SUPPLEMENTARY INFORMATION:

airspace. This regulation is within the 

scope of that authority as it would 

amend the Class D airspace and revoke 

the Class E airspace extending upward 

from 700 feet above the surface at Gila 

Bend AF Aux Airport, Gila Bend, AZ, to

Availability and Summary of 

Documents for Incorporation by 

Reference 

This document proposes to amend 

FAA Order 7400.11E, Airspace 

Designations and Reporting Points, 

dated July 21, 2020, and effective 

September 15, 2020. FAA Order 

7400.11E is publicly available as listed 

in the ADDRESSES section of this 

document. FAA Order 7400.11E 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 by: 

Amending the Class D airspace at Gila 

Bend AF Aux Airport, Gila Bend, AZ, 

by updating the geographic coordinates 

of the airport to coincide with the FAA’s 

aeronautical database; and replacing the 

outdated term ‘‘Airport/Facility 

Directory’’ with ‘‘Chart Supplement’’; 

And revoking the Class E airspace 

extending upward from 700 feet above 

the surface to at Gila Bend AF Aux 

airport as it is no longer required. 

This action is the result of a biennial 

review of the airspace. 

Class D and Class E airspace 

designations are published in paragraph 

5000 and 6005 of FAA Order 7400.11E, 

dated July 21, 2020, and effective 

September 15, 2020, which is 

incorporated by reference in 14 CFR 

71.1. The Class D and E airspace 

designations listed in this document 

will be published subsequently in the 

Order. 

FAA Order 7400.11, Airspace 

Designations and Reporting Points, is 

published yearly and effective on 

September 15. 

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, is non-controversial and 

unlikely to result in adverse or negative 

comments. 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 

10882 Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Proposed Rules 

routine matter that will only affect air 

traffic procedures and air navigation, it 

is certified that this rule, when 

promulgated, would 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.
