# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Notice of proposed rulemaking (NPRM).

# SUMMARY:

                        This action proposes to modify the Class E airspace designated as a surface area, modify the Class E airspace extending upward from 700 feet above the surface, and remove the Class E airspace extending upward from 1,200 feet above the surface at Mammoth Lakes Airport, Mammoth Lakes, CA. Additionally, this action proposes administrative amendments to update the airport's existing Class E                               ( print page 88547)                            airspace legal descriptions. These actions would support the safety and management of instrument flight rules (IFR) operations at the airport.

# 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 the 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 modify Class E airspace to support IFR operations at Mammoth Lakes Airport, Mammoth Lakes, CA.

## Comments Invited

The FAA invites interested persons to participate in this rulemaking by submitting written comments, data, or views. Comments are specifically invited on the overall regulatory, aeronautical, economic, environmental, and energy-related aspects of the proposal. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should submit only one time if comments are filed electronically, or commenters should send only one copy of written comments if comments are filed in writing.

The FAA will file in the docket all comments it receives, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, the FAA will consider all comments it receives on or before the closing date for comments. The FAA will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. The FAA may change this proposal in light of the comments it receives.

*Privacy:*                     In accordance with 5 U.S.C. 553(c), DOT solicits comments from the public to better inform its rulemaking process. DOT posts these comments, without edit, including any personal information the commenter provides, to                     *www.regulations.gov,*                     as described in the system of records notice (DOT/ALL-14 FDMS), which can be reviewed at                     *www.dot.gov/​privacy.*

## Incorporation by Reference

                    Class E2 and E5 airspace designations are published in paragraph 6002 and 6005 respectively, of FAA Order JO 7400.11, Airspace Designations and Reporting Points, which is incorporated by reference in 14 CFR 71.1 on an annual basis. This document proposes to amend the current version of that order, FAA Order JO 7400.11H, dated August 11, 2023, and effective September 15, 2023. These updates would be published in the next update to FAA Order JO 7400.11. That order is publicly available as listed in the                     **ADDRESSES**                     section of this document.                

FAA Order JO 7400.11H 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 14 CFR part 71 that would modify the Class E airspace designated as a surface area, modify the Class E airspace extending upward from 700 feet above the surface, and remove Class E airspace extending upward from 1,200 feet above the surface at Mammoth Lakes Airport, Mammoth Lakes, CA.

The Class E surface area extension east of the airport centered on the 099° bearing should be recentered on the airport's 096° bearing instead. Additionally, the width should be reduced from 1.8 miles to 1 mile either side of the bearing, and the extension length should be reduced from 5.6 miles to 4.6 miles east of the airport. This would better contain arriving IFR operations between the surface and 1,000 feet above the surface while executing the Area Navigation (RNAV) (Global Positioning System [GPS]) Runway (RWY) 27 approach.

The existing Class E airspace extending from 700 feet above the surface should be extended eastward to include that airspace within 2.6 miles either side of the airport's 091° bearing extending from the 6.6-mile radius to 13.1 miles east of the airport. This would contain arriving IFR operations below 1,500 feet above the surface while executing the RNAV (GPS) RWY 27 approach.

                    The existing Class E airspace extending upward from 1,200 feet above                           ( print page 88548)                        the surface should be removed, as the area is already within the Coaldale Class E en route domestic airspace area.                

Finally, the FAA proposes administrative modifications to the airport's legal descriptions. The text header of both legal descriptions should be changed to match the new airport name, Mammoth Yosemite Airport. The geographic coordinates located in the text header of both legal descriptions should be updated to match the FAA's database. The text of the Class E airspace extending upward from the surface should be updated to show the new airport name and replace the outdated use of the phrases “Notice to Airmen” and “Airport/Facility Directory.” These phrases should be amended to read “Notice to Air Missions” and “Chart Supplement,” respectively, to align with the FAA's current nomenclature. The text of the Class E airspace extending upward from 700 feet above the surface should be updated to show the new airport name.

## Regulatory Notices and Analyses

The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. 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 proposed rule, when promulgated, will 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.
