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 Great Falls International Airport, Great Falls, MT, to ensure the safety and management of IFR operations at the airport.
History The FAA published a notice of proposed rulemaking in the Federal Register 86 FR 3891, January 15, 2021
for Docket No. FAA20201126 to modify the Class E airspace at Great Falls International Airport, Great Falls, MT. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received.
Subsequent to publication of the NPRM, the FAA identified an error in the description for the airspace extending upward from 700 feet above the surface. In the NPRM a portion of this airspace was described as within 8 miles south and 4 miles north of the 222 from the airport, extending from 2.6 miles southwest of the airport to 18.7 miles southwest of the airport.
The Final Rule corrects this description to read within 8 miles south and 4
miles north of the 225 bearing from the airport, extending from 2.6 miles southwest of the airport to 18.7 miles southwest of the airport.
Class D, E4, and E5 airspace designations are published in paragraph 5000, 6004, and 6005, respectively, 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 D and 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, designated as an extension to a Class D
or Class E surface area, at Great Falls International Airport. This action reduces the size of the area to properly contain IFR aircraft descending below 1,000 feet above the surface.
This action also modifies the Class E
airspace extending upward from 700
feet above the surface. This action significantly reduces the size of this area to properly contain IFR departures to 1,200 feet above the surface and IFR
arrivals descending below 1,500 feet above the surface.
Additionally, this action modifies the Class E airspace extending upward from 1,200 feet above the surface. This action reduces the size of this area to properly contain IFR aircraft transitioning to/
from the terminal and en route environments.
This action also removes the Great Falls VORTAC from the Class E4 and Class E5 text headers and airspace descriptions. The Navigational Aid NAVAID is not needed to describe the airspace areas. Removal of the NAVAID
allows the airspace to be described from a single point, which simplifies the airspaces descriptions.
Further, this action removes Malmstrom AFB from the Class E5 text header and airspace description.
Reference to Malmstrom AFB is not needed to describe the airspace area.
Removal of Malmstrom AFB allows the airspace to be described from a single point, which simplifies the airspaces description.
Lastly, this action implements several administrative amendments to the airspaces legal descriptions. The first line of the Class D and Class E4 text headers is amended to remove the airport name. The airports geographic coordinates in the Class D, Class E4, and Class E5 text header are updated to lat.
