## Discrepancy

(CAN) ON THE CLIMBOUT THE CREW OBSERVED ABNORMAL TORQUE AND ITT INDICATIONS. AS A PRECAUTION, THE CREW ELECTED TO SHUTDOWN THE LT ENGINE.  THE ACFT RETURNED WHERE AN UNEVENTFUL LANDING WAS CARRIED OUT.  FLIGHT CREW REPORTED NOISE CAN BE HEARD COMING FROM THE ACCESSORY GEARBOX WHEN ROTATED.  MAINTENANCE PERSONNEL WILL EXAMINE THE ACFT TO DETERMINE THE CAUSE OF THE ABNORMAL INDICATIONS.
