Federal Register Volume 82, Issue 69 (April 12, 2017)

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-102, -103, and -106 airplanes; and Model DHC-8-200 and DHC-8-300 series airplanes. This AD was prompted by reports of incorrect installation of the auto-ignition system due to crossed wires at one of the splices in the auto-relight system. This AD requires inspecting the auto-ignition system for correct wiring, and doing corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

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 DHC-8-102, -103, and -106 airplanes; and Model DHC-8-200 and DHC-
8-300 series airplanes. The NPRM published in the Federal Register on 
October 26, 2016 (81 FR 74360) (``the NPRM''). The NPRM was prompted by 
reports of incorrect installation of the auto-ignition system due to 
crossed wires at one of the splices in the auto-relight system. The 
NPRM proposed to require inspecting the auto-ignition system for 
correct wiring, and doing corrective actions if necessary. We are 
issuing this AD to detect and correct incorrect wiring of the auto-
ignition system, which could result in inability to restart the engine 
in flight and consequent reduced controllability of the airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-36, dated November 19, 2013 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Bombardier, Inc., Model DHC-8-
102, -103, and -106 airplanes; and Model DHC-8-200 and DHC-8-300 series 
airplanes. The MCAI states:

    There have been reports of incorrect installation of the auto-
ignition system introduced by MS [ModSum] 8Q100813 of SB [Service 
Bulletin] 8-74-02, where wires crossed at one of the splices in the 
auto-relight system. The incorrect wire installation may result in 
the inability to achieve an in-flight engine relight when the 
ignition switch is selected in the AUTO position.
    Bombardier has issued SB 8-74-05 to introduce an inspection to 
check for correct wiring connection and rectification as required. 
This [Canadian] AD mandates incorporation of Bombardier SB 8-74-05.

    Corrective actions include reconnecting any incorrect wiring of the 
auto-ignition system and performing a functional test. 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-2016-9299.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. The Air Line Pilots 
Association, International (ALPA) supported the NPRM.

Conclusion

    We reviewed the relevant data, considered the comment received, 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
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 8-74-05, Revision B, dated 
April 14, 2014. This service information describes procedures for 
inspecting the auto-ignition system for correct wiring, and doing 
corrective actions that include rewiring if needed, followed by a 
functional test of the auto-ignition system. 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 88 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
               Action                        Labor cost           Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Inspection..........................  1 work-hour x $85 per                $0              $85           $7,480
                                       hour = $85.
----------------------------------------------------------------------------------------------------------------


[[Page 17539]]

    In addition, we estimate that any necessary corrective actions will 
take about 2 work-hours, for a cost of $170 per product. We have no way 
of determining the number of aircraft that might need these actions.

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.
