Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain The Boeing Company Model 

737–8 and Model 737–9 airplanes. This 

proposed AD was prompted by a Boeing 

review of the standby power system 

control unit (SPCU) design where a 

single point of failure exists internal to 

the SPCU. This proposed AD would 

require the installation of four diodes 

and changing wire bundles in the P5 

panel, as well as performing installation 

and power tests and applicable oncondition actions. The FAA is 

proposing this AD to address the unsafe 

condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by April 1, 2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

SUPPLEMENTARY INFORMATION: 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this proposal. Send 

your comments to an address listed 

under ADDRESSES. Include ‘‘Docket No. 

FAA–2024–0229; Project Identifier AD– 

2023–00485–T’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the 

proposal, explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this proposal 

because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to 

regulations.gov, including any personal 

information you provide. The agency 

will also post a report summarizing each 

substantive verbal contact received 

about this NPRM. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 


ddrumheller on DSK120RN23PROD with PROPOSALS1
11232 Federal Register / Vol. 89, No. 31 / Wednesday, February 14, 2024 / Proposed Rules 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Hoang Yen Dang, 

Aviation Safety Engineer, FAA, 2200 

South 216th St., Des Moines, WA 98198; 

telephone 206–231–3610; email 

Hoang.Yen.T.Dang@faa.gov. Any 

commentary that the FAA receives that 

is not specifically designated as CBI will 

be placed in the public docket for this 

rulemaking. 

Background 

The FAA has received a report 

indicating that a Boeing review of the 

SPCU design revealed that a potential 

single point of failure exists internal to 

the SPCU. This condition, if not 

addressed, could result in a non-latent 

single point of failure, which can result 

in a non-latent loss of the entire battery 

buss and consequent un-annunciated 

loss of control and indication of both 

engine anti-ice (EAI) systems. 

The unsafe condition, if not 

addressed, could result in loss of thrust 

on both engines due to damage from 

operation in icing conditions without 

EAI and can result in loss of continued 

safe flight and landing. 

FAA’s Determination 

The FAA is issuing this NPRM after 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 737–30A1083 

RB, dated November 18, 2022. This 

service information specifies procedures 

for the installation of four diodes and 

changing wire bundles in the P5 panel, 

as well as performing an anti-ice diode 

installation test and an engine anti-ice 

and wing anti-ice power test and 

applicable on-condition actions. Oncondition actions include doing 

applicable corrective actions until the 

tests are passed. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in ADDRESSES. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

the service information already 

described and except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Interim Action. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 205 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Installation, Wiring bundle 

changes, and tests.

Up to 18 work-hours × $85 per 

hour = Up to $1,530.

Up to $3,760 ........... Up to $5,290 ........... Up to $1,084,450. 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition actions specified in 

this proposed AD. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. 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. 

The FAA is issuing this rulemaking 

under the authority described in 

Subtitle VII, Part A, Subpart III, Section 

44701: General requirements. Under 

that section, Congress charges the FAA 

with promoting safe flight of civil 

aircraft in air commerce by prescribing 

regulations for practices, methods, and 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

The FAA determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national Government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

CORPORATION FOR NATIONAL AND 

COMMUNITY SERVICE 

45 CFR Parts 2551, 2552, and 2553 

RIN 3045–AA81 

AmeriCorps Seniors Regulation 

Updates 

AGENCY: Corporation for National and 

Community Service. 

ACTION: Proposed rule with request for 

comments. 

SUMMARY: The Corporation for National 

and Community Service (operating as 

AmeriCorps) proposes to revise its 

regulations governing AmeriCorps 

Seniors programs. This proposed rule 

would remove barriers to service for 

individuals and increase flexibility for 

sponsors to determine the best mix of 

staffing and resources to accomplish 

project goals. Specifically, this proposed 

rule would remove barriers for 

individuals to serve as AmeriCorps 

Seniors volunteers in three ways: first, 

by limiting what is considered income 

in the calculation that determines 

eligibility to receive a stipend; second, 

by allowing volunteers to continue to 

receive a stipend when their sponsor 

places them on administrative leave due 

to extenuating circumstances that 

prevent service; and third, by allowing 

sponsors to supplement stipends. This 

proposed rule would increase flexibility 

for AmeriCorps Seniors sponsors in 

three ways: first, by removing the 

prescriptive requirement for them to 

employ a full-time project director; 

second, by establishing a single 10 

percent match value regardless of grant 

year; and third, by allowing sponsors to 

choose to pay more than (but not less 

than) the AmeriCorps-established 

stipend rates using non-AmeriCorps 

funds for the amount exceeding the 

AmeriCorps-established rate. These 

proposed changes would allow sponsors 

to determine the best staffing and 

volunteer mix to support projects and 

how to devote resources that would 

otherwise be devoted to meet 

increasingly high match requirements. 

This proposed rule would also update 

nomenclature to reflect that the 

Corporation for National and 

Community Service operates as 

AmeriCorps and that ‘‘Senior Corps’’ is 

now known as ‘‘AmeriCorps Seniors.’’

submitted by April 15, 2024.
