obsolete by Congress’s termination of 

public funding for national party 

committees’ presidential nominating

REG 2019–04 (Reporting Party 

Segregated Accounts) 

On August 5, 2019, the Commission 

received a Petition for Rulemaking from 

Campaign Legal Center and Center for 

Responsive Politics (‘‘CLC/CRP 

Petition’’).13 The CLC/CRP Petition 

asked the Commission to ‘‘promulgate 

rules and forms requiring national party 

committees to delineate within their 

reports the individual and aggregate 

transactions involving’’ the accounts 

created by the Appropriations Act.14

FECA and Commission regulations 

require a political committee to report 

its receipts and disbursements.15 On 

February 13, 2015, the Commission 

issued interim guidance on how 

national party committees should report 

the activities of their party segregated 

accounts.16 The Commission noted that 

‘‘[a]lthough party committees normally 

disclose their contributions on Form 3X, 

Line 11(a), the Commission[’s] forms 

currently do not provide a clear way to 

distinguish between contributions 

deposited into the committees’ separate 

accounts.’’ The Commission instructed 

committees to report contributions to 

their party segregated accounts on Line 

17 of Form 3X titled ‘‘Other Federal 

Receipts.’’ When itemizing 

contributions in excess of $200 on 

Schedule A, the committees were 

instructed to enter ‘‘Convention 

Account,’’ ‘‘Headquarters Account,’’ or 

‘‘Recount Account,’’ as appropriate, in 

the description field. The Commission 

instructed committees to report 

administrative or operating expenses 

paid from the accounts on Line 21(b) of 

Form 3X titled ‘‘Other Federal 

Operating Expenditures’’ (for expenses 

paid from a convention or headquarters 

account) and Line 29 of Form 3X titled 

‘‘Other Disbursements’’ (for expenses 

paid from a recount account). When 

itemizing disbursements on Schedule B, 

the committees were instructed to enter 

‘‘Convention Account,’’ ‘‘Headquarters 

Account,’’ or ‘‘Recount Account,’’ as 

appropriate, in the Purpose of 

Disbursement field along with the 

required purpose of the disbursement. 

Notwithstanding this guidance, the 

CLC/CRP Petition asserted that ‘‘there is 

no consistent location or terminology 

that committees use to denote 

transactions involving’’ party segregated 

accounts.17 The CLC/CRP Petition 

claimed that ‘‘it is effectively impossible 

for the public to track the large 

quantities of funds flowing into and out 

of the [party segregated] accounts’’ 

under current Commission 

regulations.18

On August 28, 2019, the Commission 

published a Notice of Availability for 

the CLC/CRP Petition.19 The 

Commission received six timely, 

substantive comments in response. One 

comment opposed the petition; 20 three 

comments, including one from the 

petitioners, supported the petition; 21

and one comment, from the petitioner in 

REG 2014–10 (Party Contribution 

Limits), urged the Commission to 

engage in a comprehensive rulemaking 

and not to address the CLC/CRP Petition 

before acting on the Perkins Coie 

Petition.22 No national party committees 

commented on the CLC/CRP Petition. 

Request for Comments 

The Commission is continuing to 

consider whether to initiate a 

rulemaking on the issues raised in the 

Perkins Coie Petition and the CLC/CRP 

Petition (collectively, the ‘‘Petitions’’). 

Given the relatively small number of 

comments received and the party 

committees’ and the public’s additional 

experience in administering and 

interpreting the information about party 

segregated accounts, the Commission 

invites comments on the Petitions and 

any other issues pertaining to party 

segregated accounts. Have commenters’ 

or petitioners’ additional experiences 

with party segregated accounts resulted 

in further development of their 

positions? Have the national party 

committees or the public encountered 

any further challenges during election 

cycles that a rulemaking on party 

segregated accounts could help to 

resolve? 

If the Commission decides to initiate 

a rulemaking, are there any issues not 

reflected in the Petitions that the 

Commission should nonetheless 

address? Should the Commission 

consider prioritizing certain issues over 

others and, if so, which ones? The 

Commission welcomes comments on 

any other matter that could affect its 

consideration of whether to engage in a 

rulemaking. 

Dated: February 8, 2024. 

On behalf of the Commission, 

Sean J. Cooksey, 

Chairman, Federal Election Commission.

