88546 Federal Register / Vol. 88, No. 245 / Friday, December 22, 2023 / Proposed Rules 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

The Boeing Company: Docket No. FAA– 

2023–2398; Project Identifier AD–2023– 

00423–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by February 5, 

2024. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all The Boeing 

Company Model 787–8, 787–9, and 787–10 

airplanes, certificated in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 35, Oxygen. 

(e) Unsafe Condition 

This AD was prompted by a report 

indicating that the oxygen supply tubing can 

become kinked when certain passenger 

service unit (PSU) oxygen panel assemblies 

are installed in the forward-most position of 

a center stow bin. The FAA is issuing this AD 

to address incorrect installation of the oxygen 

supply tubing in the PSU oxygen panel 

assemblies. The unsafe condition, if not 

addressed, could result in kinked tubing and 

consequent injury of the airplane’s 

passengers because of a lack of supplemental 

oxygen during a cabin depressurization 

event. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Inspection of the Affected Parts 

For airplanes identified in Boeing Alert 

Requirements Bulletins B787–81205– 

SB250277–00 RB, Issue 001, dated February 

15, 2023, and B787–81205–SB250278–00 RB, 

Issue 001, dated February 15, 2023: Except as

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. 

Availability of Rulemaking Documents 

An electronic copy of this document 

may be downloaded through the 

internet at www.regulations.gov. 

Recently published rulemaking 

documents can also be accessed through 

the FAA’s web page at www.faa.gov/air_

traffic/publications/airspace_

amendments/. 

You may review the public docket 

containing the proposal, any comments 

received and any final disposition in 

person in the Dockets Operations office 

(see ADDRESSES section for address, 

phone number, and hours of 

operations). An informal docket may 

also be examined during normal 

business hours at the Northwest 

Mountain Regional Office of the Federal 

Aviation Administration, Air Traffic 

Organization, Western Service Center, 

Operations Support Group, 2200 S 

216th Street, Des Moines, WA 98198. 

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 


ddrumheller on DSK120RN23PROD with PROPOSALS1
88548 Federal Register / Vol. 88, No. 245 / Friday, December 22, 2023 / Proposed Rules 

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.
