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

[[Page 18579]]

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.
