14 CFR Part 71
[Docket No. FAA-2023-2423; Airspace Docket No. 23-ANM-63]
RIN 2120-AA66
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.
ADDRESSES: A copy of the Notice of Proposed Rulemaking (NPRM), all
comments received, this final rule, and all background material may be

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.
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
[[Page 15394]]
departing on the BOZEMAN SIX DEPARTURE (OBSTACLE) until reaching 1,200
feet above the surface. The southeast extension centered on the
131[deg] bearing is lengthened and realigned to the 136[deg] bearing to
better contain departing IFR aircraft on the BOBKT FIVE DEPARTURE (Area
Navigation [RNAV]) until reaching 1,200 feet above the surface and IFR
arrivals on the RNAV (Required Navigation Performance [RNP]) Z RWY 30
approach below 1,500 feet above the surface. The southeast extension
centered on the 155[deg] bearing is expanded by .7 miles, shortened by
.1 miles, and realigned to the 165[deg] bearing to better contain IFR
departures until reaching 1,200 feet above the surface and IFR arrivals
on the RNAV (RNP) Z RWY 30 approach below 1,500 feet above the surface.
The northwest extension is widened by .6 miles and shortened by 1 mile
to 4.2 miles on either side of the 316[deg] bearing, extending from the
7.2-mile radius to 14.7 miles northwest of the airport to contain the
hold-in-lieu-of procedure turn for the instrument landing system (ILS)
localizer (LOC) RWY 12 arrival procedure for IFR aircraft descending
below 1,500 feet above the surface.
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.
