# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Notice of proposed rulemaking (NPRM).

# SUMMARY:

This action proposes to amend Class E airspace extending upward from 700 feet above the surface for Tuscaloosa National Airport, Tuscaloosa, AL. The FAA is proposing this action as a result of an airspace review caused by the decommissioning of the CRIMSON Very High Frequency Omnidirectional Range collocated with Tactical Air Navigation (VORTAC). This action would also update name of Tuscaloosa National Airport, (formerly Tuscaloosa Municipal Airport) AL. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

# 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 amend Class E airspace for Tuscaloosa National Airport, Tuscaloosa, AL, to support IFR operations in the area.

## Comments Invited

Interested persons are invited to comment on 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.

## Availability and Summary of Documents for Incorporation by Reference

                    This document proposes to amend FAA Order 7400.11E, Airspace Designations and Reporting Points, dated July 21, 2020, and effective September 15, 2020. FAA Order 7400.11E is publicly available as listed in the                     **ADDRESSES**                     section of this document. FAA Order 7400.11E lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.                

## The Proposal

The FAA proposes an amendment to 14 CFR part 71 to amend Class E airspace extending upward from 700 feet above the surface at Tuscaloosa National Airport, Tuscaloosa, AL, as the CRIMSON VORTAC is being decommissioned. The Class E airspace extending upward from 700 feet above the surface would be amended by increasing the radius from 7.0 miles to 9.4 miles, adding an extension 4.0 miles each side of the 117° bearing from the airport extending from the 9.4-mile radius to 11.8 miles southeast of the airport and within 2.0 miles each side of the of the 041° bearing extending from the 9.4-mile radius to 11.5 miles northeast of the airport and within 4.0 miles each side of the 296° bearing extending from the 9.4-mile radius to 10.8 miles northwest of the airport and within 2.0 miles each side of the 221° bearing extending from the 9.4-mile radius to 11.8 miles southwest of the airport. This action would also update name of Tuscaloosa National Airport, (formerly Tuscaloosa Municipal Airport) AL.

Class E airspace designations are published in Paragraph 6005, of FAA Order 7400.11E, dated July 21, 2020, and effective September 15, 2020, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in the Order.

FAA Order 7400.11, Airspace Designations and Reporting Points, is published yearly and effective on September 15.

## Regulatory Notices and Analyses

The FAA has determined that this proposed 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 proposed 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.

## Environmental Review

                    This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1F, “Environmental Impacts: Policies and                           ( print page 33590)                        Procedures”, prior to any FAA final regulatory action.
