## Discrepancy

DURING A TRAINING FLIGHT 25 MILES EAST OF AIRPORT, AT 5000 FT, THE ELEVATOR TRIM CONTROL BOUND AND JAMMED UP. AFTER ATTEMPTS TO FREE UP THE TRIM WERE UNSUCCESSFUL, THE CREW DECLARED AN EMERGENCY WITH CONTROL AND LANDED ON WITHOUT INCIDENT.  MX PERFORMED A VISUAL INSPECTION OF THE ELEVATOR TRIM CONTROL CABLES ROUTING, NO DEFECTS WERE NOTED. MX LUBRICATED THE ELEVATOR TRIM ACTUATOR AND VERIFIED PROPER CABLE TENSIONS. NO DEFECTS WERE NOTED AFTER PERFORMING OPERATIONAL AND FUNCTIONAL CHECKS OF THE ELEVATOR TRIM SYSTEM. THE AC WAS RELEASED FOR THE PURPOSES OF A TEST FLIGHT. MANUAL AND ELECTRICAL OPERATION OF THE ELEVATOR TRIM DURING THE TEST FLIGHT WAS FOUND TO BE NORMAL WITH NO FURTHER DISCREPANCIES NOTED. THE AC WAS APPROVED FOR RETURN TO SERVICE.
