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 and establish Class E airspace to support
IFR operations at Cortez Municipal Airport, Cortez, CO.
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
[[Page 4685]]
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 <a href="http://www.regulations.gov">www.regulations.gov</a>, as described in the system
of records notice (DOT/ALL-14 FDMS), which can be reviewed at
<a href="http://www.dot.gov/privacy">www.dot.gov/privacy</a>.

Service Center, Operations Support Group, 2200 S. 216th Street, Des
Moines, WA 98198.
Incorporation by Reference
Class E2, E4, and E5 airspace designations are published in
paragraphs 6002, 6004, 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 7400.11J, dated
July 31, 2024 and effective September 15, 2024. 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 7400.11J 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
establish Class E airspace designated as an extension to a Class E
surface area at Cortez Municipal Airport, Cortez, CO.
The radius of the Class E airspace designated as a surface area
should be widened by a half mile to better contain arriving IFR
aircraft when less than 1,000 feet above the surface when conducting
circling maneuvers or when executing the area navigation (RNAV) (Global
Positioning System [GPS]) Runway (RWY) 3 approach, and aircraft
conducting the missed approach portions of the Very High Frequency
Omnidirectional Range (VOR) RWY 3, RNAV (GPS) Y RWY 21, and RNAV (GPS)
Z RWY 21 approaches until reaching the next adjacent airspace.
Furthermore, the Class E surface area should be extended .8 miles to
the northeast to laterally contain IFR departure operations while
between the surface and the base of adjacent controlled airspace when
executing the LEDVE RWY 3 or CORTEZ TWO RWY 3 departure procedures.
Moreover, the Class E surface area should be extended 2.4 miles to the
southwest to laterally contain IFR departure operations while between
the surface and the base of adjacent controlled airspace when executing
the LEDVE RWY 21 or CORTEZ TWO RWY 21 departure procedures. Finally,
the northern leg of the Class E surface area no longer serves the
purpose of containment and should be removed.
An extension to the Class E surface area measuring approximately 8
x 8 miles should be established to the northeast, as the Class E
surface area does not fully contain arriving IFR aircraft when less
than 1,000 feet above the surface when executing the RNAV (GPS) Y RWY
21 or RNAV (GPS) Z RWY 21 approaches. An extension to the Class E
surface area would contain these operations more appropriately without
imposing a 2-way radio communication requirement.
The central radius of the Class E airspace extending upward from
700 feet above the surface should be reduced from 7 miles to 6.1 miles,
as there are portions of the airspace to the southeast and west that do
not provide procedural containment. Secondly, the northern extension of
the Class E airspace extending upward from 700 feet above the surface
should be widened by 6 miles and re-aligned to the northeast, which
would better contain arriving IFR operations below 1,500 feet above the
surface when executing the RNAV (GPS) Y RWY 21 or RNAV (GPS) Z RWY 21
approaches. The Class E airspace extending upward from 700 feet above
the surface should be extended to the southwest to contain aircraft
more appropriately until reaching 1,200 feet above the surface when
executing the CORTEZ TWO RWY 21 or LEDVE ONE RWY 21 departure
procedures, or the missed approach portion of the RNAV (GPS) Z RWY 21
approach until reaching 1,200 feet above the surface. Lastly, the Class
E airspace extending upward from 700 feet above the surface should be
extended 1.8 miles to the north-northwest of the airport to better
contain aircraft executing the missed approach portion of the RNAV
(GPS) Y RWY 21 approach until reaching 1,200 feet above the surface.
Finally, the FAA proposes administrative modifications to the
airport's legal descriptions. The airport's name on line two of the
legal description text headers should be amended to read ``Cortez
Municipal Airport'' to match the FAA's database. Reference to the
Cortez VOR/distance measuring equipment (DME) on line three of the
airport's legal descriptions is no longer needed and should be removed.
The airspace should be described using the airport reference point. The
Class E surface area legal description should be updated to replace the
outdated use of the phrases ``Notice to Airmen'' and ``Airport/Facility
Directory.'' These phrases should read ``Notice to Air Missions'' and
``Chart Supplement,'' respectively, to align with the FAA's current
nomenclature.
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.
