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 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. FAA–2021–0208 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 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. 

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 

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 the preparation of an 

environmental assessment.

and 4.3 miles east of the 179° bearing 

extending from the Class D 4.4-mile radius to
