requirements of § 25.853(b) and (c) at 

Amendment 25–66. 

17. All lavatories within the crew rest 

are required to meet the same 

requirements as those for a lavatory 

installed on the main deck except with 

regard to Special Condition no. 10 for 

smoke detection. 

18. When a crew rest compartment is 

installed or enclosed as a removable 

module in part of a cargo compartment 

or is located directly adjacent to a cargo 

compartment without an intervening 

cargo compartment wall, the following 

applies: 

(a) Any wall of the module (container) 

forming part of the boundary of the 

reduced cargo compartment, subject to 

direct flame impingement from a fire in 

the cargo compartment and including 

any interface item between the module 

(container) and the airplane structure or 

systems, must meet the applicable 

requirements of § 25.855 at Amendment 

25–60. 

(b) Means must be provided so that 

the fire protection level of the cargo 

compartment meets the applicable 

requirements of §§ 25.855 at 

Amendment 25–60, 25.857 at 

Amendment 25–60 and 25.858 at 

Amendment 25–54 when the module 

(container) is not installed. 

(c) Use of each emergency evacuation 

route must not require occupants of the 

crew rest compartment to enter the 

cargo compartment in order to return to 

the passenger compartment. 

(d) The aural warning in Special 

Condition no. 7 must sound in the crew 

rest compartment in the event of a fire 

in the cargo compartment. 

19. Means must be provided to 

prevent access into the Class C cargo 

compartment during all airplane 

operations and to ensure that the 

maintenance door is closed during all 

airplane flight operations. 

20. All enclosed stowage 

compartments within the crew rest that 

are not limited to stowage of emergency 

equipment or airplane-supplied 

equipment (e.g., bedding) must meet the 

design criteria given in the table below. 

As indicated by the table below, this 

special condition does not address 

enclosed stowage compartments greater 

than 200 ft3 in interior volume. The inflight accessibility of very large, 

enclosed stowage compartments and the 

subsequent impact on the 

crewmembers’ ability to effectively 

reach any part of the compartment with 

the contents of a hand fire extinguisher 

will require additional fire protection 

considerations similar to those required 

for inaccessible compartments such as 

Class C cargo compartments.

1 Material: The material used to construct each enclosed stowage compartment must at least be fire resistant and must meet the flammability

standards established for interior components per the requirements of § 25.853. For compartments less than 25 ft3 in interior volume, the design 

must ensure the ability to contain a fire likely to occur within the compartment under normal use. 2 Detectors: Enclosed stowage compartments equal to or exceeding 25 ft3 in interior volume must be provided with a smoke or fire detection 

system to ensure that a fire can be detected within a one-minute detection time. Flight tests must be conducted to show compliance with this requirement. Each system (or systems) must provide: 

(a) A visual indication in the flight deck within one minute after the start of a fire; 

(b) An aural warning in the crew rest compartment; and 

(c) A warning in the main passenger cabin. This warning must be readily detectable by a flight attendant, taking into consideration the positioning of flight attendants throughout the main passenger compartment during various phases of flight. 3 Liner: If it can be shown that the material used to construct the stowage compartment meets the flammability requirements of a liner for a 

Class B cargo compartment, then no liner would be required for enclosed stowage compartments equal to or greater than 25 ft3 in interior volume but less than 57 ft3 in interior volume. For all enclosed stowage compartments equal to or greater than 57 ft3 in interior volume but less than 

or equal to 200 ft3, a liner must be provided that meets the requirements of § 25.855 at Amendment 25–60 for a class B cargo compartment. 4 Location Detector: Crew rest areas which contain enclosed stowage compartments exceeding 25 ft3 interior volume and which are located 

away from one central location such as the entry to the crew rest area or a common area within the crew rest area would require additional fire 

protection features and/or devices to assist the firefighter in determining the location of a fire.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2023–05–02, which applies to certain 

Airbus SAS Model A318, A319, A320 

and A321 series airplanes. AD 2023–05– 

02 requires revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

Since the FAA issued AD 2023–05–02, 

the FAA has determined that new or 

more restrictive airworthiness 

limitations are necessary. This proposed 

AD would require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations, 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.

Background 

The FAA issued AD 2023–05–02, 

Amendment 39–22371 (88 FR 15600, 

March 14, 2023) (AD 2023–05–02), for 

certain Airbus SAS Model A318, A319, 

A320 and A321 series airplanes. AD 

2023–05–02 was prompted by an MCAI 

originated by EASA, which is the 

Technical Agent for the Member States 

of the European Union. EASA issued 

AD 2022–0102, dated June 8, 2022 

(EASA AD 2022–0102) (which 

corresponds to FAA AD 2023–05–02), to 

correct an unsafe condition. 

AD 2023–05–02 requires revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

additional new or more restrictive 

airworthiness limitations. AD 2023–05– 

02 also specifies that accomplishing the 

revision of the existing maintenance or 

inspection program terminates the 

requirements of paragraphs (g) through 

(k) of AD 2018–23–02, Amendment 39– 

19488 (83 FR 59278, November 23, 

2018). The FAA issued AD 2023–05–02 

to address the risks associated with the 

effects of aging on airplane systems. 

