14 CFR Part 39

[Docket No. FAA-2017-1025; Product Identifier 2017-NM-137-AD; Amendment 
39-19199; AD 2018-04-04]

Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc., Model 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 several incidents of electrical shorting and sparks 
caused by de-icing fluid leaks between flight deck windshields and side 
windows. This AD requires water spray tests and general visual 
inspections for water in the flight deck compartment, and water removal 
and sealant application if necessary. We are issuing this AD to address 
the unsafe condition on these products.

DATES: This AD is effective March 30, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 30, 
2018.

SUPPLEMENTARY INFORMATION: 

Discussion

    We 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-600-2C10 (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 November 17, 2017 (82 FR 54304) (``the NPRM'').
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2017-28, dated August 23, 2017 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc., Model CL-600-2C10 
(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 MCAI states:

    Several incidents of electrical shorting and sparks have been 
reported in the cockpit of CL-600-2C10 and CL-600-2D24 aeroplanes. 
De-icing fluid can leak between the windshields and side windows, 
leading to possible damage to the cockpit floodlight wires and 
electrical connections. If not corrected, this condition may result 
in a flight compartment fire.
    This [Canadian] AD is issued to mandate a water spray test and 
[general visual] inspection for evidence of fluid ingress into the 
flight compartment. It also provides mandatory instructions for 
sealant application if required.

    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-
1025.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and

[[Page 7973]]

     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, Inc., has issued Service Bulletin 670BA-56-003, 
Revision A, dated April 13, 2016. This service information describes 
procedures for doing water spray tests on the flight deck windows, 
doing general visual inspections for water in the flight deck 
compartment, removing water, and applying sealant to the flight deck 
windows. 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

    We estimate that this AD affects 543 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

Spray tests and inspections...........  2 work-hours x $85 per                $0            $170         $92,310
                                         hour = $170.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary water removal 
and sealant application that would be required based on the results of 
the inspection. We have no way of determining the number of airplanes 
that might need this water removal and sealant application:

----------------------------------------------------------------------------------------------------------------

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 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 to 
the Director of the System Oversight Division.

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.
