SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-30, dated September 21, 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-
2E25 (Regional Jet Series 1000) airplanes. The MCAI states:

    It was discovered during an inspection that circuit breakers 
installed on the cockpit circuit breaker panels may have cracks in 
the plastic casing. The damage was found on a Bombardier CL-600-2E25 
production aeroplane following a routine functional test procedure. 
A fleet inspection also found similar damage on the in-service 
aeroplanes.
    Cracked circuit breakers can allow moisture ingress and damage 
the interior of the circuit breaker and circuit breaker panels 
resulting in a malfunction of the affected circuit breaker and the 
potential loss of power to multiple airplane systems.

    Corrective actions include inspecting the circuit breakers for any 
cracks or signs of damage (including small white lines on the casing), 
replacing any cracked or damaged circuit breakers, and installing a 
circuit breaker bushing assembly. You may examine the MCAI on the 
Internet at http://www.regulations.gov by searching for and locating 
Docket No. FAA-2017-0252.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc., has issued Service Bulletin 670BA-24-037, 
Revision A, dated July 11, 2016. The service information describes a 
detailed visual inspection of each circuit breaker for any cracks or 
signs of damage, replacement of damaged circuit breakers, and 
installation of a circuit breaker bushing assembly. 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 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 of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

[[Page 19180]]

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2017-0252; Directorate 
Identifier 2016-NM-187-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. If an 
affected airplane is imported and placed on the U.S. Register in the 
future, we provide the following cost estimates to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                 Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
Inspection....................................  3 work-hours x $85 per hour =                 $0            $255
                                                 $255.
Installation of bushing assembly..............  43 work-hours x $85 per hour =                 0           3,655
                                                 $3,655.
----------------------------------------------------------------------------------------------------------------

    In addition, we estimate that it will take about 1 work-hour for 
each circuit breaker requiring replacement and will require parts 
costing $0, for a cost of $85 per circuit breaker. We have no way of 
determining the number of aircraft that might need this action.

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 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. 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.

Bushing Assembly

    At the applicable time specified in paragraph (h)(1) or (h)(2) 
of this AD: Install a cockpit breaker bushing assembly, and do a 
detailed visual inspection of each circuit breaker for cracks or 
damage, in accordance with ``Part B--Installation of the Cockpit 
Panel Circuit Breakers Bushings assembly,'' of the Accomplishment 
Instructions of Bombardier Service Bulletin 670BA-24-037, Revision 
A, dated July 11, 2016. Replace any cracked or damaged circuit 
breakers before further flight, in accordance with the 
Accomplishment Instructions of Bombardier Service Bulletin 670BA-24-
037, Revision A, dated July 11, 2016. Installing the cockpit panel 
circuit breaker bushing assembly is acceptable for compliance with 
the requirements of paragraph (g) of this AD.
    (1) For airplanes that have accumulated less than 10,000 total 
flight hours as of the effective date of this AD: Before the 
accumulation of 12,600 total flight hours.
    (2) For airplanes that have accumulated 10,000 or more total 
flight hours as of the effective date of this AD: Within 2,000 
flight hours after the effective date of this AD.
