## Discrepancy

(CAN) DURING T/O ROLL, THE NR 2 ENGINE AUTOFEATHERED. THE T/O WAS ABORTED AND THE ACFT RETURNED TO THE RAMP.  TROUBLESHOOTING FOUND A FAULTY TORQUE SIGNAL CONDITIONER, WHICH WAS REPLACED BEFORE THE ACFT WAS RETURNED TO SERVICE. MFG RECOMMENDS THE SDR BE CLOSED ON THE BASIS OF THE FOLLOWING INFORMATION.
