Abstract
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.

Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
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.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of November 25,
2022.

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 <a href="http://regulations.gov">regulations.gov</a> 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:
<bullet> For serial numbers 5701 through 5988, the service bulletin
reference should be ``605-27-010'' instead of ``650-27-010.''
<bullet> 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.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following service information.
<bullet> Bombardier Service Bulletin 604-27-039, Revision 01, dated
April 6, 2021.
<bullet> Bombardier Service Bulletin 600-0776, dated December 7,
2020.
<bullet> 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.
<bullet> Bombardier Service Bulletin 605-27-010, dated December 7,
2020.
<bullet> 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
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 2 work-hours x $85 per hour = $0 Up to $170.............. Up to $64,430.
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 number of aircraft
that might need this on-condition action:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
10 work-hours x $85 per hour = $850 $50 $900
(per rudder PCU load limiter)........
------------------------------------------------------------------------
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.
