## Discrepancy

DURING THE FLIGHT TO KSDF WITH THE AUTO PILOT ON MEL, THE FLIGHT CREW REPORTED THAT THE AILERONS LOCKED UP SEVERAL TIMES DURING FLIGHT.  THE AIRCRAFT LANDED WITHOUT INCIDENT IN KSDF.  MAINTENANCE INSPECTED THE AILERON CABLES AND FOUND NO DEFECTS.  THE AILERON ARTIFICIAL FEEL UNIT WAS REPLACED AS THE NEXT STEP IN THE FIM TASK TROUBLESHOOTING, AND DURING OPS CHECKS, THE LEFT AILERON DAMPER WAS FOUND TO BE LEAKING.  MAINTENANCE REPLACED BOTH AILERON DAMPERS AS A PRECAUTION.  THE AIRCRAFT WAS THEN TEST FLOWN WITH NO FURTHER DEFECTS NOTED AT THAT TIME.
