Federal Register / Vol. 76, No. 145 / Thursday, July 28, 2011 / Rules and Regulations 45179 

comments on the proposal to the FAA. 

No comments were received. 

Class D and E airspace designations 

are published in paragraph 5000, 6004 

and 6005, respectively, of FAA Order 

7400.9U dated August 18, 2010, and 

effective September 15, 2010, which is 

incorporated by reference in 14 CFR 

Part 71.1. The Class D and Class E 

airspace designations 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 D airspace, and Class E 

airspace designated as an extension to 

Class D surface area, and airspace 

extending upward from 700 feet above 

the surface, at Fort Huachuca, AZ. The 

FAA’s biennial review of the airspace 

found additional controlled airspace 

necessary for the safety and 

management of aircraft departing and 

arriving under IFR operations at Fort 

Huachuca, Sierra Vista Municipal 

Airport-Libby Army Airfield. This 

action updates the geographic 

coordinates to coincide with the FAA’s 

aeronautical database, and changes the 

airport name from Fort Huachuca, Libby 

AAF/Sierra Vista Municipal Airport, to 

Fort Huachuca, Sierra Vista Municipal 

Airport-Libby Army Airfield. 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 will only affect air 

traffic procedures and air navigation, it 

is certified this 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. 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 creates 

additional controlled airspace at Fort 

Huachuca, Sierra Vista Municipal 

Airport-Libby Army Airfield, Fort 

Huachuca, AZ.

SUPPLEMENTARY INFORMATION:

History 

On May 25, 2011, the FAA published 

in the Federal Register a notice of 

proposed rulemaking to amend Class E 

controlled airspace at Glasgow, MT (76 

FR 30300). 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 6002 and 6005, 

respectively, of FAA Order 7400.9U 

dated August 18, 2010, and effective 

September 15, 2010, which is 

incorporated by reference in 14 CFR 

part 71.1. The Class E airspace 

designations 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 surface airspace, and 

Class E airspace extending upward from 

700 feet above the surface, at Wokal 

Field/Glasgow International Airport, 

Glasgow, MT. Controlled airspace is 

necessary to accommodate IFR aircraft 

executing RNAV (GPS) standard 

instrument approach procedures at the 

airport. This action is necessary for the 

safety and management of IFR 

operations. This action also updates the 

airport name from Glasgow 

International Airport to Wokal Field/ 

Glasgow International Airport. 

The FAA has determined this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are

does not warrant preparation of a 

regulatory evaluation as the anticipated
