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 certain Bombardier, Inc., Model CL–600–1A11 (600), CL–600–2A12 (601), and CL–600–2B16 (601–3A, 601– 3R, and 604 Variants) airplanes. The NPRM published in the Federal Register on June 9, 2022 (87 FR 35125). The NPRM was prompted by TCCA AD CF–2021–33, dated October 6, 2021, issued by Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, (referred to after this as the MCAI). In the NPRM, the FAA proposed to require a one-time inspection of the rudder PCU load limiters for correct crimping of the end cap, and replacing any defective rudder PCU load limiter. For certain airplanes, the FAA also proposed to require repetitive testing of the rudder PCU load limiter for correct functioning, and applicable corrective actions. The FAA is issuing this AD to address defective rudder PCU load limiters, which could result in incorrect transmission of the pilot command, and loss of control of the rudder. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–0603. E:\FR\FM\21OCR1.SGM 21OCR1 63936 Federal Register / Vol. 87, No. 203 / Friday, October 21, 2022 / Rules and Regulations 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. Discussion of Final Airworthiness Directive Comments The FAA received comments from NetJets and one individual. The commenters noted the following typographical errors in the proposed AD: • For serial numbers 5701 through 5988, the service bulletin reference should be ‘‘605–27–010’’ instead of ‘‘650–27–010.’’ • For serial numbers 6050 through 6158, the service bulletin reference should be ‘‘650–27–003’’ instead of ‘‘605–27–003.’’ The FAA has corrected these errors in the Related Service Information section and in figure 1 to paragraph (g) of this AD. Related Service Information Under 1 CFR Part 51 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 Bombardier has issued the following service information. • Bombardier Service Bulletin 604– 27–039, Revision 01, dated April 6, 2021. • Bombardier Service Bulletin 600– 0776, dated December 7, 2020. • Bombardier Service Bulletin 601– 0648, dated December 7, 2020. This service information describes procedures for a one-time inspection of the rudder PCU load limiters for correct crimping of the end cap, and replacing any defective PCU load limiter. These documents are distinct because they apply to different airplane configurations. Bombardier has also released the following service information. • Bombardier Service Bulletin 605– 27–010, dated December 7, 2020. • Bombardier Service Bulletin 650– 27–003, dated December 7, 2020. This service information describes procedures for repetitive testing of certain PCU load limiters for proper functioning and applicable corrective actions (performing the one-time inspection of the rudder PCU load limiters for correct crimping of the end cap, and replacing any defective PCU load limiter). This service information also describes procedures for a one-time inspection of the rudder PCU load limiters for correct crimping of the end cap, and replacing any defective PCU load limiter, which terminates the repetitive tests. These documents are distinct because they apply to different airplane configurations. 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 379 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Cost on U.S. operators Labor cost Parts cost Cost per product Up to 2 work-hours × $85 per hour = Up to $170 ................ $0 Up to $170 .................................................... The FAA estimates the following costs to do any necessary on-condition replacement required based on the results of any required inspection. The FAA has no way of determining the Up to $64,430. number of aircraft that might need this on-condition action: jspears on DSK121TN23PROD with RULES ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 10 work-hours × $85 per hour = $850 (per rudder PCU load limiter) .................................................................... $50 $900 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 VerDate Sep<11>2014 16:05 Oct 20, 2022 Jkt 259001 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 PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 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.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), 
and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD 
was prompted by a report that some rudder power control unit (PCU) load 
limiters were found in service with the crimping missing from the end 
cap; therefore, the pilot command from the load limiter might not 
transmit correctly. This AD requires a one-time inspection of the 
rudder PCU load limiters for correct crimping of the end cap, and 
replacing any defective rudder PCU load limiter. For certain airplanes, 
this AD would also require repetitive testing of the rudder PCU load 
limiter for correct functioning, and applicable corrective actions. The 
FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective November 25, 2022.

3A, 601-3R, and 604 Variants) airplanes. The NPRM published in the 
Federal Register on June 9, 2022 (87 FR 35125). The NPRM was prompted 
by TCCA AD CF-2021-33, dated October 6, 2021, issued by Transport 
Canada Civil Aviation (TCCA), which is the aviation authority for 
Canada, (referred to after this as the MCAI).
    In the NPRM, the FAA proposed to require a one-time inspection of 
the rudder PCU load limiters for correct crimping of the end cap, and 
replacing any defective rudder PCU load limiter. For certain airplanes, 
the FAA also proposed to require repetitive testing of the rudder PCU 
load limiter for correct functioning, and applicable corrective 
actions. The FAA is issuing this AD to address defective rudder PCU 
load limiters, which could result in incorrect transmission of the 
pilot command, and loss of control of the rudder.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-0603.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from NetJets and one individual. The 
commenters noted the following typographical errors in the proposed AD:
     For serial numbers 5701 through 5988, the service bulletin 
reference should be ``605-27-010'' instead of ``650-27-010.''
     For serial numbers 6050 through 6158, the service bulletin 
reference should be ``650-27-003'' instead of ``605-27-003.''
    The FAA has corrected these errors in the Related Service 
Information section and in figure 1 to paragraph (g) of this AD.

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.

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.
