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 would 

modify Class D and Class E airspace to 

support VFR and IFR operations at 

Bozeman Yellowstone International 

Airport, Bozeman, MT. 

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

WA 98198. 

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 proposes to 

amend the current version of that order, 

FAA Order JO 7400.11J, dated July 31, 

2024 and effective September 15, 2024. 

These updates would be published in 

the next update to FAA Order JO 

7400.11. That order 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 Proposal 

The FAA is proposing an amendment 

to 14 CFR part 71 that would modify 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 should be 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 designated as 

surface area should be eliminated 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 should be 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 should be 

expanded to 7.2 miles to better contain 

IFR aircraft departing on the BOZEMAN 

SIX DEPARTURE (OBSTACLE) until 

reaching 1,200 feet above the surface. 

The southeast extension centered on the 

131° bearing should be lengthened and 

realigned to the 136° 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° bearing should be 

expanded by .7 miles, shortened by .1 

miles, and realigned to the 165° 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 should be widened .6 miles 

and shortened 1 mile to 4.2 miles on 

either side of the 316° bearing, 

extending from the 7.2-mile radius to 

14.7 miles northwest of the airport to 

contain the hold-in-lieu of pattern 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 

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 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 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 1050.1F, 

‘‘Environmental Impacts: Policies and 

Procedures’’ prior to any FAA final 

regulatory action.