Airworthiness Directives; Bombardier, 

Inc., 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 Bombardier, Inc., Model BD– 

700–2A12 airplanes. This proposed AD 

was prompted by a report indicating 

that the fan in a transformer rectifier 

unit (TRU) can become inoperative in a 

manner that is not detectable by the fan 

monitoring circuit. This proposed AD 

would require replacement of the 

existing TRU Number 2 with a new part 

number that incorporates a correction to 

the fan and the monitoring circuit. This 

proposed AD would also prohibit the 

installation of affected parts. 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

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 

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 William Reisenauer, 

Aviation Safety Engineer, FAA, 1600 

Stewart Avenue, Suite 410, Westbury, 

NY 11590; telephone 516–228–7300; 

email 9-avs-nyaco-cos@faa.gov. Any 

commentary that the FAA receives 

which is not specifically designated as 

CBI will be placed in the public docket

Background 

Transport Canada, which is the 

aviation authority for Canada, has 

issued Transport Canada AD CF–2023– 

53, dated July 14, 2023 (Transport 

Canada AD CF–2023–53) (also referred 

to after this as the MCAI), to correct an 

unsafe condition on certain Bombardier, 

Inc., Model BD–700–2A12 airplanes. 

The MCAI states that the fan in a TRU 

can become inoperative in a manner 

that is not detectable by the fan 

monitoring circuit. An inoperative fan 

leads to higher TRU operating 

temperatures, which can trigger the 

activation of the load shed function to 

reduce the electrical load and 

temperature in the TRU. If the TRU 

temperature continues to rise and 

exceeds the maximum temperature 

threshold, the TRU will automatically 

disconnect. The shed electrical load will 

be transferred to the remaining two 

TRUs, which could lead to overheating 

and cascading failures on the remaining 

TRUs. 

In addition, a design issue was 

uncovered where the fan power-up 

built-in test (PBIT) and continuous 

built-in-test (CBIT) are not adequate to 

detect fan failure. The fan PBIT is a test 

that is automatically performed once the 

airplane is powered up. The fan PBIT 

initiates the fan to turn on regardless of 

the TRU temperature to test the fan’s 

functionality. The fan CBIT detects fan 

failure during airplane operation. 

Therefore, if FAN PBIT and/or CBIT are 

not reliable to detect a fan failure, 

inoperative fan conditions will remain 

dormant. 

It was also identified that an 

insulation blanket located close to the 

TRU 2 fan air inlet may be leading to an 

eventual reduction of TRU 2 cooling 

efficiency. 

The FAA is proposing this AD to 

address the inability of a TRU to detect 

the fan failure. The unsafe condition, if 

not addressed, could lead to overheating 

and failures on the remaining TRUs, 

which could contribute to additional 

pilot workload and adversely affect the 

safe operation of the airplane. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–0227. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Bombardier 

Service Bulletin 700–24–7507, Revision 

1, dated May 19, 2023. This service 

information specifies procedures for 

replacing the existing transformer 

rectifier unit (TRU) Number 2 part 

number (P/N) G02404521–001 with new 

P/N G02404521–003, including removal 

of the secondary layer of insulation 

blanket P/N ENM386519113D in front of 

the TRU Number 2 fan air inlet, reidentifying the blanket installation by 

ink stamp, checking the electrical bond 

resistance for TRU Number 2, and 

performing the operational test. 

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 the ADDRESSES section. 

FAA’s Determination 

This product has been approved by 

the aviation authority of another 

country and is approved for operation in 

the United States. Pursuant to the FAA’s 

bilateral agreement with this State of 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI and service information 

referenced above. 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.

11230 Federal Register / Vol. 89, No. 31 / Wednesday, February 14, 2024 / Proposed Rules 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

the service information already 

described, except as discussed under 

‘‘Difference Between this NPRM and the 

Service Information.’’ This proposed AD 

would also prohibit the installation of 

affected parts. 

Difference Between This NPRM and 

Service Information 

This AD does not require replacing 

the existing essential TRU P/N 

G02404521–001 with new P/N 

G02404521–003, as specified in 

Bombardier Service Bulletin 700–24– 

7507, Revision 1, dated May 19, 2023. 

TRU Number 2 has a higher electrical 

load than the essential TRU and, 

therefore, is more susceptible to the fan 

inoperative condition. Replacement of 

TRU Number 2, as specified in this 

proposed AD, will adequately address 

the safety concern. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 56 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

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

Up to 5 work-hours × $85 per hour = Up to $425 .......... Up to $34,754 .................... Up to $35,179 .................... Up to $1,970,024. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

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.
