Proposed Revocation of Class D and E Airspace; Fort Sill; and 
Amendment of Class D and E Airspace; Lawton, OK

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: This action proposes to remove Class D airspace, Class E 
airspace designated as a surface area, and Class E airspace designated 
as an extension to a Class D and Class E airspace at Henry Post Army 
Air Field (AAF), Fort Sill, OK; amend Class D airspace and Class E 
airspace designated as a surface area at Lawton-Fort Sill Regional 
Airport, Lawton, OK; and amend Class E airspace extending upward from 
700 feet above the surface at Lawton-Fort Sill Regional Airport and 
Henry Post AAF. The FAA is proposing this action due to the closure of 
the air traffic control tower (ATCT) at Henry Post AAF. The name of 
Lawton-Fort Sill Regional Airport and the geographic coordinates of 
Henry Post AAF would also be updated to coincide with the FAA's 
aeronautical database, and the outdated term ``Airport/Facility 
Directory'' would be replaced with the term ``Chart Supplement.''

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is 
found in Title 49 of the United States Code. Subtitle I, Section 106 
describes the authority of the FAA Administrator. Subtitle VII, 
Aviation Programs, describes in more detail the scope of the agency's 
authority. This rulemaking is promulgated under the authority described 
in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, 
the FAA is charged with prescribing regulations to assign the use of 
airspace necessary to ensure the safety of aircraft and the efficient 
use of airspace. This regulation is within the scope of that authority 
as it would remove Class D airspace, Class E airspace designated as a 
surface area,

[[Page 22890]]

and Class E airspace designated as an extension to a Class D and Class 
E airspace at Henry Post AAF, Fort Sill, OK; amend Class D airspace and 
Class E airspace designated as a surface area at Lawton-Fort Sill 
Regional Airport, Lawton, OK; and amend Class E airspace extending 
upward from 700 feet above the surface at Lawton-Fort Sill Regional 
Airport and Henry Post AAF to support instrument flight rule operations 
at these airports.

Comments Invited

    Interested parties are invited to participate in this proposed 
rulemaking by submitting such written data, views, or arguments, as 
they may desire. Comments that provide the factual basis supporting the 
views and suggestions presented are particularly helpful in developing 
reasoned regulatory decisions on the proposal. Comments are 
specifically invited on the overall regulatory, aeronautical, economic, 
environmental, and energy-related aspects of the proposal. 
Communications should identify both docket numbers and be submitted in 
triplicate to the address listed above. Commenters wishing the FAA to

The Proposal

    The FAA is proposing an amendment to Title 14, Code of Federal 
Regulations (14 CFR) part 71 by:
    Removing Class D airspace at Henry Post AAF, Fort Sill, OK;
    Amending Class D airspace at Lawton-Fort Sill Regional Airport 
(formerly Lawton Municipal Airport), Lawton, OK, by adding an extension 
1.1 miles each side of the 167[deg] radial of the Lawton VOR/DME 
extending from the 4.3-mile radius to 5.3 miles south of the airport; 
amending the exclusionary language from ``that airspace north of a line 
between lat. 34[deg]36'18'' N, long. 98[deg]20'33'' W and lat. 
34[deg]37'16'' N, long. 98[deg]28'29'' W; to ``that airspace within a 
2.0-mile radius of Henry Post AAF''; updating the name of the airport 
to coincide with the FAA's aeronautical database; and replacing the 
outdated term ``Airport/Facility Directory'' with ``Chart Supplement'';
    Removing Class E airspace designated as a surface area at Henry 
Post AAF;
    Amending Class E airspace designated as a surface area at Lawton-
Fort Sill Regional Airport by adding an extension 1.1 miles each side 
of the 167[deg] radial of the Lawton VOR/DME extending from the 4.3-
mile radius to 5.3 miles south of the airport; removing that area 
within a 4-mile radius of Henry Post AAF from the airspace legal 
description; amending the exclusionary language from ``within 
Restricted Areas R5601A and R-5601B when these restricted areas are 
activated'' to ``that airspace within a 2.0-mile radius of Henry Post 
AAF''; updating the name of the Lawton-Fort Sill Airport (formerly 
Lawton Municipal Airport), and the geographic coordinates of Henry Post 
AAF to coincide with the FAA's aeronautical database; removing the city 
name associated with Henry Post AAF to comply with FAA Order 7400.2L, 
Procedures for Handling Airspace Matters; and replacing the outdated 
term ``Airport/Facility Directory'' with ``Chart Supplement'';
    Removing Class E airspace designated as an extension of Class D and 
Class E airspace at Henry Post AAF; and
    Amending Class E airspace extending upward from 700 feet above the 
surface at Lawton-Fort Sill Regional Airport and Henry Post AAF by 
amending the extension to the south of Lawton-Fort Sill Regional 
Airport from the 167[deg] (previously 178[deg]) radial from the Lawton 
VOR/DME extending from the 6.8-mile radius to 13.1 (decreased from 
20.6) miles south of the Lawton-Fort Sill Regional Airport; removing 
the extension from the 358[deg] radial from Lawton VOR/DME; removing 
the extension to the north of Henry Post AAF referencing the 003[deg] 
radial from the Lawton VOR/DME; adding an extension 4.0 miles each side 
of the 360[deg] bearing from the Henry Post AAF from the 6.5-mile 
radius of Henry Post AAF to 10.9 miles north of Henry Post AAF; 
amending the exclusionary language pertaining to restricted areas from 
``R-5601A and R-5601B when these restricted areas are activated'' to 
``R-5601A, R-5601B and R-5601H when active''; removing the exclusionary 
language ``and excluding that airspace within the Wichita Falls, TX, 
Class E airspace area'' from the airspace legal description; and 
updating the name of Lawton-Fort Sill Regional (formerly Lawton 
Municipal Airport) and the geographic coordinates of Henry Post AAF to 
coincide with the FAA's aeronautical database.
    This action is being proposed due to the closure of the ATCT at 
Henry Post AAF and to remove the associated airspace.
    Class D and E airspace designations are published in paragraph 
5000, 6002, 6004, and 6005, respectively, of FAA Order 7400.11B, dated 
August 3, 2017, and effective September 15, 2017, which is incorporated 
by reference in 14 CFR 71.1. The Class D and E airspace designations 
listed in this document will be published subsequently in the Order.

Regulatory Notices and Analyses

    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, is 
non-controversial and unlikely to result in adverse or negative 
comments. It, therefore: (1) Is not a ``significant regulatory action'' 
under Executive Order 12866; (2) is not a ``significant rule'' under 
DOT

[[Page 22891]]

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, would not have a 
significant economic impact on a substantial number of small entities 
under the criteria of the Regulatory Flexibility Act.

Environmental Review

    This proposal will be subject to an environmental analysis in 
accordance with FAA Order 1050.1F, ``Environmental Impacts: Policies 
and Procedures'' prior to any FAA final regulatory action.
