Incident

The takeoff was rejected when the left engine torque indication was noted to be 13% below target torque. The subsequent investigation found that a fuel control unit drive shaft seal failure had allowed fuel to wash the lubrication from the shaft bearings which then failed. The drive shaft and spacer were badly worn and had caused a restriction to the governor flyweights which had signalled the lower torque during takeoff.
