    this AD, whichever occurs first: Inspect the auto-ignition system  for
    correct wiring and do all applicable corrective actions, in accordance
    with  the Accomplishment Instructions of Bombardier Service Bulletin 8
    -74-05, Revision B,  dated April 14, 2014.  All applicable  corrective
    actions must be done before further flight.

(h) CREDIT FOR PREVIOUS ACTIONS

    This paragraph provides credit  for the actions required  by paragraph
    (g) of this AD, if  those actions were performed before  the effective
    date of this AD using Bombardier Service Bulletin 8-74-05,  dated July
    12, 2013; or Revision A, dated January 27, 2014.

    York ACO,  send it to the attention  of the person identified in para-
    graph (j) (2) of this AD. Before using any approved AMOC,  notify your
    appropriate principal inspector, or lacking a principal inspector, the
    manager  of  the  local  flight standards district  office/certificate
    holding district office.

(2) Contacting the Manufacturer:  For any requirement in this AD to obtain
    corrective actions from a manufacturer the action must be accomplished
    using a method approved by the Manager, New York ACO, ANE-170, FAA; or

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

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

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.
