HAD THIS OCCURRED AT TAKEOFF DURING ROTATION, CONTROL OF ACFT WOULD BE DIFFICULT AS NTS SYS WILL NOT SENSE A FAILURE WITH 300 POUNDS TORQUE AND THE ENG IS PRODUCING MORE DRAG THAN THRUST AND WILL NOT AUTOFEATHER. THIS SITUATION CAN BE ISOLATED BY TURNING OFF AUTO TORQUE AND EGT FUNCTIONS OF THE COMPUTER.
