Any commentary that the FAA receives which is not specifically designated as VerDate Sep<11>2014 17:16 Oct 02, 2024 Jkt 265001 CBI will be placed in the public docket for this rulemaking. Background The FAA issued AD 2022–19–09, Amendment 39–22178 (87 FR 57799, September 22, 2022) (AD 2022–19–09), for all Airbus Canada Limited Partnership Model BD–500–1A10 and BD–500–1A11 airplanes. AD 2022–19– 09 was prompted by an MCAI originated by Transport Canada, which is the aviation authority for Canada. Transport Canada issued AD CF–2021–22R1, dated May 13, 2022 (Transport Canada AD CF–2021–22R1), to correct an unsafe condition. AD 2022–19–09 requires repetitive inspections of the left and right MLG lower spindle pins to detect corrosion, and applicable repair or replacement if necessary. The FAA issued AD 2022– 19–09 to address corrosion and subsequent cracking of the MLG lower spindle pin, which could result in failure of the pin, and consequent collapse of the MLG. Actions Since AD 2022–19–09 Was Issued The preamble to AD 2022–19–09 explained that the FAA considered the requirements ‘‘interim action’’ and was considering further rulemaking. The FAA has now determined that further rulemaking is indeed necessary, and this proposed AD follows from that determination. Since the FAA issued AD 2022–19– 09, Transport Canada superseded AD CF–2021–22R1 and issued AD CF– 2023–66, dated October 3, 2023 (Transport Canada AD CF–2023–66) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus Canada Limited Partnership Model BD– 500–1A10 and Model BD–500–1A11 airplanes. The MCAI states that the tracking of usage was changed from the MLG to the MLG lower spindle assembly for inspections. The MCAI also states that the replacement of the MLG lower spindle assembly, P/N 4115A0500–01, 4115A0500–02 or 5965A0500–01, with P/N 4115A0500– 03 on Model BD–500–1A10 airplanes, or P/N 5965A0500–02 on Model BD–500– 1A11 airplanes constitutes a terminating action to the initial and repetitive inspection requirement. The MCAI also removed airplanes from the applicability because Model BD–500– 1A10 airplanes, serial numbers 50068 and subsequent, and Model BD–500– 1A11 airplanes, serial numbers 55249 and subsequent, have a newly designed MLG lower spindle assembly installed. The FAA is proposing this AD to address the unsafe condition on these PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–2326. Explanation of Retained Requirements Although this proposed AD does not explicitly restate the requirements of AD 2022–19–09, this proposed AD would retain certain of the requirements of AD 2022–19–09. Those requirements are referenced in Transport Canada AD CF– 2023–66, which, in turn, is referenced in paragraph (g) of this proposed AD. Material Incorporated by Reference Under 1 CFR Part 51 Transport Canada AD CF–2023–66 specifies procedures for repetitive inspections (including general visual and detailed inspections, and liquid penetrant inspections) of the left and right MLG lower spindle assembly part number (P/N) 4115A0500–01, 4115A0500–02 or 5965A0500–01 for corrosion, and applicable repair or replacement of the MLG lower spindle assembly with the same P/N 4115A0500–01, 4115A0500–02, or 5965A0500–01. Transport Canada AD CF–2023–66 also specifies procedures to replace MLG lower spindle assemblies, P/N 4115A0500–01, 4115A0500–02, and 5965A0500–01, with P/N 4115A0500– 03 (for Model BD–500–1A10 airplanes), or P/N 5965A0500–02 (for Model BD– 500–1A11 airplanes), which constitutes a terminating action to the initial and repetitive inspection requirement. Transport Canada AD CF–2023–66 also prohibits the installation of MLG lower spindle assembly P/N 4115A0500–01, 415A0500–02, or 5965A0500–01 on any airplane once an airplane has installed P/N 4115A0500– 03 or P/N 5965A0500–02. 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. E:\FR\FM\03OCP1.SGM 03OCP1 80429 Federal Register / Vol. 89, No. 192 / Thursday, October 3, 2024 / Proposed Rules Proposed AD Requirements in This NPRM Explanation of Required Compliance Information This proposed AD would retain certain requirements of AD 2022–19–09. This proposed AD would require accomplishing the actions specified in Transport Canada AD CF–2023–66 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. This proposed AD would also prohibit the installation of affected parts under certain conditions. 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– 2023–66 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with Transport Canada AD CF–2023–66 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–2023–66 for compliance will be available at regulations.gov under Docket No. FAA– 2024–2326 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 98 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Parts cost Cost per product Retained actions from AD 2022– 19–09. New proposed replacement ............. Up to 25 work-hours × $85 per hour = $2,125. Up to 26 work-hours × $85 per hour = $2,210. $0 ...................... Up to $2,125 ..... Up to $37,077 ... Up to $39,287 ... 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 Cost on U.S. operators Up to $208,250 per inspection cycle. Up to $3,850,126. number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Up to 4 work-hours × $85 per hour = $340 ......................... Up to $37,077 ...................................................................... According to the manufacturer, some or all of the costs of this proposed 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. ddrumheller on DSK120RN23PROD with PROPOSALS1 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.

