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 Class E airspace at Inyokern Airport, Inyokern, CA, 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 56845; October 13, 2021) for Docket No. FAA-2021-0805 to modify the Class E
airspace at Inyokern Airport, Inyokern, CA. Interested parties were invited to participate
in this rulemaking effort by submitting written comments on the proposal to the FAA.
The FAA received one comment in favor of the airspace changes.
Class E5 airspace designations are published in paragraph 6005 of FAA Order JO
7400.11F, dated August 10, 2021, and effective September 15, 2021, which is
incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this
document will be published subsequently in FAA Order JO 7400.11.
Availability and Summary of Documents for Incorporation by Reference

This document amends FAA Order JO 7400.11F, Airspace Designations and
Reporting Points, dated August 10, 2021, and effective September 15, 2021. FAA Order
JO 7400.11F is publicly available as listed in the ADDRESSES section of this document.
FAA Order JO 7400.11F 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 700 feet above the surface at Inyokern Airport, Inyokern, CA. This airspace
is designed to contain departing IFR aircraft until reaching 1,200 feet above the surface
and arriving IFR aircraft descending below 1,500 feet above the surface. To properly
contain arriving IFR aircraft performing a circling maneuver, the circular radius of the
airport is increased from “2 miles” to “4 miles”. To properly contain departing IFR
aircraft flying toward or over rising terrain, the airspace southwest of the airport is
widened and lengthened.
This action also implements two administrative updates to the Class E5 text
header. The airport name in the second line of the text header is amended from “Inyokern
Municipal Airport” to “Inyokern Airport”, to match the FAA database. The geographic
coordinates in the third line of the text header are amended to “lat. 35°39’31”N., long.
117°49’46”W.”, to match the FAA database.
FAA Order JO 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.
