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 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 

amend the Class E airspace extending 

upward from 700 feet above the surface 

at Sundance Airport, Oklahoma City, 

OK, to support instrument flight rule 

operations at this airport. 

Comments Invited 

Interested parties are invited to 

participate in this proposed rulemaking 

by submitting such written data, views, 

or arguments, as they may desire. 

Comments that provide the factual basis 

supporting the views and suggestions

developing reasoned regulatory 

decisions on the proposal. Comments

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 

E airspace extending upward from 700 

feet above the surface to within a 6.5- 

mile (decreased from a 6.8-mile) radius 

of Sundance Airport, Oklahoma City, 

OK. 

These actions are the result of an 

airspace review caused by the 

decommissioning of the Sundance LOC 

which provided guidance to instrument 

procedures at this airport. 

Class E airspace designations are 

published in paragraph 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 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 

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.
