Modification of Class D and E Airspace; Bozeman Yellowstone International Airport, Bozeman, MT
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule.
SUMMARY:
This action modifies the Class D surface area airspace, Class E airspace area designated as surface area, Class E airspace area designated as an extension to a Class D or Class E surface area, and the Class E airspace area extending upward from 700 feet above the surface of the earth at Bozeman Yellowstone International Airport, Bozeman, MT. These actions support the safety and management of visual flight rules (VFR) and instrument flight rules (IFR) operations at the airport.
DATES:
Effective date 0901 UTC, August 7, 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 the 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 modifies Class D and Class E airspace to support VFR and IFR operations at Bozeman Yellowstone International Airport, Bozeman, MT.
History
The FAA published a notice of proposed rulemaking for Docket No. FAA-2023-2423 in the Federal Register (90 FR 8001; January 23, 2025), proposing to modify Class D and Class E airspace at Bozeman Yellowstone International Airport, Bozeman, MT. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. Three comments were received. Two comments were in favor of the proposal and one comment was not germane to the airspace action.
Differences From the NPRM
Subsequent to the publication of the NPRM and effective February 10, 2025, the FAA's definition of the acronym "NOTAM" changed from "Notice to Air Missions" to "Notice to Airmen." As such, the part-time language within the Class D and Class E surface area airspace legal descriptions should read "This Class D/E airspace area is effective during the specific dates and times established in advance by a Notice to Airmen." Additionally, the legal description of the Class E airspace area designated as an extension to a Class D or Class E airspace area within the NPRM now contains part-time language to better align with FAA regulations.
Incorporation by Reference
Class D, E2, E4, and E5 airspace designations are published in paragraphs 5000, 6002, 6004, and 6005, respectively, 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 is publicly available as listed in the ADDRESSES section of this document. FAA Order JO 7400.11J lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.
The Rule
The FAA is amending 14 CFR part 71 by modifying the Class D surface area airspace, the Class E airspace area designated as surface area, the Class E airspace areas designated as an extension to a Class D or Class E surface area, and the Class E airspace area extending upward from 700 feet above the surface of the earth at Bozeman Yellowstone International Airport, Bozeman, MT.
The radius of the Class D surface area and Class E airspace area designated as surface area is expanded to 5.1 miles to appropriately contain departures until reaching the next adjacent airspace. The southeast extension of the Class D surface area and Class E airspace area designated as surface area is removed as it is no longer needed.
In addition, the Class E airspace designated as an extension to a Class D or Class E surface area northwest of the airport is lengthened by .8 miles and widened by one mile to better contain arriving IFR aircraft on the very high frequency omnidirectional range (VOR) Runway (RWY) 12 approach while below 1,000 feet above the surface.
[top] Finally, the central radius of the Class E airspace extending upward from 700 feet above the surface is expanded to 7.2 miles to better contain IFR aircraft
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 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.
