14 CFR Part 71

[Docket No. FAA-2011-0362; Airspace Docket No. 11-ANM-7]

Modification of Class E Airspace; Glasgow, MT

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This action modifies Class E airspace at Wokal Field/Glasgow 
International Airport, Glasgow, MT. Controlled airspace is necessary to 
accommodate aircraft using Area Navigation (RNAV) Global Positioning 
System (GPS) standard instrument approach procedures at the airport. 
This improves the safety and management of Instrument Flight Rules 
(IFR) operations at the airport. This action also updates the airport 
name.

DATES: Effective date, 0901 UTC, October 20, 2011. 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 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. 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 Wokal Field/Glasgow International 
Airport, Glasgow, MT.
