FAA Proposes Amending Airspace at Fort Knox, KY

Content

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

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.

DATES:

Comments must be received on or before April 30, 2026.

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 www.regulations.gov as described in the system of records notice (DOT/ALL-14FDMS), which can be reviewed at www.dot.gov/privacy.

Availability of Rulemaking Documents

An electronic copy of this document may be downloaded through the internet at www.regulations.gov. Recently published rulemaking documents can also be accessed through the FAA's web page at www.faa.gov/air_traffic/publications/airspace_amendments/.

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

  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.
