14 CFR Part 71

[Docket No. FAA-2012-0538; Airspace Docket No. 12-ANM-8]


Amendment of Class E Airspace; Lewistown, MT

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

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

DATES: Effective date, 0901 UTC, November 15, 2012. 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 June 27, 2012, the FAA published in the Federal Register a 
Notice of Proposed Rulemaking (NPRM) to modify controlled airspace at 
Lewistown, MT (77 FR 38226). 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 7400.9V dated August 9, 2011, and 
effective September 15, 2011, 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 Lewistown 
Municipal Airport, Lewistown, MT, 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.
    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 modifies 
controlled airspace at Lewistown Municipal Airport, Lewistown, MT.

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.
