Amendment to Class E Airspace; Twin Falls, ID

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: This action amends the Class E airspace at Twin Falls, ID.

Establishment of a new instrument approach procedure requires

additional controlled airspace for the procedure. Airspace

reclassification, in effect as of September 16, 1993, has discontinued

use of the term ``transition area'' replacing it with the designation

``Class E airspace. The Class E airspace will be depicted on

aeronautical charts for pilot reference when the new approach

procedures become effective.

EFFECTIVE DATE: 0901 u.t.c. June 23, 1994.

SUPPLEMENTARY INFORMATION:

History

On February 18, 1994, the FAA proposed to amend part 71 of the

Federal Aviation Regulations (14 CFR part 71) to amend the Class E

airspace for the Twin Falls-Sun Valley Regional, Joslin Field Airport,

ID (59 FR 8148). Interested parties were invited to participate in the

rulemaking process by submitting such written data, views, or arguments

as they desired. No comments were received.

Airspace reclassification, in effect as of September 16, 1993, has

discontinued use of the term ``transition area,'' and certain airspace

extending upward from 700 feet above ground level is now designated

Class E airspace. Class E airspace designations for airspace extending

upward from 700 feet above ground level are published in Paragraph 6005

of FAA Order 7400.9A dated June 17, 1993, and effective September 16,

1993, which is incorporated by reference in 14 CFR 71.1 (58 FR 36298;

July 6, 1993). The Class E airspace designations listed in this

document will be published subsequently in the Order. The coordinates

in this final rule are in North America Datum 83.

The Rule

This amendment to part 71 of the Federal Aviation Regulations

amends Class E airspace at Twin Falls, Idaho. It will provide

controlled airspace for a new instrument approach procedure at the

airport. Amendment of the Class E airspace will result in greater

safety and efficiency at, and in the vicinity of, the airport. 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.
