[Airspace Docket No. 97-ASW-11]
RIN 2120-AA66


Revision of the Legal Description of the Dallas/Fort Worth Class 
B Airspace Area, TX

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: This action revises the legal description of the Dallas/Fort 
Worth (DFW) Class B airspace area by changing its point of origin from 
the DFW Very High Frequency Omnidirectional Range/Tactical Air 
Navigation (VORTAC) to the VORTAC's present geographical coordinates. 
The FAA is taking this action due to the planned relocation of the DFW 
VORTAC \3/4\ nautical miles (NM) west of its present location. The 
intent of this action is to facilitate the relocation of the DFW VORTAC 
without changing the actual dimensions, configuration, or operating 
requirements of the DFW Class B airspace area.

EFFECTIVE DATE: 0901 UTC, September 11, 1997.

SUPPLEMENTARY INFORMATION:

Background

    On September 11, 1996, the FAA published in the Federal Register a 
final rule to modify the DFW Class B airspace area (61 FR 47815). 
Specifically, the rule raised the upper limit of the DFW Class B 
airspace area from 10,000 feet mean sea level (MSL) to 11,000 feet MSL 
in some areas, reconfigured the northern and southern sections, and 
redefined several existing subareas.
    The coordinates for this airspace docket are based on North 
American Datum 83. Class B airspace areas are published in paragraph 
3000 of FAA Order 7400.9D, dated September 4, 1996, and effective 
September 16, 1996, which is incorporated by reference in 14 CFR 71.1. 
The Class B airspace area listed in this document will be published 
subsequently in the Order.

The Rule

    Due to construction on DFW airport property occurring in close 
proximity to the DFW VORTAC, the FAA will relocate the VORTAC 
approximately \3/4\ NM to the west, effective October 10, 1997. Since 
the current legal description of the DFW Class B airspace area, as 
published in the September 11, 1996, final rule, is based on radials 
and distances from the DFW VORTAC, the relocation will necessitate a 
change to the legal description of the Class B airspace area. 
Accordingly, this action changes the point of reference from the DFW 
VORTAC to the VORTAC's present geographical coordinates. This action 
will allow for the future relocation of the DFW VORTAC without altering 
the vertical or lateral limits of the existing DFW Class B airspace 
area.
    Since this action merely involves a change in the legal description 
of the DFW Class B airspace area, and does not involve a change in the 
dimensions or operating requirements of that airspace, notice and 
public procedure under 5 U.S.C. 553(b) are unnecessary.
    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. 
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.
