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 Airbus Canada Limited 

Partnership Model BD–500–1A10 and 

BD–500–1A11 airplanes. This proposed 

AD was prompted by certification 

testing that found that environmental 

control system (ECS) ducts 

manufactured using a certain material 

failed the flammability test 

requirements established for 

compliance. This proposed AD would 

require inspecting the affected ECS 

ducts and, as applicable, installing a 

fire-resistant sleeve assembly over any 

non-compliant ECS duct, and prohibit 

the installation of ECS ducts as 

replacement parts under certain 

conditions, as specified in a Transport 

Canada 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 March 31, 2025. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

will consider all comments received by 

the closing date and may amend this 

proposal because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to 

regulations.gov, including any personal 

information you provide. The agency 

will also post a report summarizing each 

substantive verbal contact received 

about this NPRM. 

Confidential Business Information 

CBI is commercial or financial

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 Brenda Buitrago Perez, 

Aviation Safety Engineer, FAA, 2200 

South 216th St., Des Moines, WA 98198; 

telephone 516–228–7368; email 

brenda.l.buitrago.perez@faa.gov. Any 

commentary that the FAA receives that 

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–2024– 

21, dated June 20, 2024 (Transport 

Canada AD CF–2024–21) (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 ECS ducts, located on 

forward and aft cargo compartment 

ceiling panels, having part numbers (P/ 

Ns) D761189–105, D761189–501, and 

D762232–509, have been manufactured 

using material APF1180–7781, which 

replaced discontinued legacy material 

Solvay L591PG–7781. The material 

change to APF1180–7781 was done 

without changing the ECS duct part 

number. Subsequent certification testing 

of the ECS ducts made using material 

APF1180–7781 failed flammability test 

requirements. These noncompliant ECS 

ducts may have been installed on 

certain affected airplanes during 

production. Noncompliant ECS ducts 

could result in the inability to contain 

a fire within the cargo compartment, 

which could result in an uncontrolled 

fire. 

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–2025–0199. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

Transport Canada AD CF–2024–21 

specifies procedures for inspecting to 

determine the lot numbers of affected 

ECS ducts and installing a fire-resistant 

sleeve assembly over any non-compliant 

ECS duct. Transport Canada AD CF– 

2024–21 also prohibits the installation 

of ECS ducts as replacement parts under 

certain conditions. 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 require 

accomplishing the actions specified in 

Transport Canada AD CF–2024–21 

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– 

2024–21 by reference in the FAA final 

rule. This proposed AD would, 

therefore, require compliance with 

Transport Canada AD CF–2024–21 in its 

entirety through that incorporation, 

except for any differences identified as 

exceptions in the regulatory text of this 

proposed AD. Material required by 

Transport Canada AD CF–2024–21 for 

compliance will be available at 

regulations.gov under Docket No. FAA– 

2025–0199 after the FAA final rule is 

published. 


ddrumheller on DSK120RN23PROD with PROPOSALS1
9528 Federal Register / Vol. 90, No. 29 / Thursday, February 13, 2025 / Proposed Rules 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 11 

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 

12 work-hours × $85 per hour = $1,020 ..................................................................................... $0 $1,020 $11,220 

The FAA estimates the following 

costs to do any necessary on-condition 

actions that would be required based on 

the results of any required actions. The 

FAA has no way of determining the 

number of aircraft that might need these 

on-condition actions: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per product 

2 work-hours × $85 per hour = $170 .............................................................................................................. (*) * $170 

* The FAA has received no definitive data on which to base the cost estimates for the parts cost specified in this proposed AD. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part

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

(Transport Canada AD CF–2024–21). 

(d) Subject 

Air Transport Association (ATA) of 

America Code 25, Equipment/furnishings. 

(e) Unsafe Condition 

This AD was prompted by certification 

testing that found that environmental control 

system (ECS) ducts manufactured using 

material APF1180–7781 failed the 

flammability test requirements established 

for compliance. The FAA is issuing this AD 

to address noncompliant ECS ducts that 

could cause an inability to contain a fire 

within the cargo compartment. The unsafe 

condition, if not addressed, could result in an 

uncontrolled fire. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2023–10–08, which applies to all ATR— 

GIE Avions de Transport Re ́gional 

Model ATR42–200, ATR42–300, and 

ATR42–320 airplanes. AD 2023–10–08 

requires revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

Since the FAA issued AD 2023–10–08, 

the FAA has determined that new or 

more restrictive airworthiness 

limitations are necessary. This proposed 

AD would continue to require certain 

actions in AD 2023–10–08 and 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. 

DATES: The FAA must receive comments 

on this proposed AD by March 31, 2025. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to
