## Discrepancy

(CAN) THE ELEVATOR SERVO MOTOR WAS RECEIVED IN REPAIRED CONDITION AND INSTALLED, AFTER 3.2 HRS THE CREW WAS CARRYING OUT THE PREFLIGHT FLIGHT CONTROL CHECK AND A LOUD GRINDING NOISE WAS COMING FROM THE AFT PART OF THE ACFT.  MAINTENANCE REMOVED THE SERVO MOTOR AND REPLACED WITH A SERVICEABLE UNIT.
