## Discrepancy

(CAN) JOURNEY LOG:  TAKEOFF ABORTED DUE TO ENGINE NR 2 TORQUE NOT PASSING 60 PERCENT. ON SHUTDOWN PROP NR 2 WOULD NOT FEATHER. AIRCRAFT RETURNED TO GATE DUE TO NR 2 ENGINE SLUGGISH TO ACCELERATE, PROP FOUND NOT TO BE FEATHERING AUTOMATICALLY OR MANUALLY.  INSPECTION ON PROP HUB ASSEMBLY, PCU REPLACED AS PER MM, ENGINE RUNS CARRIED OUT, OK. REPLACEMENT OF THE PCU WAS THE FINAL FIX.
