RIN 2120-AA64


Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier Inc. Model DHC-8-102, -103, and -106 airplanes; DHC-
8-200 series airplanes; and Model DHC-8-300 series airplanes. This 
proposed 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 proposed AD would require inspecting the 
auto-ignition system for correct wiring, and doing corrective actions 
if necessary. We are proposing 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.

DATES: We must receive comments on this proposed AD by December 12, 
2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    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; DHC-8-200 series airplanes; and Model 
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 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.

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.

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 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 88 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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.
----------------------------------------------------------------------------------------------------------------

    In addition, we estimate that any necessary corrective actions 
would 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 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.
