Modification of Class D and Class E 

Airspace; Revocation of Class E 

Airspace; Buckley Space Force Base, 

Aurora, CO 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action modifies the Class 

D airspace and Class E airspace 

designated as a surface area and revokes 

the Class E airspace designated as an 

extension to the Class D or Class E 

surface area at Buckley Space Force 

Base, Aurora, CO. Additionally, this 

action modifies the administrative 

portions of the airport’s legal 

descriptions to match the FAA’s 

database. These actions will support the 

safety and management of instrument 

flight rules (IFR) and visual flight rules 

(VFR) operations at the airport. 

DATES: Effective date 0901 UTC, 

February 20, 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 airspace and Class E airspace 

designated as a surface area and revokes 

Class E airspace designated as an 

extension to the Class D or Class E 

surface area to support IFR and VFR 

operations at Buckley Space Force Base, 

Aurora, CO. 

History 

The FAA published an NPRM for 

Docket No. FAA–2024–1857 in the 

Federal Register (89 FR 73022; 

September 09, 2024), proposing to 

amend the Class D airspace and Class E 

airspace designated as a surface area 

and revoke the Class E airspace 

designated as an extension to the Class 

D or Class E surface area Buckley Space 

Force Base, Aurora, CO. Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal to the 

FAA. Two comments were received in 

favor of the proposal. 

Incorporation by Reference 

Class D, E2, and E4 airspace 

designations are published in 

paragraphs 5000, 6002, and 6004, 

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. FAA 

Order JO 7400.11J is publicly available 

as listed in the ADDRESSES section of this 

document. These amendments will be 

published in the next update to FAA 

Order JO 7400.11. 

FAA Order JO 7400.11J lists Class A, 

B, C, D, and E airspace areas, air traffic 

service routes, and reporting points. 

The Rule 

This action amends 14 CFR part 71 by 

modifying the Class D airspace and 

Class E airspace designated as a surface 

area and revoking the Class E airspace

104406 Federal Register / Vol. 89, No. 246 / Monday, December 23, 2024 / Rules and Regulations 

designated as an extension to the Class 

D or Class E surface area at Buckley 

Space Force Base, CO. 

The lateral boundaries of the airport’s 

Class D and Class E surface areas are 

insufficiently sized and expanded to the 

southeast to better contain IFR arrivals 

when less than 1,000 feet above the 

surface and departing IFR aircraft until 

reaching the next adjacent airspace. 

Additionally, an approximately 0.30 

nautical mile gap between Class E and 

Class G airspaces is closed by merging 

the Buckley Space Force Base and 

Centennial Airport surface areas. As 

such, the Buckley Space Force Base 

Class D and Class E surface areas are 

modified to be within a 4.4-mile radius 

of the airport, within 2 miles northeast 

and 4 miles southwest of the airport’s 

151° bearing extending to 7.1 miles 

southeast, and within 4 miles south and 

4.4 miles north of the airport’s 270° 

bearing extending to 4.7 miles west, 

excluding that airspace within the 

Denver International Airport Class B 

and Centennial Airport Class D airspace 

areas. 

Buckley Space Force Base’s Class E 

airspace designated as an extension to 

the Class D or Class E surface area is 

revoked. The Class E extension is no 

longer required due to the expansion of 

the airport’s surface area airspace. 

Finally, the administrative portions of 

the airport’s legal descriptions are 

modified to match the FAA’s database. 

The airport’s name on line two of both 

legal descriptions is changed to read 

‘‘Buckley Space Force Base, CO.’’ 

Additionally, line four of both surface 

area legal descriptions now include 

‘‘Denver International Airport, CO’’ and 

‘‘Centennial Airport, CO’’ as references, 

as they are used to define the airport’s 

surface areas. 

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.
