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-600-2B19 (Regional Jet Series 100 &
440) airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701 & 702)
airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and
Model CL-600-2D24 (Regional Jet Series 900) airplanes; and all
Bombardier, Inc., Model CL-600-2C11 (Regional Jet Series 550)
airplanes. This AD was prompted by reports of fractured rudder primary
feel unit shafts; a subsequent investigation determined that the
fractures in the shafts are consistent with fatigue damage. This AD
requires replacement of the rudder primary feel unit shaft. The FAA is
issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective June 10, 2020.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of June 10,
2020.

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2019-42, dated November
8, 2019 (also referred to as the Mandatory Continuing Airworthiness
Information, or ``the MCAI''), to correct an unsafe condition for
certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 &
440) airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701 & 702)
airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and
Model CL-600-2D24 (Regional Jet Series 900) airplanes; and all
Bombardier, Inc., Model CL-600-2C11 (Regional Jet Series 550)
airplanes. You may examine the MCAI in the AD docket on the internet at
https://www.regulations.gov by searching for and locating Docket No.
FAA-2020-0092.
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-600-2B19 (Regional Jet Series 100 & 440) airplanes,
Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, Model
CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL-600-2D24
(Regional Jet Series 900) airplanes; and all Bombardier, Inc., Model
CL-600-2C11 (Regional Jet Series 550) airplanes. The NPRM published in
the Federal Register on February 18, 2020 (85 FR 8768). The NPRM was
prompted by reports of fractured rudder primary feel unit shafts; a
subsequent investigation determined that the fractures in the shafts
are consistent with fatigue damage. The NPRM proposed to require
replacement of the rudder primary feel unit shaft. The FAA is issuing
this AD to address fractures of the rudder primary feel unit shaft,
which could result in a loss of feel in the yaw axis and thereby impact
the controllability of the airplane. See the MCAI for additional
background information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA has considered the comments
received. The Air Line Pilots Association, International (ALPA) and
Jacob Yepiz stated support for the NPRM.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule as proposed, except for minor
editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Service Bulletin 601R-27-166, dated April 5,
2019; and Service Bulletin 670BA-27-075, dated April 5, 2019. This
service information describes procedures for replacing the rudder
primary feel unit shaft that has part number 600-90251-1 with a new
shaft. These documents are distinct since they apply to different
airplane models. 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 1,002 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
[[Page 26843]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
18 work-hours x $85 per hour = $1,530........................ $158 $1,688 $1,691,376
----------------------------------------------------------------------------------------------------------------
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 our 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,
(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.
