This action supports the FAA's NextGen 
efforts to provide a modern RNAV route structure to improve the safety 
and efficiency of the NAS. The amendments are described below.
    T-437: Prior to this final rule, T-437 extended between the SIROC, 
GA, waypoint (WP) and the ZOOMS, WV, Fix. The FAA is extending the 
airway to the north between the ZOOMS Fix and the Elkins, WV (EKN), 
Very High Frequency Omnidirectional Range/Tactical Air Navigation 
(VORTAC) to provide connectivity for RNAV-equipped aircraft between the 
Zenith, WV, and the Elkins, WV, areas. As amended, the route is changed 
to now extend between the SIROC WP and the Elkins VORTAC.

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 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 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 airspace action of amending RNAV 
Route T-437 in the eastern United States qualifies for categorical 
exclusion under the National Environmental Policy Act (42 U.S.C. 4321 
et seq.) and in accordance with 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(b), which categorically 
excludes from further environmental impact review ``Actions regarding 
establishment of jet routes and Federal airways (see 14 CFR 71.15, 
Designation of jet routes and VOR Federal airways). . .''. As such, 
this action is not expected to result in any potentially significant 
environmental impacts. In accordance with the FAA's NEPA implementation 
policy and procedures regarding extraordinary circumstances, the FAA 
has reviewed this action for factors and circumstances in which a 
normally categorically excluded action may have a significant 
environmental impact requiring further analysis. The FAA has determined 
that no extraordinary circumstances exist that warrant preparation of 
an environmental assessment or environmental impact statement.
