AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

This action proposes to amend Class E4 airspace areas extending upward from the surface and Class E5 airspace areas extending upward from 700 and 1,200 feet above the surface of the earth at Missoula International Airport, Missoula, MT. This action also proposes to remove the Missoula VORTAC from the legal description as it is not needed to describe the airspace and using the airport as the single reference point enhances the simplicity of describing the airspace. Additionally, this action also proposes to make administrative corrections to the airport's Class D and Class E2 legal descriptions. This action would ensure the safety and management of IFR operations at the airport.

DATES:

Comments must be received on or before November 25, 2019.

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 amend the Class E airspace at Missoula International Airport, Missoula, MT to support instrument flight rules (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-2019-0761; Airspace Docket No. 19-ANM-18”. 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 7400.11D, Airspace Designations and Reporting Points, dated August 8, 2019, and effective September 15, 2019. FAA Order 7400.11D is publicly available as listed in the ADDRESSES section of this document. FAA Order 7400.11D 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 (14 CFR) Part 71 by amending Class E4 airspace at Missoula International Airport extending upward from the surface within 1.2 miles each side of the 310° bearing extending from the 4.4-mile radius to 10.8 miles northwest of the airport, and within 1.3 miles each side of the 295° bearing extending from the 4.4-mile radius to 5.6 miles northwest of the airport, and within 0.7 miles each side of the 142° bearing extending from the 4.4-mile radius to 5.6 miles southeast of the airport, and within 1.5 miles each side of the 171° bearing extending from the 4.4-mile radius to 10.6 miles south of the Missoula International Airport. This airspace is designed to contain IFR aircraft descending below 1,000 feet above the surface.

This action also proposes to amend Class E5 airspace extending upward from 700 feet above the surface within 3.5 miles each side of the 311° bearing extending from the 4.4-mile radius to 22.3 miles northwest of the airport, and 1.6 miles west and 4.3 miles east of the 179° bearing extending from the 4.4-mile radius to 15.2 miles south of the Missoula International Airport. This airspace is designed to contain IFR aircraft descending below 1,500 feet above the surface. Further, this action proposes to amend Class E5 airspace extending upward from 1,200 feet above the surface within a 35-mile radius of the Missoula International Airport. This action also proposes an administrative update to remove the Missoula VORTAC from the legal description, this will allow the airspace to be described from a single point, enhancing the simplicity of airspace description.

Further, this action proposes to remove the Missoula VORTAC from the Class E5 legal description. The VORTAC is not needed to define the airspace and removing reference to it allows for a simpler description of the airspace from the airport.

Lastly, this action proposes an administrative update to the Class D and Class E2 legal descriptions to replace Airport/Facilities Directory with Chart Supplement.

Class D, E2, E4 and E5 airspace designations are published in paragraphs 5000, 6002, 6004 and 6005, respectively, of FAA Order 7400.11D, dated August 8, 2019, and effective September 15, 2019, which is incorporated by reference in 14 CFR 71.1. The Class D and 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.
