Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-38, effective December 12, 2016 (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-
2B16 (CL-604 Variant) airplanes. The MCAI states:

    The [Canadian] AD CF-2013-22 [which corresponds to FAA AD 2014-
16-06, Amendment 39-17930 (79 FR 48972, August 19, 2014)] was issued 
on 12 August 2013 to mandate the introduction of an emergency 
procedure to the Aeroplane Flight Manual to address the uncommanded 
rudder movement.
    Since the original issue of [Canadian] AD CF-2013-22, Bombardier 
Aerospace has developed a wiring modification for the yaw damper 
control system to prevent uncommanded movement of the rudder.
    This [Canadian] AD mandates the incorporation of Service 
Bulletins (SB) 604-22-007 and 605-22-002 * * * *.

    This proposed AD would require modification of the wiring for the 
yaw damper control system. You may examine the MCAI in the AD docket on 
the Internet at http://www.regulations.gov by searching for and 
locating Docket No. FAA-2017-0626.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc., issued Service Bulletin 604-22-007, Revision 01, 
dated July 25, 2016; and Service Bulletin 605-22-002, Revision 01, 
dated July 25, 2016. The service information describes procedures for 
modifying the wiring harness for the yaw damper control system. These 
documents are distinct since 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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified

[[Page 29015]]

of the unsafe condition described in the MCAI and service information 
referenced above. We are proposing this AD because we evaluated all 
pertinent information and determined an unsafe condition exists and is 
likely to exist or develop on other products of the same type design.

Costs of Compliance

    We estimate that this proposed AD affects 120 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
            Action                  Labor cost         Parts cost      Cost per product   Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Modification..................  50 work-hours x    Up to $478.......  Up to $4,728......  Up to $567,360
                                 $85 per hour =
                                 $4,250.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all 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.
    We are 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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.

reference, Safety.
