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 airspace and revoke 

Class E airspace designated as an 

extension to a Class D or Class E surface 

area to support IFR and VFR operations 

at Centennial Airport, Denver, CO. 

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 

time if comments are filed 

electronically, or commenters should 

send only one copy of written 

comments if comments are filed in 

writing. 

The FAA will file in the docket all 

comments it receives, as well as a report 


ddrumheller on DSK120RN23PROD with PROPOSALS1
Federal Register / Vol. 89, No. 174 / Monday, September 9, 2024 / Proposed Rules 73021 

summarizing each substantive public 

contact with FAA personnel concerning 

this proposed rulemaking. Before acting 

on this proposal, the FAA will consider 

all comments it receives on or before the 

closing date for comments. The FAA 

will consider comments filed after the 

comment period has closed if it is 

possible to do so without incurring 

expense or delay. The FAA may change 

this proposal in light of the comments 

it receives. 

Privacy: In accordance with 5 U.S.C. 

553(c), DOT solicits comments from the 

public to better inform its rulemaking 

process. DOT posts these comments, 

without edit, including any personal 

information the commenter provides, to 

www.regulations.gov, as described in 

the system of records notice (DOT/ALL– 

14 FDMS), which can be reviewed at

You may review the public docket 

containing the proposal, any comments 

received and any final disposition in 

person in the Dockets Operations office 

(see ADDRESSES section for address,

business hours at the office at the 

Northwest Mountain Regional Office of 

the Federal Aviation Administration,

Service Center, Operations Support 

Group, 2200 S 216th Street, Des Moines, 

WA 98198. 

Incorporation by Reference 

Class D airspace and Class E4 airspace 

designations are published in paragraph 

5000 and 6004 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 7400.11H, dated 

August 11, 2023, and effective 

September 15, 2023. 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 7400.11H lists Class A, 

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

service routes, and reporting points. 

Background 

Centennial Airport’s airspaces are 

concurrently being evaluated with the 

Class D and Class E airspaces associated 

with Buckley Space Force Base (BKF), 

Aurora, CO. APA and BKF Category D 

aircraft’s instrument approach 

procedures (IAP)-approved radius for 

conducting a circling maneuver 

overlaps in Class E airspace. APA’s 

Category D aircraft conducting a circling 

maneuver to Runway 17 Left flight 

pattern extends beyond the airport’s 

Class D airspace lateral boundary. 

Additionally, APA and BKF Class D 

airspaces are separated by less than .30 

nautical miles (NM). This narrow 

airspace area is comprised of controlled 

and uncontrolled airspaces; this creates 

an unfavorable passage as VFR aircraft 

navigate between the two airports’ 

surface areas. 

The Proposal 

The FAA is proposing an amendment 

to 14 CFR part 71 to modify the Class 

D airspace and revoke the Class E 

airspace designated as an extension to a 

Class D or Class E surface area at 

Centennial Airport, Denver, CO, to 

support IFR and VFR operations at the 

airport. 

The airport’s Class D airspace lateral 

boundary should be modified to extend 

3.9 NM northwest and 4.6 NM southeast 

from the airport’s 038° bearing 

extending 4.6 NM northeast. This 

expansion along with the proposed 

airspace modification associated with 

BKF would merge both airport’s surface 

areas, which would require transiting 

VFR aircraft to utilize 500 feet of Class 

E airspace area between the tops of BKF 

Class D airspace and the floor of the 

Denver Class B airspace. Additionally, 

the Class D should be expanded from a 

4.4 NM radius to a 6.4 NM radius 

between the airports 083° bearing 

clockwise to the 201° bearing. Due to 

rising terrain, this modification would 

better contain instrument departures as 

the aircraft reaches 700 feet above the 

surface of the earth. The Class D should 

also extend from a 4.4 NM radius to a 

4.9 NM radius between the airport’s 

201° bearing clockwise to the 347° 

bearing to better contain aircraft 

conducting a circling maneuver at the 

airport. 

The Class E airspace designated as an 

extension to a Class D or Class E surface 

area should be revoked. The airport’s 

proposed Class D new lateral dimension 

would contain all obligated IFR 

requirements that would be necessary in 

the continuation of the airport’s Class E 

airspace. 

Lastly, the FAA is proposing a few 

administrative amendments to the 

airport’s legal description. The city’s 

name should be amended from 

Englewood to Denver. The airport’s 

geographic coordinates should be 

amended to 39°34′12′′ N, long 

104°50′57′′ W. The part-time language 

should be removed as the facility 

operates 24 hours daily. 

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.
