Abstract
This action proposes to amend the Class D and Class E airspace and revoke Class E airspace at Fort Knox, KY. The FAA is proposing this action as the result of a biennial airspace review conducted due to the decommissioning of the Godman non-directional beacon (NDB). The geographic coordinates of Godman AAF (Army Air Field), Fort Knox, KY, would also be updated to coincide with the FAA's aeronautical database. This action would bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.

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
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 Class D and Class E airspace and revoke Class E
airspace at the affected airport to support IFR operations.
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 received 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-14FDMS), 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
<a href="http://www.faa.gov/air_traffic/publications/airspace_amendments/">www.faa.gov/air_traffic/publications/airspace_amendments/</a>.
You may review the public docket containing the proposal, any
comments received, and any final disposition in person in the Dockets
Office (see the ADDRESSES section for the address, phone number, and
hours of operations). An informal docket may also be examined during
normal business hours at the Federal Aviation Administration, Air
Traffic Organization, Central Service Center, Operations Support Group,

Incorporation by Reference
Class D and E airspace relevant to this action are published in
paragraphs 5000, 6002, 6004, and 6005 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.
The Proposal
The FAA is proposing an amendment to 14 CFR part 71 that would
modify the Class D airspace, Class E surface airspace, and Class E
airspace extending upward from 700 ft. above the surface, and revoke
the Class E airspace designated as an extension to Class D and Class E
surface areas at Fort Knox, KY, due to a biennial airspace review due
to the decommissioning of the Godman NDB.
For the Godman AAF, Fort Knox, KY, Class D airspace, the proposal
would: (1) increase the radius from 3.9 miles to 4.6 miles; (2) update
the geographic coordinates of the airport to coincide with the FAA's
aeronautical database; and (3) remove the unnecessary language,
``(previously called Airport/Facility Directory)'' from the airspace
legal description.
For the Godman AAF Class E surface area, the proposal would: (1)
increase the radius from 3.9 miles to 4.6 miles; (2) update the
geographic coordinates of the airport to coincide with the FAA's
aeronautical database; and (3) remove the unnecessary language,
``(previously called Airport/Facility Directory)'' from the airspace
legal description.
For the Godman AAF Class E airspace designated as an extension to
Class D and Class E surface areas, the proposal would revoke the
airspace as it is no longer required.
For the Godman AAF Class E airspace extending upward from 700 ft.
above the surface, the proposal would: (1) increase the radius from
6.3-miles to 7 miles; (2) remove the Godman NDB and associated
extension from the airspace legal description as the NDB has been
decommissioned and the extension is no longer required; and (3) update
the geographic coordinates of the airport to coincide with the FAA's
aeronautical database.
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
[[Page 12516]]
rule'' under 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 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.
