DEPARTMENT OF TRANSPORTATION
14 CFR Part 71
[Airspace Docket No. 93-ASW-52]
Establishment of Class D and Class E Airspace: Fort Sill, OK
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This action maintains the Class D airspace that was formerly a
part of the Lawton, OK, Class D airspace, and establishes Class E
airspace at Fort Sill, OK. Henry Post Army Airfield, Fort Sill, OK, was
previously a satellite airport within the Lawton Class D airspace,
Lawton, 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. Controlled airspace from the surface is needed at Fort Sill
on a continuous basis for instrument flight rules (IFR) operations at
Henry Post Army Airfield. Therefore, during the hours the Fort Sill
airport traffic control tower (ATCT) is in operation, Class D airspace
will be in effect, and during hours the ATCT is non-operational, Class
E airspace will be in effect. This action is intended to provide for
more flexibility in airspace utilization and to 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 split the Class D airspace at
Lawton, OK. into Lawton, OK, Class D airspace and Ft. Sill, OK, Class D
airspace, and re-designate Lawton, OK, Class E airspace as Fort Sill,
OK, airspace, was published in the Federal Register (For Lawton, OK. at
58 FR 62057, for Fort Sill, OK. at 58 FR 62054). Prior to this action,
Henry Post Army Airfield, Fort Sill, OK, was a satellite airport within
the Lawton Class D airspace, Lawton, OK. 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. This proposed action would provide
for more flexibility and control of the airspace from the surface when
it is needed at Fort Sill, OK, for instrument flight rules (IFR)
operations at Henry Post AAF. This action will establish Class D
airspace during hours the airport traffic control tower (ATCT) is
operational and Class E airspace during hours the ATCT is 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 Notice of
proposed rulemaking described extensions to the Class D airspace 4-mile
radius as ``within 1.3 miles each side of the 181 deg. bearing from the
Trail NDB extending from the 4-mile radius to 6.2 miles north of the
Henry Post AAF and within 1.2 miles each side of the 003 deg. radial of
the Lawton VOR/DME extending from the 4-mile radius to 4.7 miles north
of the Henry Post AAF''. If any extension to a Class D airspace extends
beyond 2 miles, all extensions for the Class D airspace area will be
classified as Class E airspace. The airspace extensions as described in
the NPRM would have lead to an incorrect classification of the airspace
extensions as Class D airspace instead of Class E airspace. The
proposal should not have included the extensions within the Class D
description. Therefore, the narrative description of the Class D
airspace has been corrected to exclude these extensions, and a separate
Class E description has been added for this airspace. Other than these
changes, this amendment is the same as that proposed in the notice. The
FAA has determined that these changes will not increase the scope of
this rule since they are relieving in nature, i.e., re-designating
proposed Class D airspace to less restrictive Class E airspace.
The coordinate for this airspace docket are based on North American
Datum 83. Class D airspace designations are published in paragraph
5000, Class E extensions to a Class D surface area are published in
paragraph 6004, and Class E airspace designated as a surface area for
an airport are published in paragraph 6002 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) establishes separate Class D and Class E airspace for
Henry Post Army Airfield, Fort Sill, OK.
The FAA has determined that this regulation only involves an
established body of technical regulations that need frequent and
routine amendments to keep them operational current. If, 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.
