Jazz DH8A at Val'd Or on Nov 27th 2013, rejected takeoff, then engine shut down in flight

A Jazz de Havilland Dash 8-100, registration C-FGRY performing flight QK-8752 from Val d'Or,QC to Montreal,QC (Canada) with 26 people on board, was cleared for takeoff, the crew applied take off power, while the engines accelerated the torque indication for the right hand engine (PW120A) dropped to zero for about 5 seconds. The crew rejected takeoff at about 20-30 knots. The crew subsequently performed three engine run ups, the fault did not re-occur. The crew therefore decided to depart. Following an uneventful takeoff run the aircraft climbed through 700 feet AGL when the right hand propeller auto-feathered. The crew declared emergency, shut the engine down and returned to Val d'Or for a safe landing.

The Canadian TSB reported that maintenance replaced the right hand engine, the right hand propeller assembly and the #1 torque signal control unit. A wiring check was performed without any anomalies found. Engine runs revealed no faults and the aircraft was returned to service. Tests on the replaced engine and propeller assembly showed no faults.
