14 CFR Part 71

[Docket No. FAA-2025-5384; Airspace Docket No. 25-ANM-144]
RIN 2120-AA66


Modification of Class E Airspace; Denver International Airport, 
Denver, CO

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This action modifies the Class E airspace extending upward 
from 700 feet above the surface and removes the Class E airspace 
extending upward from 1,200 feet above the surface at Denver 
International Airport, Denver, CO. Additionally, this action makes an 
administrative modification to the airport's Class E airspace legal 
description. These actions support the safety and management of 
instrument flight rules (IFR) operations within the airspace described 
herein.

DATES: Effective date 0901 UTC, July 9, 2026. 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 E airspace to support IFR operations in 
Denver, CO.

History

    The FAA published an NPRM for Docket No. FAA-2025-5384 in the 
Federal Register (90 FR 61105; December 30, 2025), proposing to modify 
the Class E airspace at Denver International Airport, Denver, CO. 
Interested parties were invited to participate in this rulemaking 
effort by submitting written comments on the proposal to the FAA. No 
comments were received.

Incorporation by Reference

    Class E5 airspace designations are published in paragraph 6005 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 
7400.11K, dated August 4, 2025, and effective September 15, 2025. These 
amendments will be published in the next update to FAA Order JO 
7400.11. FAA Order JO 7400.11K, which lists Class A, B, C, D, and E 
airspace areas, air traffic service routes, and reporting points, is 
publicly available as listed in the ADDRESSES section of this document.

The Rule

    This rule modifies the transitional Class E airspace at Denver 
International Airport, Denver, CO, by extending the portion of the 
Class E airspace extending upward from 700 feet above the surface and 
removing the portion extending upward from 1,200 feet above the 
surface.
    The transitional Class E airspace at Denver serves Denver 
International Airport and provides containment for IFR aircraft 
operating from Denver's surrounding airports. The Class E airspace at 
Denver extends to 17.8 miles south of Centennial Airport, Denver, CO, 
to provide containment for Centennial Airport's arriving IFR aircraft 
operations below 1,500 feet above the surface. Prior to this final 
rule, the extension was not sufficient in size to fully capture the 
ZOMBZ SIX ARRIVAL (Area Navigation [RNAV]) procedure that provides 
guidance to aircraft arriving at Centennial Airport until established 
on an instrument arrival procedure (or otherwise). Accordingly, the 
Class E airspace extending upward from 700 feet above the surface at 
Denver is extended approximately four miles to the south to better 
contain the ZOMBZ SIX ARRIVAL (RNAV) procedure.
    Furthermore, the portion of Class E airspace extending upward from 
1,200 feet above the surface at Denver is removed, as the Denver Class 
E Domestic En Route Airspace provides sufficient containment and 
duplication is not necessary.
    Finally, the legal description for Denver's Class E airspace 
extending upward from at least 700 feet above the surface uses the 
Denver Very High Frequency Omnidirectional Range/Distance Measuring 
Equipment (VOR/DME) as its reference point (which is incorrectly listed 
as a VOR). The VOR Minimum Operational Network (MON) Implementation 
Program (81 FR 48694) selected the Denver VOR/DME for Phase 2 
discontinuance from the National Airspace System. As such, the Denver 
VOR/DME is no longer used to describe the airspace. A ``Point of 
Origin'' with identical geographical coordinates as

[[Page 15884]]

the Denver VOR/DME now describes the airspace in its place.

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 1050.1G, ``FAA National Environmental Policy Act 
Implementing Procedures,'' Appendix B-2.5. 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.
