14 CFR Part 71

[Airspace Docket No. 00-ANM-27]


Modification of Class E Airspace, Lewistown, MT

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: This action revises the Class E airspace at Lewistown, MT. 
Newly developed Area Navigation (RNAV) Standard Instrument Approach 
Procedure (SIAP) at the Lewistown Municipal Airport made this action 
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 at Lewistown Municipal Airport.

EFFECTIVE DATE: 0901 UTC, November 1, 2001.

Aviation Administration, Docket No. 00-ANM-27, 1601 Lind Avenue SW.,

SUPPLEMENTARY INFORMATION:

History

    On April 10, 2001, the FAA proposed to amend Title 14 Code of 
Federal Regulations, part 71 (14 CFR part 71) by revising Class E 
airspace at Lewistown, MT, in order to accommodate new RNAV SIAPs at 
Lewistown Municipal Airport, Lewistown, MT (66 FR 18578). This 
amendment provides Class E5 airspace at Lewistown, MT, to meet current 
criteria standards associated with the SIAP. Interested parties were 
invited to participate in the rulemaking proceeding by submitting 
written comments on the proposal. A revision to the legal description 
as written in the Notice for Proposed Rule Making (NPRM) was required 
to amend a small discrepancy in the proposed action in order to make 
the airspace easier to chart, and to correct an error in the magnetic 
declination for this location. This is considered an insignificant 
modification to the airspace description as the corrections did not 
change the dimension of the proposed airspace action described in the 
NPRM.

The Rule

    This amendment to Title 14 Code of Federal Regulations, part 71 (14 
CFR part 71) revises Class E airspace at Lewistown, MT, in order to 
accommodate a new SIAP to the Lewistown Municipal Airport, Lewistown, 
MT. This amendment revises Class E5 airspace at Lewistown, MT, to meet 
current criteria standards associated with the RNAV and SIAP. The FAA 
establishes Class E airspace where necessary to contain aircraft 
transitioning between the terminal and en route environments. This rule 
is designed to provide for the safe and efficient use of the navigable 
airspace and to promote safe flight operations under Instrument Flight 
Rules (IFR) at the Lewistown Municipal Airport and between the terminal 
and en route transition stages.
    The area will 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 will be 
published subsequently in the Order.
    The FAA has determined that this 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 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 that this rule, will not have a significant economic impact 
on a substantial number of small entities under the criteria of the 
Regulatory Flexibility Act.
