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. The NRC has 

decided to extend the public comment 

period on this document until January 

22, 2024, to allow more time for 

members of the public to submit their 

comments. 

The NRC may post materials related 

to this document, including public 

comments, on the Federal rulemaking 

website at https://www.regulations.gov 

under Docket ID NRC–2020–0034. In 

addition, the Federal rulemaking

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Airbus Canada Limited 

Partnership Model BD–500–1A10 and 

BD–500–1A11 airplanes. This proposed 

AD was prompted by a report of 

possible chafing of a power harness at 

fuselage frame (FR) 65. This proposed 

AD would require rerouting the power 

harness, as specified in a Transport 

Canada AD, which is proposed for 

incorporation by reference. 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 December 21, 

2023.

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

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:

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. 

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. 

The Proposed Amendment

Airworthiness Directives; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: 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). 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 December 21, 

2023. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

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 docket of this 

NPRM. Submissions containing CBI 

should be sent to Timothy Dowling, 

Aviation Safety Engineer, FAA, 1600 

Stewart Avenue, Suite 410, Westbury, 

NY 11590; telephone 817–222–5102; 

email timothy.p.dowling@faa.gov. Any 

commentary that the FAA receives 

which is not specifically designated as 

CBI will be placed in the public docket 

for this rulemaking. 

Background 

The FAA issued AD 2018–14–09, 

Amendment 39–19329 (83 FR 34034, 

July 19, 2018) (AD 2018–14–09), for 

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 was prompted by an 

MCAI originated by EASA, which is the 

Technical Agent for the Member States 

of the European Union. EASA issued 

AD 2016–0139, dated July 14, 2016, to 

correct an unsafe condition. 

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. The FAA
