Effect on the Supervisory Relationship As noted previously, the CFPB encourages an open dialogue with its supervised entities and views appeals as one aspect of such dialogue. As such, the CFPB will take measures to ensure that an entity’s filing of an appeal does not have a negative effect on its supervisory relationship with the CFPB. Any entity with concerns about its relationship with the CFPB should contact the CFPB’s Ombudsman who will handle such concerns in a confidential manner, if requested. Information on how to contact the Ombudsman can be found at https:// www.consumerfinance.gov/ ombudsman/. III. Regulatory Matters This supervisory appeals process is a rule of agency organization, procedure, or practice under the Administrative Procedure Act.14 The CFPB has determined that this supervisory appeals process does not impose any new or revise any existing recordkeeping, reporting, or disclosure requirements on covered entities or members of the public that would be collections of information requiring approval by the Office of Management and Budget under the Paperwork Reduction Act.15 Rohit Chopra, Director, Consumer Financial Protection Bureau.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2021–13–07, Amendment 39–21612 (86 FR 31601, June 15, 2021), (AD 2021–13–07). AD 2021–13–07 applied to all GEAC Model M601D–11, M601E–11, M601E–11A, M601E–11AS, M601E–11S, and M601F engines. AD 2021–13–07 required recalculating the life of critical parts and, depending on the results of the recalculation, replacing critical parts. AD 2021–13–07 also requires replacing a certain compressor case. The FAA issued AD 2021–13–07 to prevent the failure of the engine. The NPRM published in the Federal Register on October 27, 2023 (88 FR 73778). The NPRM was prompted by EASA AD 2021–0125R1, dated January 30, 2023 (EASA AD 2021–0125R1) (also referred to as the MCAI), issued by EASA, which is the Technical Agent for the Member States of the European Union. The MCAI states that the manufacturer published the ALS, which incorporates certain requirements addressed by EASA Emergency AD 2021–0125–E, and that EASA published EASA AD 2023–0020, dated January 23, 2023 (EASA AD 2023–0020), which requires accomplishment of the actions specified in the ALS. The MCAI limits the applicability to M601E engines with a centrifugal compressor case having part number M601–154.61 installed and removes the requirements that have been incorporated in the ALS. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–2002. In the NPRM, the FAA proposed to continue to require the replacement of a certain centrifugal compressor case. In the NPRM, the FAA also proposed to require accomplishing the actions specified in the MCAI. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs. E:\FR\FM\22FER1.SGM 22FER1 13266 Federal Register / Vol. 89, No. 36 / Thursday, February 22, 2024 / Rules and Regulations Conclusion These products have been approved by the aviation authority of another country and are 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 referenced above.

Except for minor editorial changes, this AD is adopted as proposed in the NPRM. course of business or by the means identified in ADDRESSES. Related Service Information Under 1 CFR Part 51 Differences Between This AD and the MCAI The FAA reviewed EASA AD 2021– 0125R1, which specifies procedures for replacing the centrifugal compressor case, limits the applicability to certain M601E engines, and removes the requirements that have been incorporated in the ALS. This service information is reasonably available because the interested parties have access to it through their normal The MCAI applies to GEAC Model M601E engines, and this AD does not because they do not have an FAA type certificate. Costs of Compliance The FAA estimates that this AD affects 13 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS Recalculate centrifugal compressor case equivalent flight cycles. Replace centrifugal compressor case ............ 1 work-hour × $85 per hour = $85 ................. $0 $85 $1,105 10 work-hours × $85 per hour = $850 ........... 65,000 65,850 856,050 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 has determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and VerDate Sep<11>2014 15:55 Feb 21, 2024 Jkt 262001 Parts cost Cost on U.S. operators Labor cost Authority for This Rulemaking lotter on DSK11XQN23PROD with RULES1 Cost per product Action (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

The CARS Rule was to become effective on July 30, 2024. Because of a pending legal challenge, this document announces that the effective date of the Final Rule is delayed until further notice. SUMMARY: The effective date of the final rule adding 16 CFR part 463, published at 89 FR 590, January 4, 2024, is delayed indefinitely.