Such effects could change system 

characteristics. The unsafe condition, if 

not addressed, could result in an 

increased potential for failure of certain 

life-limited parts, and reduced 

structural integrity of the airplane. 

Actions Since AD 2023–05–02 Was 

Issued 

Since the FAA issued AD 2023–05– 

02, EASA superseded AD 2022–0102 

and issued EASA AD 2024–0046, dated 

February 19, 2024 (EASA AD 2024– 

0046) (also referred to as the MCAI), for 

all Airbus SAS Model A318–111, –112, 

–121, and –122 airplanes; Model A319– 

111, –112, –113,–114, –115, –131, –132, 

–133, –151N, –153N, and –171N 

airplanes; Model A320–211, –212, –214, 

–215, –216, –231, –232, –233, –251N, 

–252N, –253N, –271N, –272N, and 

–273N airplanes; and Model A321–111, 

–112, –131, –211, –212, –213, –231, 232, 

–251N, –251NX, –252N, –252NX, 

–253N, –253NX, –271N, –271NX, 

–272N, and –272NX airplanes. Model 

A320–215 airplanes are not certified by 

the FAA and are not included on the 

U.S. type certificate data sheet; this 

proposed AD therefore does not include 

those airplanes in the applicability. The 

MCAI states that new or more restrictive 

airworthiness limitations have been 

developed. 

Airplanes with an original 

airworthiness certificate or original 

export certificate of airworthiness 

issued after November 6, 2023, must 

comply with the airworthiness 

limitations specified as part of the 

approved type design and referenced on 

the type certificate data sheet; this 

proposed AD therefore does not include 

those airplanes in the applicability. 

The FAA is proposing this AD to 

address the risks associated with the 

effects of aging on airplane systems. 

Such effects could change system 

characteristics. The unsafe condition, if 

not addressed, could result in an 

increased potential for failure of certain 

life-limited parts, and reduced 

structural integrity of the airplane. You 

may examine the MCAI in the AD 

docket at regulations.gov under Docket 

No. FAA–2024–2139. 

Material Incorporated by Reference

The FAA reviewed EASA AD 2024– 

0046. This material specifies new or

limitations for airplane structures and 

safe life limits. 

This proposed AD would also require 

EASA AD 2022–0102, which the 

Director of the Federal Register 

approved for incorporation by reference 

as of April 18, 2023 (88 FR 15600, 

March 14, 2023). 

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 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 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 retain all of 

the requirements of AD 2023–05–02. 

This proposed AD would also require 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate additional new or more 

restrictive airworthiness limitations, 

which are specified in EASA AD 2024– 

0046 already described, as proposed for 

incorporation by reference. Any 

differences with EASA AD 2024–0046 

are identified as exceptions in the 

regulatory text of this AD. 

This proposed AD would require 

revisions to certain operator 

maintenance documents to include new 

actions (e.g., inspections). Compliance 

with these actions is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired 

in the areas addressed by this proposed 

AD, the operator may not be able to 

accomplish the actions described in the 

revisions. In this situation, to comply 

with 14 CFR 91.403(c), the operator 

must request approval for an alternative 

method of compliance (AMOC) 

according to paragraph (n)(1) 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 

retain the IBR of EASA AD 2022–0102 

and incorporate EASA AD 2024–0046 

by reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2022–0102 

and EASA AD 2024–0046 through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Using common terms that are the same 

as the heading of a particular section in 

EASA AD 2022–0102 or EASA AD 

2024–0046 does not mean that operators 

need comply only with that section. For 

example, where the AD requirement 

refers to ‘‘all required actions and 

compliance times,’’ compliance with 

this AD requirement is not limited to 

the section titled ‘‘Required Action(s) 

and Compliance Time(s)’’ in EASA AD 

2022–0102 or EASA AD 2024–0046. 

Material required by EASA AD 2022– 

0102 and EASA AD 2024–0046 for 

compliance will be available at 

regulations.gov by searching for and 

locating Docket No. FAA–2024–2139 

after the FAA final rule is published. 

Airworthiness Limitation ADs Using 

the New Process 

The FAA’s process of incorporating 

by reference MCAI ADs as the primary 

source of information for compliance 

with corresponding FAA ADs has been 

limited to certain MCAI ADs (primarily 

those with service bulletins as the 

primary source of information for 

accomplishing the actions required by 

the FAA AD). However, the FAA is now 

expanding the process to include MCAI 

ADs that require a change to 

airworthiness limitation documents, 

such as airworthiness limitation 

sections. 

For these ADs that incorporate by 

reference an MCAI AD that changes 

airworthiness limitations, the FAA 

requirements are unchanged. Operators 

must revise the existing maintenance or 

inspection program, as applicable, to 

incorporate the information specified in 

the new airworthiness limitation 

document. The airworthiness 

limitations must be followed according 

to 14 CFR 91.403(c) and 91.409(e). 

