01-8826. Proposed Modification of Class E Airspace, Lewistown, MT

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

This action proposes to modify the Class E airspace at Lewistown, MT. Newly developed Area Navigation (RNAV) Standard Instrument Approach Procedure (SIAP) to Runway (RWY) 7 at the Lewistown Municipal Airport has made this proposal necessary. Additional Class E 700-feet and 1,200-feet controlled airspace, above the surface of the earth is required to contain aircraft executing the RNAV RWY 7 SIAP at Lewistown Municipal Airport. The intended effect of this proposal is to provide adequate controlled airspace for Instrument Flight Rules (IFR) operations at Lewistown Municipal Airport, Lewistown, MT.

DATES:

Comments must be received on or before May 25, 2001.

The Proposal

The FAA is considering an amendment to Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) by modifying Class E airspace at Lewistown, MT. A newly developed RNAV SIAP RWY 7 approach procedure at the Lewistown Municipal Airport, has made this proposal necessary. Additional Class E 700-feet and 1,200-feet controlled airspace, above the surface of the earth is required to contain aircraft executing the RNAV SIAP RWY 7 at Lewistown Municipal Airport. The FAA establishes Class E airspace where necessary to contain aircraft transitioning between the terminal and en route environments. The intended effect of this proposal is designed to provide for the safe and efficient use of the navigable airspace. This proposal would promote safe flight operations under IFR at the Lewistown Municipal Airport and between the terminal and en route transition stages.

The area would be depicted on aeronautical charts for pilot reference. The coordinates for this airspace docket are based on North American Datum 83. Class E airspace areas extending upward from 700 feet or more above the surface of the earth, are published in Paragraph 6005, of FAA Order 7400.9H dated September 1, 2000, and effective September 16, 2000, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document would be published subsequently in the Order.

The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore, (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 11013; 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 that 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.
