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

[[Page 2371]]

expand the availability of RNAV in Alaska and improve the efficient 
flow of air traffic within the National Airspace System (NAS) by 
lessening the dependency on ground based navigation.

Comments Invited

    Interested parties are invited to participate in this proposed 
rulemaking by submitting such written data, views, or arguments as they 
may desire. Comments that provide the factual basis supporting the 
views and suggestions presented are particularly helpful in developing 
reasoned regulatory decisions on the proposal. Comments are 
specifically invited on the overall regulatory, aeronautical, economic, 
environmental, and energy-related aspects of the proposal.
    Communications should identify both docket numbers (FAA Docket No. 
FAA-2021-1194; Airspace Docket No. 19-AAL-39) and be submitted in 
triplicate to the Docket Management Facility (see ADDRESSES section for 
address and phone number). You may also submit comments through the

Availability and Summary of Documents for Incorporation by Reference

    This document proposes to amend FAA Order JO 7400.11F, Airspace 
Designations and Reporting Points, dated August 10, 2021, and effective 
September 15, 2021. FAA Order JO 7400.11F is publicly available as 
listed in the ADDRESSES section of this document. FAA Order JO 7400.11F 
lists Class A, B, C, D, and E airspace areas, air traffic service 
routes, and reporting points.


    In 2003, Congress enacted the Vision 100-Century of Aviation 
Reauthorization Act (Pub L., 108-176), which established a joint 
planning and development office in the FAA to manage the work related 
to the Next Generation Air Transportation System (NextGen). Today, 
NextGen is an ongoing FAA-led modernization of the nation's air 
transportation system to make flying safer, more efficient, and more 
    In support of NextGen, this proposal is part of a larger and 
comprehensive T-route modernization project in the state of Alaska. The 
project mission statement states: ``To modernize Alaska's Air Traffic 
Service route structure using satellite based navigation Development of 
new T-routes and optimization of existing T-routes will enhance safety, 
increase efficiency and access, and will provide en route continuity 
that is not subject to the restrictions associated with ground based 
airway navigation.'' As part of this project, the FAA evaluated the 
existing Colored Airway structure for: (a) Direct replacement (i.e., 
overlay) with a T-route that offers a similar or lower Minimum En route 
Altitude (MEA) or Global Navigation Satellite System Minimum En route 
Altitude (GNSS MEA); (b) the replacement of the Colored airway with a 
T-route in an optimized but similar geographic area, while retaining 
similar or lower MEA; or (c) removal with no route structure (T-route) 
restored in that area because the value was determined to be 
    The aviation industry/users have indicated a desire for the FAA to 
transition the Alaskan en route navigation structure away from 
dependency on Non-Directional Beacons (NDB), and move to develop and 
improve the RNAV route structure. The FAA proposes to establish RNAV 
route T-370 between Port Heiden Airport (PTH), Alaska and the Kenai, 
AK, (ENA) VHF Omnidirectional Radar/Distance Measuring Equipment (VOR/
DME). The intent of this proposal is to support future decommissioning 
of the Port Heiden, AK, (PDN); Wood River, AK, (BTS); and Iliamna, AK, 
(ILI) NDBs. The proposed route would provide an alternative to G-1, V-
351, and V-457 with lower GNSS MEAs, while ensuring continuous two-way 
VHF communications throughout. Finally, the proposed route would 
provide instrument approach procedures connectivity to PTH.

The Proposal

    The FAA is proposing an amendment to 14 CFR part 71 to establish 
RNAV route T-370 in the vicinity of Kenai, AK in support of a large and 
comprehensive T-route modernization project for the state of Alaska. 
The proposed route is described below.
    T-370: The FAA proposes to establish T-370 from the newly 
established WIXER, AK, waypoint (WP), located over Port Heiden Airport 
to the Kenai, AK, (ENA) VOR/DME. The full legal description is included 
in ``The Proposed Amendment'' section below.
    United States Area Navigation Routes are published in paragraph 
6011 of FAA Order JO 7400.11F dated August 10, 2021, and effective 
September 15, 2021, which is incorporated by reference in 14 CFR 71.1. 
The RNAV listed in this document would be published subsequently in FAA 
Order JO 7400.11.
    FAA Order JO 7400.11, Airspace Designations and Reporting Points, 
is published yearly and effective on September 15.

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 
Department of Transportation (DOT) Regulatory Policies and Procedures 
(44 FR 11034; February 26, 1979); 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 
procedures and air navigation, it is

[[Page 2372]]

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 1050.1F, ``Environmental Impacts: Policies 
and Procedures'' prior to any FAA final regulatory action.
