Proposed Amendment to Class D Airspace; Missoula, MT

DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 71

[Airspace Docket No. 94-ANM-12]

Proposed Amendment to Class D Airspace; Missoula, MT

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: This proposed rule would amend the Missoula, Montana, Class D

airspace from full-time back to part-time. This action is necessary to

correct an error in the airspace description that occurred during the

airspace reclassification process. Airspace reclassification, in effect

as of September 16, 1993, has discontinued the use of the term

``airport traffic area'' and, for control zones with operating control

towers, replaced it with the designation ``Class D airspace.'' This

amendment would bring publications up-to-date giving continuous

information to the aviation public.

DATES: Comments must be received on or before April 30, 1994.

ADDRESSES: Send comments on the proposal in triplicate to: Manager,

System Management Branch, ANM-530, Federal Aviation Administration,

Docket No. 94-ANM-12, 1601 Lind Avenue SW., Renton, Washington 98055-

4056.

The official docket may be examined at the same address.

An informal docket may also be examined during normal business

hours at the address listed above.

The Proposal

The FAA is considering an amendment to part 71 of the Federal

Aviation Regulations (14 CFR part 71) to amend Class D airspace at

Missoula, Montana. During the airspace reclassification process the

language designating the Class D airspace as part-time was

inadvertently omitted. This action would correct that error. Airspace

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

the use of the term ``airport traffic area'' and, for control zones

with operating control towers, replaced it 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 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 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, when promulgated, will not have a significant

economic impact on a substantial number of small entities under the

criteria of the Regulatory Flexibility Act.