SUPPLEMENTARY INFORMATION: I. Background 1 On January 4, 2024, the Commission published a Final Rule in the Federal Register, titled ‘‘Combating Auto Retail Scams Trade Regulation Rule,’’ to curtail certain unfair or deceptive acts or practices by motor vehicle dealers. See 89 FR 590 (Jan. 4, 2024).2 The CARS 1 This section is substantively identical to the order that the Commission issued on January 18, 2024. See Order Postponing Effective Date of Final Rule Pending Judicial Review, In re Combating Auto Retail Scams Trade Regulation Rule, No. P204800 (Jan. 18, 2024), https://www.ftc.gov/ system/files/ftc_gov/pdf/P204800CARS ExtensionOrder.pdf. 2 In accordance with its rulemaking authority under 12 U.S.C. 5519(d), the Commission promulgated the CARS Rule pursuant to 15 U.S.C. 45 and 57a(a)(1)(B) and 5 U.S.C. 553. 12 U.S.C. 5519(f)(1) and (f)(2) contain the pertinent definitions of ‘‘motor vehicle’’ and ‘‘motor vehicle dealer,’’ and the Rule applies only to a ‘‘covered’’ subset. See 89 FR 590, 693–94 (Jan. 4, 2024) (to be codified at 16 CFR 462.3(e) through (f)). PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 13267 Rule was to become effective on July 30, 2024. On or about January 5, 2024, the National Automobile Dealers Association and the Texas Automobile Dealers Association (‘‘Petitioners’’) filed a Petition for Review (‘‘PFR’’) in the United States Court of Appeals for the Fifth Circuit. Nat’l Auto. Dealers Ass’n v. FTC, No. 24–60013 (5th Cir. filed Jan. 5, 2024). On January 8, 2024, the Petitioners filed a motion with the Fifth Circuit seeking a stay of the Rule and expedited consideration of their PFR. Although Petitioners did not seek a stay from the Commission in the first instance as required by Rule 18(a)(1) of the Federal Rules of Appellate Procedure, the Commission has nonetheless reviewed Petitioners’ motion, construing it as though it were a stay request submitted under Commission Rule 4.2(d), 16 CFR 4.2(d). The Administrative Procedure Act (‘‘APA’’) provides, in relevant part, that ‘‘[w]hen an agency finds that justice so requires, it may postpone the effective date of action taken by it, pending judicial review.’’ See 5 U.S.C. 705. The Commission believes the Rule will provide consumers with critical protections from auto retail scams, Petitioners’ challenges to the Rule lack merit, and undue delay in the Rule’s effective date will harm consumers and honest businesses. Petitioners’ arguments for a stay rest on mischaracterizations of what the Rule requires of covered motor vehicle dealers, including inaccurate claims that the Rule will require dealers to overhaul their practices and will substantially increase compliance costs. In fact, the Rule does not impose substantial costs, if any, on dealers that presently comply with the law, and to the extent there are costs, those are outweighed by the benefits to consumers, to law-abiding dealers, and to fair competition— because honest dealers will no longer be at a competitive disadvantage relative to dishonest dealers. Nonetheless, Petitioners have created uncertainty through their assertions and suggestions that legally compliant dealers must make unnecessary changes to satisfy Petitioners’ misunderstandings of the Rule. Additionally, Petitioners are seeking expedited consideration of the PFR, and, if that request is granted, the stay of the effective date should not postpone implementation of the Rule by more than a few months, if at all. Balancing the equities here, the Commission has determined it is in the interests of justice to stay the effective date of the Rule to allow for judicial review. Once the PFR’s merits are resolved, the Commission will publish a E:\FR\FM\22FER1.SGM 22FER1

Airworthiness Directives; GE Aviation Czech s.r.o. (Type 
Certificate Previously Held by WALTER Engines a.s., Walter a.s., and 
MOTORLET a.s.) Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-13-07 
for all GE Aviation Czech s.r.o. (GEAC) (type certificate previously 
held by WALTER Engine a.s., Walter a.s., and MOTORLET a.s.) Model 
M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, and M601F 
engines. AD 2021-13-07 required recalculating the life of critical 
parts and, depending on the results of the recalculation, replacing 
those critical parts. AD 2021-13-07 also required replacing a certain 
compressor case. Since the FAA issued AD 2021-13-07, the manufacturer 
published the airworthiness limitations section (ALS) of the existing 
engine maintenance manual (EMM), which includes the calculations for 
the life of critical parts addressed by AD 2021-13-07 and prompted this 
AD. This AD continues to require the replacement of a certain 
centrifugal compressor case. This AD also includes an additional part 
number as an option for the replacement, and limits the applicability 
of this AD, as specified in a European Union Aviation Safety Agency 
(EASA) AD, which is incorporated by reference. The FAA is issuing this 
AD to address the unsafe condition on these products.

