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 amends Class D and Class E airspace at Bowman Field Airport, 
Louisville, KY, to support IFR operations at the airport.

History

    The FAA published a final rule in the Federal Register (82 FR 
50506; November 1, 2017) for Docket No. FAA-2016-9499 amending Class D 
airspace, and Class E surface airspace at Bowman Field Airport, 
Louisville, KY.
    Subsequent to publication, the FAA discovered the Louisville 
Standiford Field Class C airspace exclusionary language was omitted 
from the Class D legal description of the airport. This rule adds the 
Class C exclusionary language into the legal descriptions, noting the 
airport name change to Louisville International Airport.
    An editorial change is made that removes the airport name from the

[[Page 45821]]

Louisville, KY, airspace designation, and the city from the airport 
name.
    Class D airspace and Class E surface airspace designations are 
published in paragraph 5000, and 6002 of FAA Order 7400.11B dated 
August 3, 2017, and effective September 15, 2017, which is incorporated 
by reference in 14 CFR part 71.1. The Class D and E airspace 
designations listed in this document will be published subsequently in 
the Order.

Availability and Summary of Documents for Incorporation by Reference

    This document amends FAA Order 7400.11B, Airspace Designations and 
Reporting Points, dated August 3, 2017, and effective September 15, 
2017. FAA Order 7400.11B is publicly available as listed in the 
ADDRESSES section of this document. FAA Order 7400.11B lists Class A, 
B, C, D, and E airspace areas, air traffic service routes, and 
reporting points.

The Rule

    This action amends Title 14 Code of Federal Regulations (14 CFR) 
part 71 by adding to the Class D and Class E surface area legal 
descriptions for Bowman Field Airport, Louisville, KY, the following 
text that reads ``excluding that portion within the Louisville 
International Airport Class C airspace area, and excluding that portion 
south of the 081[deg] bearing from Louisville International Airport, 
and also excluding that portion north of the Louisville International 
Airport Class C airspace area and west of a line drawn from lat. 
38[deg]11'28'' N long. 85[deg]42'01'' W direct thru the point where the 
030[deg] bearing from Louisville International Airport intersects the 
5-mile radius from Louisville International Airport to the point of 
intersection with the 3.9-mile radius from Bowman Field Airport.'' This 
action makes an editorial change to the Louisville, KY, airspace 
designation by removing the airport name of Bowman Field. This action 
also removes the city name (Louisville) from the airport name of Bowman 
Field Airport, to comply with FAA Order 7400.2L, Procedures for 
Handling Airspace Matters.
    Accordingly, action is take herein to add this exclusion of 
Louisville International Airport Class C airspace to the legal 
description for Bowman Field Airport, Louisville, KY, in the interest 
of flight safety. Therefore, I find that notice and public procedure 
under 5 U.S.C. 553(b) are impracticable and contrary to the public 
interest.
    To avoid confusion on the part of pilots flying in the area of 
Bowman Field Airport, Louisville, KY, the FAA finds good cause, 
pursuant to 5 U.S.C. 553(d), for making this rule effective in less 
than 30 days in order to promote the safe and efficient handling of air 
traffic in the area.

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. 
Therefore, this regulation: (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 only affects air traffic procedures and air navigation, it is 
certified that this rule, when promulgated, does not have a significant 
economic impact on a substantial number of small entities under the 
criteria of the Regulatory Flexibility Act.

Environmental Review

    The FAA has determined that this action qualifies for categorical 
exclusion under the National Environmental Policy Act in accordance 
with FAA Order 1050.1F, ``Environmental Impacts: Policies and 
Procedures,'' paragraph 5-6.5a. This airspace action is not expected to 
cause any potentially significant environmental impacts, and no 
extraordinary circumstances exist that warrant preparation of an 
environmental assessment.
