14 CFR Part 71

[Airspace Docket No. 97-ANM-08]


Establishment of Class E Airspace; Twin Falls, ID

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: This action establishes the Twin Falls, ID, Class E airspace. 
The recent commissioning of the Twin Falls Automated Surface 
Observation System (ASOS) qualifies the Joslin Field-Magic Valley 
Regional Airport for a Class E surface area. The intended effect of 
this action is to provide the controlled airspace necessary, when the 
control tower is closed and Class D airspace is not active, to enable 
the FAA to provide Instrument Flight Rules (IFR) air traffic control 
services and separation to IFR aircraft.

EFFECTIVE DATE: 0901 UTC, January 1, 1998.

Aviation Administration, Docket No. 97-ANM-08, 1601 Lind Avenue S.W.,

SUPPLEMENTARY INFORMATION:

History

    On June 17, 1997, the FAA proposed to amend Title 14, Code of 
Federal Regulations part 71 (14 CFR part 71) by establishing the Class 
E airspace area at Twin Falls, ID, (62 FR 32704). The recent 
commissioning of the Twin Falls ASOS qualifies the Joslin Field-Magic 
Valley Regional Airport for a Class E surface area. In the notice of 
proposed rulemaking action, the airport name was inadvertently listed 
as Twin Falls-Sun Valley Regional, Joslin Field. The correct name is 
Joslin Field-Magic Valley Regional Airport. Additionally, an error was 
discovered in the airport coordinates. These errors are corrected 
herein.
    Interested parties were invited to participate in the rulemaking 
proceeding by submitting written comments on the proposal. No comments 
were received. The coordinates for this airspace docket are based on 
North American Datum 83. Class E airspace areas designated as a surface 
area for an airport are published in Paragraph 6002 of FAA Order 
7400.9E, dated September 10, 1997, and effective September 16, 1997, 
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 Rule

    This amendment to 14 CFR part 71 establishes Class E airspace 
within a 4.3 nautical mile radius of the Joslin Field-Magic Valley 
Regional Airport, Twin Falls, ID. Where communications and weather 
reporting criteria are met, the FAA establishes Class E airspace 
extending upward from the surface to the base of the overlying 
controlled airspace to contain terminal instrument operations if such 
action is justified and/or in the public interest. The recent 
installation and commissioning of the Twin Falls ASOS qualifies the 
Joslin Field-Magic Valley Regional Airport for a Class E surface area. 
The intended effect of this action is to provide the controlled 
airspace necessary, when the control tower is closed and Class D 
airspace is not active, to enable the FAA to provide IFR air traffic 
control services and separation to IFR aircraft at the Joslin Field-
Magic Valley Regional Airport. The area would be depicted on 
aeronautical charts for pilot reference.
    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 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.
