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), CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15
(Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and
CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted
by reports of power control unit (PCU) rod end fractures due to pitting
corrosion. This AD requires revising the existing maintenance or
inspection program, as applicable, to incorporate new maintenance
tasks. This AD also requires detailed inspections of the elevator PCU
rod ends and applicable corrective actions. This AD also prohibits
using certain aircraft maintenance manual tasks. The FAA is issuing
this AD to address the unsafe condition on these products.
DATES: This AD is effective December 17, 2019.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of December 17,
2019.

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2018-29, dated November
2, 2018 (referred to after this 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), CL-600-2C10 (Regional Jet Series 700, 701 & 702),
CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series
900), and CL-600-2E25 (Regional Jet Series 1000) 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-2019-
0436.
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), CL-600-2C10
(Regional Jet Series 700, 701 & 702), 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 June 21, 2019 (84 FR 29108). The NPRM was prompted by reports of PCU
rod end fractures due to pitting corrosion. The NPRM proposed to
require revising the existing maintenance or inspection program, as
applicable, to incorporate new maintenance tasks. The NPRM also
proposed to require detailed inspections of the elevator PCU rod ends
and applicable corrective actions, and prohibit using certain aircraft
maintenance manual tasks.
The FAA is issuing this AD to address PCU rod end fractures due to
pitting corrosion, which, if not detected and corrected, could lead to
a disconnect between the PCU and the control surface, resulting in
potential loss of the control surface function or inadequate flutter
suppression. 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 comment
received. The commenter, Patrick Imperatrice, stated that he supports
the NPRM.
Conclusion
The FAA reviewed the relevant data, considered the comment
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.

Costs of Compliance
The FAA estimates that this AD affects 1,008 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
----------------------------------------------------------------------------------------------------------------
9 work-hours x $85 per hour = $765.............................. $0 $765 $771,120
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for revising the maintenance or inspection program.
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the FAA recognizes that this number may vary from operator to
operator. In the past, the FAA has estimated that this action takes 1
work-hour per airplane. Since operators incorporate maintenance or
inspection program changes for their affected fleet(s), the FAA has
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the FAA estimates the total cost per
operator to be $7,650 (90 work-hours x $85 per work-hour).
The FAA has received no definitive data that would enable the
agency to provide cost estimates for the on-condition actions specified
in this AD.
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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes and
associated appliances to the Director of the System Oversight Division.
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.
