Aircraft
While enroute; I heard a snap and some caution lights came on. The caution lights were the Number 1 ECU and the Number 1 fuel tank low caution light. I notice the torque on the Number 1 engine had fallen to 3.8 percent. The aircraft did not yaw when this event occurred. We ran the ECU checklist; but there was no improvement. I slowly retarded the Number 1 power lever to confirm that the engine was no longer producing power. It was not so we elected to shut down the Number 1 engine I suspected we had a TQ motor failure. After calling MTC; I found two more circuit breakers popped the Number 1 TQ cond; and the Number 1 auto temp controller.We ran some checklists and talked to the FO to decide what was going on. Once we concluded the Number 1 engine was not producing any power; we shut down that engine. Ran all the checklist. Declared an emergency. Notified company and made announcements to the people.
A DHC-8-100 Number 1 ECU and Fuel Tank Low caution lights illuminated along with the torque drop so the engine was shut down; the QRH completed; an emergency declared and the aircraft landed at its destination.