The previous format of the 

airworthiness limitation ADs included a 

paragraph that specified that no 

alternative actions (e.g., inspections) or 

intervals may be used unless the actions 

and intervals are approved as an AMOC 

in accordance with the procedures 

specified in the AMOCs paragraph 

under ‘‘Additional AD Provisions.’’ This 

new format includes a ‘‘New Provisions 

for Alternative Actions and Intervals’’ 

paragraph that does not specifically 

refer to AMOCs, but operators may still 

request an AMOC to use an alternative 

action or interval. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 1,920 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2023–05–02 to be $7,650 (90 workhours × $85 per work-hour). 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. 

The FAA estimates the total cost per 

operator for the new proposed actions to 

be $7,650 (90 work-hours × $85 per 

work-hour). 

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.

(d) Subject 

Air Transport Association (ATA) of 

America Code 05, Time Limits/Maintenance 

Checks. 

(e) Unsafe Condition 

This AD was prompted by a determination 

that new or more restrictive airworthiness 

limitations are necessary. The FAA is issuing 

this AD to address the risks associated with 

the effects of aging on airplane systems. Such 

effects could change system characteristics. 

The unsafe condition, if not addressed, could 

result in an increased potential for failure of 

certain life-limited parts, and reduced 

structural integrity of the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Retained Revision of the Existing

changes. For airplanes with an original 

airworthiness certificate or original export 

certificate of airworthiness issued on or 

before February 18, 2022, comply with all 

required actions and compliance times 

specified in, and in accordance with, 

European Union Aviation Safety Agency 

(EASA) AD 2022–0102, dated June 8, 2022 

(EASA AD 2022–0102). Accomplishing the 

revision of the existing maintenance or 

inspection program required by paragraph (j) 

of this AD terminates the requirements of this 

paragraph. 

(h) Retained Exceptions to EASA AD 2022– 

0102, With No Changes 

This paragraph restates the exceptions

Establishment of Reporting 

Requirements for the Development of 

Advanced Artificial Intelligence Models 

and Computing Clusters 

AGENCY: Bureau of Industry and 

Security, Department of Commerce. 

ACTION: Proposed rule; request for 

comment 

SUMMARY: This proposed rule would 

amend the Bureau of Industry and 

Security’s (BIS) Industrial Base 

Surveys—Data Collections regulations 

by establishing reporting requirements 

for the development of advanced 

artificial intelligence (AI) models and 

computing clusters under the Executive 

order of October 30, 2023, ‘‘Safe, Secure, 

and Trustworthy Development and Use 

of Artificial Intelligence.’’ 

DATES: Comments on this proposed rule 

must be received by BIS by no later than 

October 11, 2024. 

ADDRESSES: Comments on this proposed 

rule may be submitted to the Federal 

rulemaking portal 

(www.regulations.gov). The 

regulations.gov ID for this proposed rule 

is: BIS–2024–0047. Please refer to RIN 

0694–AJ55 in all comments. 

Anyone submitting business 

confidential information should clearly 

identify any business confidential 

portion of a comment at the time of 

submission, file a statement justifying 

nondisclosure and referring to the 

specific legal authority claimed, and 

provide a non-confidential version of 

the submission. 

For comments submitted 

electronically containing business 

confidential information, the file name 

of the business confidential version 

should begin with the characters ‘‘BC.’’ 

Any page containing business 

confidential information must be clearly 

marked ‘‘BUSINESS CONFIDENTIAL’’ 

on the top of that page. The 

corresponding non-confidential version

SUPPLEMENTARY INFORMATION: 

Background 

Section 4.2(a)(i) of Executive Order 

14110 of October 30, 2023, ‘‘Safe, 

Secure, and Trustworthy Development 

and Use of Artificial Intelligence’’ (E.O. 

14110), directs the Secretary of 

Commerce to require companies 

developing, or demonstrating an intent 

to develop, potential dual-use 

foundation AI models to provide certain 

information to the Federal Government 

on an ongoing basis. Additionally, 

section 4.2(a)(ii) of E.O. 14110 directs 

the Secretary of Commerce to require 

companies, individuals, or other 

organizations or entities that acquire, 

develop, or possess a potential largescale computing cluster to report any 

such acquisition, development, or 

possession, including the existence and 

location of these clusters and the 

amount of total computing power 

available in each cluster. 

As defined under E.O. 14110, a ‘‘dualuse foundation model’’ is ‘‘trained on 

broad data; generally uses selfsupervision; contains at least tens of 

billions of parameters; is applicable 

across a wide range of contexts; and that 

exhibits, or could be easily modified to 

exhibit, high levels of performance at 

tasks that pose a serious risk to security, 

national economic security, national 

public health or safety, or any 

combination of those matters.’’ The 

reporting requirements proposed in this 

regulation are intended to apply to dualuse foundation models that meet 

technical conditions issued by the 

Department. The Department expects to 

update the technical conditions, based 

on technological advancements, as
