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 Code of Federal Regulations Part 71 by modifying the Class D airspace at Helena Regional Airport, Helena, MT. The proposal would modify the Class D airspace extensions east and west of the airport to properly contain IFR departures to 700 feet above the surface. The airspace area would be described as follows: That airspace extending upward from the surface to and including 6,400 feet within a 4.4-mile radius of the airport, and within 2 miles each side of the 091° bearing from the airport, extending from the 4.4-mile radius to 5.2 miles east of the airport, and within 2 miles each side of 292° bearing from the airport, extending from the 4.4-mile radius to 5.8 miles west of Helena Regional Airport. This Class D airspace area is effective during the specific dates and times established in advance by a Notice to Airmen. The effective date and time will thereafter be continuously published in the Chart Supplement.

This action also proposes to modify Class E airspace, designated as a surface area, to be coincident with the new Class D dimensions. The airspace area would be described as follows: That airspace extending upward from the surface within a 4.4-mile radius of the airport, and within 2 miles each side of the 091° bearing from the airport, extending from the 4.4-mile radius to 5.2 miles east of the airport, and within 2 miles each side of 292° bearing from the airport, extending from the 4.4-mile radius to 5.8 miles west of Helena Regional Airport. This Class E airspace area is effective during the specific dates and times established in advance by a Notice to Airmen. The effective date and time will thereafter be continuously published in the Chart Supplement.

Additionally, this action proposes to establish Class E airspace, designated as an extension to a Class D or Class E surface area. The proposed area is designed to contain IFR aircraft descending below 1,000 feet above the surface. This airspace area would be described as follows: That airspace extending upward from the surface within an area bounded by a line beginning at lat. 46°34′18.57″ N, long. 111°51′30.319″ W, to lat. 46°38′5.89″ N, long. 111°51′24.53″ W, to lat. 46°37′12.53″ N, long. 111°45′24.67″ W, to lat. 46°32′22.72″ N, long. 111°46′31.44″ W, to lat. 46°33′24.13″ N, long. 111°54′20.01″ W, then counter-clockwise along the 4.4-mile radius of the airport to lat. 46°34′20.01″ N, long. 111°53′22.03″ W, then to the point of beginning, and within an area bounded by a line beginning at lat. 46°38′39.95″ N, long. 112°06′47.50″ W, to lat. 46°36′47.49″ N, long. 112°07′53.41″ W, to lat. 46°37′22.52″ N, long. 112°11′37.80″ W, to lat. 46°39′19.40″ N, long. 112°10′58.64″ W, then to the point of beginning west of Helena Regional Airport.

Further, this action proposes to modify Class E airspace extending upward from 700 feet above the surface. The action proposes to properly size the airspace to contain IFR departures to 1,200 feet above the surface and IFR arrivals descending below 1,500 feet above the surface. This airspace area would be described as follows: That airspace extending upward from 700 feet above the surface within an 8.3-mile radius of the airport, and within 1 mile each side of the 103° bearing from the airport, extending from the 8.3-mile radius to 10.7 miles east of the airport, and within 1.8 miles each side of the 281° bearing from the airport, extending from the 8.3-mile radius to 18.1 miles west of Helena Regional Airport.

This action also proposes to modify Class E airspace extending upward from 1,200 feet above the surface to properly contain IFR aircraft transitioning to/from the terminal and en route environments. This airspace area would be described as follows: That airspace extending upward from 1,200 feet above the surface within a 36-mile radius of Helena Regional Airport.

The action proposes to update the airport's geographic coordinates to match the FAA database. The coordinates should read lat. 46°36′24″ N, long. 111°59′0.0″ W. This action also proposes to remove the Helena VORTAC and all references to the VORTAC from the Class D, E2, and E5 legal descriptions. The navigational aid is not needed to define the airspace. Removal of the navigational aid allows the airspace to be defined from a single reference point which simplifies how the airspace is described. Additionally, the term “Airport/Facility Directory” in the last sentence of the Class D and Class E2 airspace legal descriptions is outdated and should be changed to “Chart Supplement”.

Class D, E2, E4, and E5 airspace designations are published in paragraphs 5000, 6002, 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 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.
