Modification of Class D: Lawton, OK

DEPARTMENT OF TRANSPORTATION

14 CFR Part 71

[Airspace Docket No. 93-ASW-51]

Modification of Class D: Lawton, OK

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: This action modifies the Class D airspace at Lawton, OK. The

current Lawton, OK, Class D airspace encompasses both the Lawton

Municipal Airport, Lawton, OK, and Henry Post Army Airfield, Fort Sill,

OK. The local aircraft operators requested and the FAA decided to

divide the Lawton Class D airspace into two individual areas of Class D

airspace; one area covering the Lawton Municipal Airport, Lawton, OK,

and the other area covering Henry Post Army Airfield, Fort Sill, OK, as

well as re-designate the former Lawton Class E airspace as Fort Sill,

OK, Class E airspace. This action is intended to provide for more

flexibility in airspace utilization and provide control over each

individual area of airspace, particularly during times when the towers

are non-operational.

EFFECTIVE DATE: 0901 UTC, December 8, 1994.

SUPPLEMENTARY INFORMATION:

History

On November 24, 1993, a proposal to amend part 71 of the Federal

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

Lawton, OK, was published in the Federal Register (58 FR 62057). A

request was made by local aircraft operators to divide the Lawton Class

D airspace, Lawton, OK, into two separate areas of Class D airspace;

one area covering the Lawton Municipal Airport, Lawton, OK, and one

covering Henry Post Army Airfield (AAF), Fort Sill, OK. This proposed

modification would allow for more flexibility in controlling each

individual area of airspace to the extent deemed necessary,

particularly during the times when the towers are non-operational.

Interested persons were invited to participate in this rulemaking

proceeding by submitting written comments on the proposal to the FAA.

No comments objecting to the proposal were received. The current Lawton

Class D airspace has Class E extension's to the surface area. When

Lawton Municipal Airport and Henry Post AAF were designated as separate

Class D airspace areas, it became necessary to re-designate the Class E

extension's to the previous Lawton Class D airspace area as Class E

extension's to the Fort Sill Class D airspace because of their

locations. The original proposal failed to address this situation.

Therefore, this action corrects that oversight by revoking the Class E

extension's to the Lawton Class D airspace. The Class E airspace

extension's that have been revoked by this action have been re-instated

in the rulemaking action that establishes the Class D airspace for

Henry Post Army Airfield, Fort Sill OK. Except for this change, the

amendment is the same as that proposed in the notice. The FAA has

determined that this change will not increase the scope of this rule

because it is relieving, i.e. it revokes previous Class E airspace

making it less restrictive.

The coordinates for this airspace docket are based on North

American Datum 83. Class D and Class E airspace designations are

published respectively in paragraphs 5000 and 6004 of FAA Order 7400.9B

dated July 18, 1994, and effective September 16, 1994, which is

incorporated by reference in 14 CFR 71.1. The Class D and Class E

airspace designations listed in this document will be published

subsequently in the Order.

The Rule

This amendment to part 71 of the Federal Aviation Regulations (14

CFR part 71) modifies the Class D airspace at Lawton, OK, to separate

the Lawton Class D airspace into two separate Class D airspace; one

area covering the Lawton Municipal Airport, Lawton, OK, and one

covering Henry Post Army Airfield, Fort Sill, OK. This action also

revokes the Class E extension's to the previous Lawton, OK, Class D

airspace so it can be redesignated as Fort Sill, OK, Class E airspace.

The FAA has determined that this regulation only involves an

established body of technical regulations that need frequent and

routine amendments 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.
