Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF–2023– 39, dated June 6, 2023 (Transport Canada AD CF–2023–39) (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 an interference condition was found during airplane manufacturing between the pilot valve fittings and their mating holes in the rear spar of the CWB.

Such significant fuel leak, combined with a potential ignition source such as a failure of a bleed duct or a failure of wires/connectors in these areas, could create a fire hazard on the airplane. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–2229. Explanation of Required Compliance Information Related Service Information Under 1 CFR Part 51 Transport Canada AD CF–2023–39 specifies procedures for replacing the pilot valve fittings with redesigned fittings. 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 AD after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Requirements of This AD This AD requires accomplishing the actions specified in Transport Canada 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, Transport Canada AD CF–2023–39 is incorporated by reference in this AD. This AD requires compliance with Transport Canada AD CF–2023–39 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Service information required by Transport Canada AD CF–2023–39 for compliance will be available at regulations.gov under Docket No. FAA–2023–2229 after this AD is published. FAA’s Justification and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause,’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. There are currently no domestic operators of these products. Accordingly, notice and opportunity for prior public comment are unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the forgoing reason(s), the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days. Regulatory Flexibility Act (RFA) The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. Costs of Compliance Currently, there are no affected U.S.registered airplanes. If an affected airplane is imported and placed on the U.S. Register in the future, the FAA provides the following cost estimates to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product 30 work-hours × $85 per hour = $2,550 ................................................................................................................. $7,549 $10,099 khammond on DSKJM1Z7X2PROD with RULES According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate. 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 VerDate Sep<11>2014 16:02 Dec 15, 2023 Jkt 262001 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. government and the States, or on the distribution of power and responsibilities among the various levels of government.

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2023-39, dated June 6, 2023 (Transport 
Canada AD CF-2023-39) (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 an 
interference condition was found during airplane manufacturing between 
the pilot valve fittings and their mating holes in the rear spar of the 
CWB. The interference condition could damage the fitting and result in 
the fitting's failure under induced fatigue. Fitting failure could lead 
to a failure of its shroud attachment and subsequent fuel leak into the 
area

[[Page 87330]]

behind the rear spar and into the landing gear bay. Such significant 
fuel leak, combined with a potential ignition source such as a failure 
of a bleed duct or a failure of wires/connectors in these areas, could 
create a fire hazard on the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-2229.

Related Service Information Under 1 CFR Part 51

    Transport Canada AD CF-2023-39 specifies procedures for replacing 
the pilot valve fittings with redesigned fittings. 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 AD after determining that the 
unsafe condition described previously is likely to exist or develop on 
other products of the same type design.

Requirements of This AD

    This AD requires accomplishing the actions specified in Transport 
Canada AD CF-2023-39 described previously, except for any differences 
identified as exceptions in the regulatory text of this 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, 
Transport Canada AD CF-2023-39 is incorporated by reference in this AD. 
This AD requires compliance with Transport Canada AD CF-2023-39 in its 
entirety through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this AD. Service 
information required by Transport Canada AD CF-2023-39 for compliance 
will be available at regulations.gov under Docket No. FAA-2023-2229 
after this AD is published.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    There are currently no domestic operators of these products. 
Accordingly, notice and opportunity for prior public comment are 
unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the 
forgoing reason(s), the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. If an 
affected airplane is imported and placed on the U.S. Register in the 
future, the FAA provides the following cost estimates to comply with 
this AD:

                  Estimated Costs for Required Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
30 work-hours x $85 per hour = $2,550.          $7,549          $10,099
------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the cost estimate.

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

    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, and
    (2) Will not affect intrastate aviation in Alaska.

The Amendment

    Accordingly, under the authority delegated to me by the 
Administrator,

[[Page 87331]]

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.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2023-24-01 Airbus Canada Limited Partnership (Type Certificate 
Previously Held by C Series Aircraft Limited Partnership (CSALP); 
Bombardier, Inc.): Amendment 39-22617; Docket No. FAA-2023-2229; 
Project Identifier MCAI-2023-00736-T.

(a) Effective Date

    This airworthiness directive (AD) is effective January 2, 2024.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Canada Limited Partnership (Type 
Certificate previously held by C Series Aircraft Limited Partnership 
(CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11 
airplanes, certificated in any category, as identified in Transport 
Canada AD CF-2023-39, dated June 6, 2023 (Transport Canada AD CF-
2023-39).

(d) Subject

    Air Transport Association (ATA) of America Code 28, Fuel.

(e) Unsafe Condition

    This AD was prompted by a reported interference between the 
pilot valve fittings and their mating holes in the rear spar of the 
center wing box. The FAA is issuing this AD to address fitting 
failure, which could lead to a failure of its shroud attachment and 
subsequent fuel leak into the area behind the rear spar and into the 
landing gear bay. Such significant fuel leak, combined with a 
potential ignition source such as a failure of a bleed duct or a 
failure of wires/connectors in these areas, could create a fire 
hazard on the airplane.

(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 
accordance with, Transport Canada AD CF-2023-39.

(h) Exception to Transport Canada AD CF-2023-39

    Where Transport Canada AD CF-2023-39 refers to its effective 
date, this AD requires using the effective date of this AD.
