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 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 Class E airspace relevant to this action are published in paragraphs 5000 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 at Chicago/Rockford, Illinois due to a biennial airspace review conducted pursuant to FAA Order JO 7400.2R.

For the Chicago/Rockford International Airport, Chicago/Rockford, IL, Class D airspace, the proposal would: (1) expand the radius from 4.6 miles to 5.7 miles; and (2) remove the extension south of the airport as it is no longer required.

For the Chicago/Rockford International Airport Class E airspace extending upward from 700 ft. above the surface, the proposal would: (1) increase the radius from 7.1 miles to 8.2 miles; and (2) amend the extension south of the airport to within 4 miles (increased from 3 miles) each side of the 185°bearing from the Chicago/Rockford INTL: RWY 01-LOC extending from the 8.2-mile (currently 7.1-mile) radius of the airport to 11.1 miles (currently 12.3 miles) south of the Chicago/Rockford INTL: RWY 01-LOC.

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) 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 proposed amendments are routine and the expected impact to operators is de minimis, the FAA certifies 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.
