Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2018-17, dated June 29, 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) airplanes. The MCAI states:

    Bombardier has received reports from the manufacturer of its 
Angle of Attack (AOA) transducers indicating that there is a 
possibility of excessive error in the signal generated by the AOA 
Transducer. It is possible that this error may not be detected by 
the stall protection computer, which could lead to late stall 
protection system activation and potentially result in the loss of 
control of the aeroplane. The error could be a result of incorrect 
assembly or/and internal wear in the AOA Transducer.
    This [Canadian] AD mandates the modification or replacement of 
the AOA transducers in order to prevent late activation of the stick 
pusher in the stall protection 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-2018-
1008.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Service Bulletin 601R-27-165, dated December 
20, 2016. This service information describes procedures for replacing 
certain AOA transducers with new or modified AOA transducers. 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

    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 of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop

[[Page 63595]]

on other products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Differences Between This Proposed AD and the MCAI

    The applicability of the MCAI is limited to Bombardier, Inc., Model 
CL-600-2B19 (Regional Jet Series 100 & 440) airplanes having serial 
number 7003 through 7067 inclusive and 7069 through 7891 inclusive, and 
equipped with AOA transducers having part number (P/N) 45-150-340, 
C16258AA, or C16258AB. However, the applicability of this proposed AD 
specifies Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 
& 440) airplanes having serial number 7003 through 7067 inclusive and 
7069 through 7891 inclusive. Airplanes having serial number 7003 
through 7067 inclusive and 7069 through 7891 inclusive that are not 
equipped with the affected parts must comply with the parts 
installation prohibition specified in paragraph (h) of this proposed 
AD.

Costs of Compliance

    We estimate that this proposed AD affects 525 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
            Labor cost                    Parts cost          Cost per product        Cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
5 work-hours x $85 per hour = $425  Up to $6,800.........  Up to $7,225.........  Up to $3,793,125
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all 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 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.
    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.
    This proposed 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

    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.
