Amendment of Class E Airspace; Point 

Thomson, AK 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action modifies the 

airspace at Point Thomson, AK, by 

establishing Class E Airspace at Point 

Thomson Airstrip Airport, Point 

Thomson, AK. New Area Navigation 

(RNAV) Global Positioning System 

(GPS) standard instrument approach 

procedures have been established at the 

airport. This action enhances the safety 

and management of aircraft operations 

at the airport. 

DATES: Effective date, 0901 UTC, 

October 17, 2013. 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 7400.9 and 

publication of conforming amendments.

SUPPLEMENTARY INFORMATION: 

History 

On May 23, 2013, the FAA published 

in the Federal Register a notice of 

proposed rulemaking to modify 

controlled airspace at Point Thomson, 

AK (78 FR 30797). Interested parties 

were invited to participate in this 

rulemaking effort by submitting written 

comments on the proposal to the FAA. 

No comments were received. 

Class E airspace designations are 

published in paragraph 6005, of FAA 

Order 7400.9W dated August 8, 2012, 

and effective September 15, 2012, which 

is incorporated by reference in 14 CFR 

Part 71.1. The Class E airspace 

designation listed in this document will 

be published subsequently in that 

Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

modifying Class E airspace extending 

upward from 700 feet above the surface 

within an 8.9-mile radius of Point 

Thomson Airstrip Airport, Point 

Thomson, AK, to accommodate aircraft 

using new RNAV (GPS) standard 

instrument approach procedures at the 

airport. This action is necessary for the 

safety and management of IFR 

operations. 

The FAA has determined this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (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 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. The FAA’s 

authority to issue rules regarding 

aviation safety is found in Title 49 of the 

U.S. Code. Subtitle 1, Section 106 

discusses 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 modifies 

controlled airspace at Point Thomson 

Airstrip Airport, Point Thomson, AK. 

Environmental Review 

The FAA has determined that this 

action qualifies for categorical exclusion 

under the National Environmental 

Policy Act in accordance with FAA 

Order 1050.1E, ‘‘Environmental 

Impacts: Policies and Procedures,’’ 

paragraph 311a. 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.

Amendment of Class E Airspace;

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action amends Class E 

airspace at Muldrow Army Heliport, 

Lexington, OK. Changes to military 

mission requirements require 

conversion of the Class E surface area to 

a Class E transition area. This action 

enhances the safety and management of

SUPPLEMENTARY INFORMATION: 

History 

On June 3, 2013, the FAA published 

in the Federal Register a notice of 

proposed rulemaking (NPRM) to amend 

Class E airspace at Muldrow Army 

Heliport, Lexington, OK (78 FR 33017) 

Docket No. FAA–2013–0272. Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal to the 

FAA. No comments were received. Class 

E airspace designations are published in 

paragraphs 6002 and 6005, respectively, 

of FAA Order 7400.9W dated August 8, 

2012, and effective September 15, 2012, 

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. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

amending Class E airspace at Muldrow 

Army Heliport, Lexington, OK, 

removing the Class E surface area and 

creating Class E airspace extending 

upward from 700 feet above the surface 

within a 6.8-mile radius of the heliport. 

This change supports low altitude 

military helicopter operations and 

ensures that standard instrument 

approaches are conducted within 

controlled airspace for the safety and 

management of IFR operations at the 

heliport. 

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. Therefore, this regulation: (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. 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the U.S. Code. Subtitle 1, 

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 amends 

controlled airspace at Muldrow Army 

Heliport, Lexington, OK.

action qualifies for categorical exclusion 

under the National Environmental 

Policy Act in accordance with FAA 

Order 1050.1E, ‘‘Environmental
