Applicability*9

This AD applies to Bombardier, Inc., airplanes identified in paragraphs (c) (1), (c) (2), and (c) (3) of this AD, certificated in any category, serial numbers 003 through 672 inclusive, on which Bombardier ModSum 8Q100813 or Bombardier Service Bulletin 8-74-02 is incorporated. (1) Model DHC-8-102, -103, and -106 airplanes. (2) Model DHC-8-201 and -202 airplanes. (3) Model DHC-8-301, -311, and -315 airplanes.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 2,000 flight hours or 12 months after the effective date of 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.

Unsafe condition

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. 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.

Affected ADs

None.
