Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all MHI RJ Aviation ULC Model CL–600–2C10 (Regional Jet Series 700, 701 & 702); CL–600–2C11 (Regional Jet Series 550); CL–600–2D15 (Regional Jet Series 705); CL–600–2D24 (Regional Jet Series 900); and CL–600–2E25 (Regional Jet Series 1000) airplanes. The NPRM published in the Federal Register on July 21, 2022 (87 FR 43450). The NPRM was prompted by AD CF–2021–49, dated December 20, 2021, issued by Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that the landing gear age of certain airplanes was higher than expected for gear overhaul. The MCAI notes that undetected corrosion could lead to MLG and/or NLG collapse, and consequent damage to the airplane and injury to the occupants. In the NPRM, the FAA proposed to require verifying the calendar age of the NLG and MLG by way of component maintenance documents, and performing corrective actions if necessary. The NPRM also proposed to prohibit installing certain components. The FAA is issuing 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–2022–0885. 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 reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 MHI RJ has issued Service Bulletin 670BA–32–062, dated December 2, 2021. This service information describes procedures for, among other actions, verifying the calendar age of the NLG and MLG by way of component maintenance documents and for removing affected landing gear components and replacing them with serviceable components. This service information 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. Costs of Compliance The FAA estimates that this AD affects 624 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: khammond on DSKJM1Z7X2PROD with RULES ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 4 work-hours × $85 per hour = $340 .......................................................................................... $0 $340 $212,160 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 Up to 32 work-hours × $85 per hour = Up to $2,720 ................................................ Up to $340,000 ....................

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.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all MHI RJ Aviation ULC 
Model CL-600-2C10 (Regional Jet Series 700, 701 & 702); CL-600-2C11 
(Regional Jet Series 550); CL-600-2D15 (Regional Jet Series 705); CL-
600-2D24 (Regional Jet Series 900); and CL-600-2E25 (Regional Jet 
Series 1000) airplanes. The NPRM published in the Federal Register on 
July 21, 2022 (87 FR 43450). The NPRM was prompted by AD CF-2021-49, 
dated December 20, 2021, issued by Transport Canada Civil Aviation 
(TCCA), which is the aviation authority for Canada (referred to after 
this as the MCAI). The MCAI states that the landing gear age of certain 
airplanes was higher than expected for gear overhaul. The MCAI notes 
that undetected corrosion could lead to MLG and/or NLG collapse, and 
consequent damage to the airplane and injury to the occupants.
    In the NPRM, the FAA proposed to require verifying the calendar age 
of the NLG and MLG by way of component maintenance documents, and 
performing corrective actions if necessary. The NPRM also proposed to 
prohibit installing certain components. The FAA is issuing 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-2022-0885.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    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 reviewed the relevant data and determined 
that air safety requires adopting this AD as proposed. Accordingly, the 
FAA is issuing this AD to address the unsafe condition on this product. 
Except for minor editorial changes, this AD is adopted as proposed in 
the NPRM. None of the changes will increase the economic burden on any 
operator.

Related Service Information Under 1 CFR Part 51

    MHI RJ has issued Service Bulletin 670BA-32-062, dated December 2, 
2021. This service information describes procedures for, among other 
actions, verifying the calendar age of the NLG and MLG by way of 
component maintenance documents and for removing affected landing gear 
components and replacing them with serviceable components. This service 
information 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.

Costs of Compliance

    The FAA estimates that this AD affects 624 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340...........................              $0             $340         $212,160
----------------------------------------------------------------------------------------------------------------

    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 32 work-hours x $85 per     Up to $340,000....  Up to $342,720.

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,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