DATES: This AD is effective March 28, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 28, 
2024.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2021-13-07, Amendment 39-21612 (86 FR 
31601, June 15, 2021), (AD 2021-13-07). AD 2021-13-07 applied to all 
GEAC Model M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, and 
M601F engines. AD 2021-13-07 required recalculating the life of 
critical parts and, depending on the results of the recalculation, 
replacing critical parts. AD 2021-13-07 also requires replacing a 
certain compressor case. The FAA issued AD 2021-13-07 to prevent the 
failure of the engine.
    The NPRM published in the Federal Register on October 27, 2023 (88 
FR 73778). The NPRM was prompted by EASA AD 2021-0125R1, dated January 
30, 2023 (EASA AD 2021-0125R1) (also referred to as the MCAI), issued 
by EASA, which is the Technical Agent for the Member States of the 
European Union. The MCAI states that the manufacturer published the 
ALS, which incorporates certain requirements addressed by EASA 
Emergency AD 2021-0125-E, and that EASA published EASA AD 2023-0020, 
dated January 23, 2023 (EASA AD 2023-0020), which requires 
accomplishment of the actions specified in the ALS. The MCAI limits the 
applicability to M601E engines with a centrifugal compressor case 
having part number M601-154.61 installed and removes the requirements 
that have been incorporated in the ALS.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-2002.
    In the NPRM, the FAA proposed to continue to require the 
replacement of a certain centrifugal compressor case. In the NPRM, the 
FAA also proposed to require accomplishing the actions specified in the 
MCAI.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

[[Page 13266]]

Conclusion

    These products have been approved by the aviation authority of 
another country and are 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 referenced above. The FAA reviewed the relevant data and 
determined that air safety requires adopting this AD as proposed. 
Accordingly, the FAA is issuing this AD to address the unsafe condition 
on these products. Except for minor editorial changes, this AD is 
adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2021-0125R1, which specifies procedures 
for replacing the centrifugal compressor case, limits the applicability 
to certain M601E engines, and removes the requirements that have been 
incorporated in the ALS.
    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.

Differences Between This AD and the MCAI

    The MCAI applies to GEAC Model M601E engines, and this AD does not 
because they do not have an FAA type certificate.

Costs of Compliance

    The FAA estimates that this AD affects 13 engines installed on

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 has determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

reference, Safety.

The Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

a. Removing Airworthiness Directive 2021-13-07, Amendment 39-21612 (86 
FR 31601, June 15, 2021); and
0
b. Adding the following new airworthiness directive:

2024-02-04 GE Aviation Czech s.r.o. (Type Certificate Previously 
held by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.): 
Amendment 39-22668; Docket No. FAA-2023-2002; Project Identifier 
MCAI-2023-00176-E.

(a) Effective Date

    This airworthiness directive (AD) is effective March 28, 2024.

(b) Affected ADs

June 15, 2021) (AD 2021-13-07).

(c) Applicability

    This AD applies to GE Aviation Czech s.r.o. (type certificate 
previously held by WALTER Engines a.s., Walter a.s., and MOTORLET 
a.s.) Model M601E-11, M601E-11A, M601E-11AS, and M601E-11S engines 
with a centrifugal compressor case having part number (P/N) M601-
154.61 installed.

(d) Subject

    Joint Aircraft System Component (JASC) Code 7230, Turbine Engine 
Compressor Section.

(e) Unsafe Condition

    This AD was prompted by the manufacturer determining that the 
life limit of a compressor case having P/N M601-154.61 is not listed 
in the airworthiness limitations section of the existing engine 
maintenance manual. The FAA is issuing this AD to prevent the 
failure of the engine. The unsafe condition, if not addressed, could 
result in uncontained release of a critical part, damage to the 
engine, and damage to the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Except as specified in paragraph (h) of this AD: Perform all 
required actions within the compliance times specified in, and in
