## Discrepancy

FLIGHT 4168 WAS CLIMBING THROUGH FL150 AND THE RIGHT HAND ENGINE TORQUE DROPPED TO 50 PERCENT AND STAYED THERE.  THE CREW RADIOED MAINTENANCE CONTROL, DECLARED AN EMERGENCY, AND RETURNED TO THE FIELD.  MAINTENANCE INSPECTED AND REPLACED THE RIGHT HAND ENGINE TORQUE PROBE IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 77-11-01.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
