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

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 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.
