reclassification process. Airspace reclassification, in effect as of

September 16, 1993, has discontinued the use of the terms ``airport

traffic area'' and ``control zones'' with operating control towers,

replacing them with the designation ``Class D airpace.'' This amendment

brings publications up to date giving continuous information to the

aviation public.

SUPPLEMENTARY INFORMATION:

History

On March 21, 1994, the FAA proposed to amend part 71 of Federal

Aviation Regulations (14 CFR part 71) by amending the Missoula,

Montana, airspace designation (59 FR 13260). Interested parties were

invited to participate in the rulemaking proceeding by submitting

written comments on the proposal. No comments were received.

During the airspace reclassification process (57 FR 38962; August

27, 1992) the language designating the Class D airspace as part time

was inadvertently omitted. This action corrects that omission. Airspace

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

use of the terms ``airspace traffic area'' and ``control zone'' with

operating control towers, and replaced them with the designation

``Class D airspace.'' The coordinates for this airspace docket are

based on North American Datum 83. Class D airspace is published in

Paragraph 5000 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 D airspace designation listed in

this document will be published subsequently in the Order.

The Rule

This amendment to part 71 of Federal Aviation Regulations amends

Class D airspace at Missoula, Montana. 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.

List of Subjects in 14 CFR Part 71
