# [Amended]
**AGENCY:**
Federal Aviation Administration (FAA), DOT.
**ACTION:**
Final rule.
**SUMMARY:**
This action amends the Class E airspace at Lacon, IL, and updates the geographic coordinates of the Marshall County Airport, Lacon, IL, to coincide with the FAA's aeronautical database. This action is the result of an airspace review conducted due to the decommissioning of the Bradford very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. It brings the airspace into compliance with FAA orders and supports instrument flight rule (IFR) procedures and operations.
**DATES:**
Effective 0901 UTC, November 27, 2025. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order JO 7400.11 and publication of conforming amendments.

**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 amends the Class E airspace extending upward from 700 feet above the surface at Marshall County Airport, Lacon, IL, to support IFR operations at this airport.
**History**
The FAA published an NPRM for Docket No. FAA-2025-1276 in the *Federal Register* (90 FR 25914; June 18, 2025) proposing to amend the Class E airspace at Lacon, IL. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received.
**Incorporation by Reference**
Class E airspace designations are published in paragraph 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 amends the current version of that order, FAA Order JO 7400.11J, dated July 31, 2024, and effective September 15, 2024. These amendments will be published in the next update to FAA Order JO 7400.11. FAA Order JO 7400.11J, 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 Rule**
This action amends 14 CFR part 71 by modifying the Class E airspace extending from 700 ft above the surface at Marshall County Airport, Lacon, IL: (1) to within a 7-mile (increased from a 6.3-mile) radius of the Marshall County Airport; (2) by updating the geographic coordinates of the airport to coincide with the FAA's aeronautical database; and (3) by removing the city associated with the airport in the airspace legal description to comply with changes to FAA Order JO 7400.2R, Procedures for Handling Airspace Matters.
**Regulatory Notices and Analyses**
The FAA has determined that this 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 only affects air traffic procedures and air navigation, it is certified that this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
**Environmental Review**
The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1F, “Environmental Impacts: Policies and Procedures,” paragraph 5-6.5.a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.