Airworthiness Directives; Airbus Canada Limited Partnership (Type 
Certificate Previously Held by C Series Aircraft Limited Partnership 
(CSALP); Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2022-19-09, which applies to all Airbus Canada Limited Partnership 
Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2022-19-09 requires 
repetitive inspections of the left and right main landing gear (MLG) 
lower spindle pins to detect corrosion, and applicable repair or 
replacement. Since the FAA issued AD 2022-19-09, the tracking of flight 
cycles for inspections was changed from the usage of the MLG to the 
usage of MLG lower spindle assemblies and a replacement was developed, 
which would terminate the inspections. This proposed AD continues to 
require certain actions in AD 2022-19-09, would change the tracking of 
flight cycles for inspections from the usage of the MLG to the usage of 
MLG lower spindle assemblies, and would require replacement of affected 
MLG lower spindle assemblies, as specified in a Transport Canada AD, 
which is proposed for incorporation by reference (IBR). This proposed 
AD also would remove airplanes from the applicability. This proposed AD 
would also prohibit the installation of affected parts under certain 
conditions. 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 November 
18, 2024.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    The FAA issued AD 2022-19-09, Amendment 39-22178 (87 FR 57799, 
September 22, 2022) (AD 2022-19-09), for all Airbus Canada Limited 
Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2022-19-09 
was prompted by an MCAI originated by Transport Canada, which is the 
aviation authority for Canada. Transport Canada issued AD CF-2021-22R1, 
dated May 13, 2022 (Transport Canada AD CF-2021-22R1), to correct an 
unsafe condition.
    AD 2022-19-09 requires repetitive inspections of the left and right 
MLG lower spindle pins to detect corrosion, and applicable repair or 
replacement if necessary. The FAA issued AD 2022-19-09 to address 
corrosion and subsequent cracking of the MLG lower spindle pin, which 
could result in failure of the pin, and consequent collapse of the MLG.

Actions Since AD 2022-19-09 Was Issued

    The preamble to AD 2022-19-09 explained that the FAA considered the 
requirements ``interim action'' and was considering further rulemaking. 
The FAA has now determined that further rulemaking is indeed necessary, 
and this proposed AD follows from that determination.
    Since the FAA issued AD 2022-19-09, Transport Canada superseded AD 
CF-2021-22R1 and issued AD CF-2023-66, dated October 3, 2023 (Transport 
Canada AD CF-2023-66) (also referred to as the MCAI), to correct an 
unsafe condition for certain Airbus Canada Limited Partnership Model 
BD-500-1A10 and Model BD-500-1A11 airplanes. The MCAI states that the 
tracking of usage was changed from the MLG to the MLG lower spindle 
assembly for inspections. The MCAI also states that the replacement of 
the MLG lower spindle assembly, P/N 4115A0500-01, 4115A0500-02 or 
5965A0500-01, with P/N 4115A0500-03 on Model BD-500-1A10 airplanes, or 
P/N 5965A0500-02 on Model BD-500-1A11 airplanes constitutes a 
terminating action to the initial and repetitive inspection 
requirement. The MCAI also removed airplanes from the applicability 
because Model BD-500-1A10 airplanes, serial numbers 50068 and 
subsequent, and Model BD-500-1A11 airplanes, serial numbers 55249 and 
subsequent, have a newly designed MLG lower spindle assembly installed.
    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-2024-2326.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2022-19-09, this proposed AD would retain certain of 
the requirements of AD 2022-19-09. Those requirements are referenced in 
Transport Canada AD CF-2023-66, which, in turn, is referenced in 
paragraph (g) of this proposed AD.

Material Incorporated by Reference Under 1 CFR Part 51

    Transport Canada AD CF-2023-66 specifies procedures for repetitive 
inspections (including general visual and detailed inspections, and 
liquid penetrant inspections) of the left and right MLG lower spindle 
assembly part number (P/N) 4115A0500-01, 4115A0500-02 or 5965A0500-01 
for corrosion, and applicable repair or replacement of the MLG lower 
spindle assembly with the same P/N 4115A0500-01, 4115A0500-02, or 
5965A0500-01.
    Transport Canada AD CF-2023-66 also specifies procedures to replace 
MLG lower spindle assemblies, P/N 4115A0500-01, 4115A0500-02, and 
5965A0500-01, with P/N 4115A0500-03 (for Model BD-500-1A10 airplanes), 
or P/N 5965A0500-02 (for Model BD-500-1A11 airplanes), which 
constitutes a terminating action to the initial and repetitive 
inspection requirement.
    Transport Canada AD CF-2023-66 also prohibits the installation of 
MLG lower spindle assembly P/N 4115A0500-01, 415A0500-02, or 5965A0500-
01 on any airplane once an airplane has installed P/N 4115A0500-03 or 
P/N 5965A0500-02.
    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.

[[Page 80429]]

Proposed AD Requirements in This NPRM

    This proposed AD would retain certain requirements of AD 2022-19-
09. This proposed AD would require accomplishing the actions specified 
in Transport Canada AD CF-2023-66 described previously, except for any 
differences identified as exceptions in the regulatory text of this 
proposed AD. This proposed AD would also prohibit the installation of 
affected parts under certain conditions.

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-2023-66 by reference 
in the FAA final rule. This proposed AD would, therefore, require 
compliance with Transport Canada AD CF-2023-66 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-2023-66 for compliance will be available at 
regulations.gov under Docket No. FAA-2024-2326 after the FAA final rule 
is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 98 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                                  Cost on U.S.
            Action                 Labor cost           Parts cost          Cost per product        operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2022-  Up to 25 work-    $0...................  Up to $2,125.........  Up to $208,250
 19-09.                          hours x $85 per                                                 per inspection
                                 hour = $2,125.                                                  cycle.
New proposed replacement......  Up to 26 work-    Up to $37,077........  Up to $39,287........  Up to
                                 hours x $85 per                                                 $3,850,126.
                                 hour = $2,210.
----------------------------------------------------------------------------------------------------------------

    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
----------------------------------------------------------------------------------------------------------------
Up to 4 work-hours x $85 per hour = $340.  Up to $37,077...............  Up to $37,417.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 
proposed 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

    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.
