II. Discussion On September 8, 2023, the NRC requested comments on a regulatory basis titled ‘‘Increased Enrichment of Conventional and Accident Tolerant Fuel Designs for Light-Water Reactors’’ to support a rulemaking that would amend the NRC’s regulations to facilitate the use of light-water reactor fuel containing uranium enriched to greater than 5.0 weight percent uranium-235 (U–235) in part 50 of title 10 of the Code of Federal Regulations (10 CFR), ‘‘Domestic Licensing of Production and Utilization Facilities,’’ 10 CFR part 51, ‘‘Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions,’’ and 10 CFR part 71, ‘‘Packaging and Transportation of Radioactive Material.’’ This rulemaking would allow the NRC to prepare for the effective and efficient licensing of applications using fuels enriched to greater than 5.0 and less than 20.0 weight percent U–235 without compromising reasonable assurance of adequate protection of public health and safety, reduce the need for exemptions from existing regulations and license amendment requests, provide licensees operational flexibility and certainty in licensing of accident tolerant fuel, and support the principles of good regulation. The rule changes would apply to any light-water power reactor application submitted to the NRC under 10 CFR part 50 and part 52, ‘‘Licenses, Certifications, and Approvals for Nuclear Power Plants.’’ The public comment period was originally scheduled to close on November 22, 2023.

Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF–2023– 27, dated May 4, 2023 (Transport Canada AD CF–2023–27) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus Canada Limited Partnership Model BD–500– 1A10 and BD–500–1A11 airplanes. The MCAI states that during production, a possibility of chafing between a power harness and the left side window shade at fuselage FR 65 was detected. Damage to the power harness can result in an emergency equipment failure, including the partial loss of the public address system and the inability to deploy half the passenger oxygen masks when required. The FAA is proposing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–2146. Related Service Information Under 1 CFR Part 51 Transport Canada AD CF–2023–27 specifies procedures for rerouting the power harness, which requires the modification of an insulation blanket and the installation of a standoff and a PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 76145 clamp on the left side stringer 11 between fuselage FR 65 and FR 67 to prevent damage to the harness. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in 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 referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in Transport Canada AD CF–2023–27 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate Transport Canada AD CF– 2023–27 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with Transport Canada AD CF–2023–27 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information required by Transport Canada AD CF– 2023–27 for compliance will be available at regulations.gov under Docket No. FAA–2023–2146 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 29 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: E:\FR\FM\06NOP1.SGM 06NOP1 76146 Federal Register / Vol. 88, No. 213 / Monday, November 6, 2023 / Proposed Rules ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 4 work-hours × $85 per hour = $340 ........................................................................ $10 $350 $10,150 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. 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: ■ Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.): Docket No. FAA– 2023–2146; Project Identifier MCAI– 2023–00646–T. (a) Comments Due Date The FAA must receive comments on this airworthiness directive (AD) by December 21, 2023. (b) Affected ADs None. (c) Applicability 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.

AGENCY: Notice of proposed rulemaking (NPRM). ACTION: The FAA proposes to supersede Airworthiness Directive (AD) 2018–14–09, which applies to certain Airbus SAS Model A318 series airplanes; Model A319 series airplanes; Model A320–211, –212, –214, –216, –231, –232, and –233 airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. AD 2018–14–09 requires repetitive inspections for cracking of the fastener holes in certain fuselage frames, and depending on airplane configuration, provides an optional terminating action to the repetitive inspections. Since the FAA issued AD 2018–14–09, it was determined that additional actions are necessary beyond those required by AD 2018–14–09. This proposed AD would continue to require the actions in AD 2018–14–09 and would require modified compliance times, as well as further inspections and optional terminating actions for certain airplanes, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR).

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 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

this rulemaking.

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2023-27, dated May 4, 2023 (Transport 
Canada AD CF-2023-27) (also referred to as the MCAI), to correct an 
unsafe condition for certain Airbus Canada Limited Partnership Model 
BD-500-1A10 and BD-500-1A11 airplanes. The MCAI states that during 
production, a possibility of chafing between a power harness and the 
left side window shade at fuselage FR 65 was detected. Damage to the 
power harness can result in an emergency equipment failure, including 
the partial loss of the public address system and the inability to 
deploy half the passenger oxygen masks when required.
    The FAA is proposing this AD to address the unsafe condition on 
these products. You may examine the MCAI in the AD docket at 
regulations.gov under Docket No. FAA-2023-2146.

Related Service Information Under 1 CFR Part 51

    Transport Canada AD CF-2023-27 specifies procedures for rerouting 
the power harness, which requires the modification of an insulation 
blanket and the installation of a standoff and a clamp on the left side 
stringer 11 between fuselage FR 65 and FR 67 to prevent damage to the 
harness.
    This material is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in 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 
referenced above. The FAA is issuing this NPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in Transport Canada AD CF-2023-27 described previously, except for any 
differences identified as exceptions in the regulatory text of this 
proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate Transport Canada AD CF-2023-27 by reference 
in the FAA final rule. This proposed AD would, therefore, require 
compliance with Transport Canada AD CF-2023-27 in its entirety through 
that incorporation, except for any differences identified as exceptions 
in the regulatory text of this proposed AD. Service information 
required by Transport Canada AD CF-2023-27 for compliance will be 
available at regulations.gov under Docket No. FAA-2023-2146 after the 
FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 29 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
