Start Preamble


Federal Aviation Administration (FAA), DOT.


Final rule.


This action will modify Class E airspace at Forsyth, MT. Controlled airspace is necessary to accommodate aircraft using Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Tillitt Field Airport. This action also corrects a typographical error in the regulatory text for the Class E airspace area. This action improves the safety and management of Instrument Flight Rules (IFR) operations at the airport.


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.

On June 7, 2011, the FAA published in the Federal Register a notice of proposed rulemaking to modify controlled airspace at Forsyth, MT (76 FR 32879). 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 7400.9U 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 airspace extending upward from 700 feet above the surface, at Tillitt Field Airport, Forsyth, MT, to accommodate IFR aircraft executing RNAV (GPS) standard instrument approach procedures at the airport. This action also corrects a typographical error in the regulatory text of the Class E airspace area by correcting `lat. 46°05′00″ N., long. 106°210′3″ W.' to `lat. 46°05′ 00″ N., long. 106°21′ 03″ W.'. This action is necessary for the safety and management of IFR operations. Except for administrative changes, and the changes listed above, this rule is the same as that proposed in the NPRM.

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 establishes additional controlled airspace at Tillitt Field Airport, Forsyth, MT.
