Authority for This Rulemaking The FAAs 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 agencys 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 modifies the Class E airspace at Missoula International Airport, Missoula, MT, to ensure the safety and management of instrument flight rules IFR operations at the airport.
History The FAA published a notice of proposed rulemaking in the Federal Register 86 FR 18488; April 9, 2021 for Docket No. FAA20210208 to modify the Class E airspace at Missoula International Airport, Missoula, MT.
Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. One comment was received. The commenter suggested that the Class E5 airspace boundaries should be expanded to encompass all of the Class G airspace, extending upward from 1,200 feet above the surface, near the airport. The FAA does not agree.
Title 49 of the US Code provides the FAA with its legal authority to manage the NAS. It also provides that citizens of the United States have a public right of transit through navigable airspace.
Minimizing the volume of regulated airspace ensures the FAA is being consistent to its legislated responsibilities. Class E5 airspace is designed to contain IFR operations transitioning to or from the terminal and en route environments. Expanding the airspace boundaries for the sole purpose of reducing areas of Class G airspace would not be appropriate.
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 designation 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 7400.11E, 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 Rule This amendment to 14 CFR part 71
modifies 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 airspaces radius of the airport from 35 miles to 46
miles. The 46-mile radius will properly contain IFR aircraft transitioning to/
from the airport.
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 The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA

Impacts: Policies and Procedures, paragraph 56.5a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant the preparation of an environmental assessment.
