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 remove 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.

Incorporation by Reference

Class D and E airspace relevant to this action are published in paragraphs 5000, 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 and Class E airspace extending upward from 700 ft. above the surface and remove the Class E airspace area designated as an extension to Class D airspace at Muncie, Indiana due to an airspace review conducted as part of the decommissioning of the Muncie VOR as part of the VOR MON Program; and remove the Class E airspace extending upward from 700 ft. above the surface at Alexandria, Indiana due to the cancellation of the instrument procedures and the airspace no longer being required.

For the Delaware County Regional Airport, Muncie, IN, Class D airspace, the proposal would: (1) increase the radius from 4.4 to 4.7 miles; (2) remove the city associated with the airport in the header of the airspace legal description to comply with changes to FAA Order JO 7400.2R, Procedures for Handling Airspace Matters; (3) update the geographic coordinates and name of Delaware County Regional Airport (previously Delaware County-Johnson Field) to coincide with the FAA's aeronautical database; and (4) update the outdated term “Airport/Facility Directory” to “Chart Supplement.”

The proposal would remove the Class E airspace designated as an extension to Class D airspace at Delaware County Regional Airport as it is no longer required.

The proposal would remove Class E airspace extending upward from 700 ft. above the surface at Alexandria Airport, Alexandria, IN, as the instrument procedures have been cancelled and the airspace is no longer required.

And for the Delaware County Regional Airport Class E airspace extending upward from 700 ft. above the surface, the proposal would: (1) increase the radius from 7 to 7.2 miles; and (2) remove the city associated with the airports from the header of the airspace legal description to comply with changes to FAA Order JO 7400.2R.

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 Order 2100.6B, “Policies and Procedures for Rulemakings” (March 10, 2025); 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.

The Proposed Amendment

In consideration of the foregoing, the Federal Aviation Administration proposes to amend 14 CFR part 71 as follows:

2. The incorporation by reference in 14 CFR 71.1 of FAA Order JO 7400.11K, Airspace Designations and Reporting Points, dated August 4, 2025, and effective September 15, 2025, is amended as follows:
