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.
