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 modify the Class E airspace at Missoula International 
Airport, Missoula, MT, to support IFR operations at the airport.

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. Persons wishing the FAA to 
acknowledge receipt of their comments on this notice must submit with 
those comments a self-addressed, stamped postcard on which the 
following statement is made: ``Comments to Docket No. FAA-2021-0208; 
Airspace Docket No. 21-ANM-5''. The postcard will be date/time stamped 
and returned to the commenter.
    All communications received before the specified closing date for 
comments will be considered before taking action on the proposed rule. 
The proposal contained in this notice may be changed in light of the 
comments received. A report summarizing each substantive public contact 
with FAA personnel concerned with this rulemaking will be filed in the 
docket.

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 is proposing an amendment to Title 14 CFR part 71 by 
modifying the Class E airspace, extending upward from 1,200 feet above 
the surface, at Missoula International Airport, Missoula, MT. This 
airspace is designed to contain IFR aircraft transitioning to/from the 
terminal and en route environments. This action proposes to increase 
the airspace's radius of the airport from 35 miles to 46 miles. The 46-
mile radius will properly contain IFR aircraft transitioning to/from 
the airport.
    Class E5 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 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 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.
