## Discrepancy

WHILE BEGINNING THE CLIMBOUT, THE CREW RECEIVED A PACK OVER PRESSURE AND PACK FAIL MESSAGE FOR BOTH PACKS.  THE CAPTAIN THEN DECIDED TO EXECUTE A RETURN TO THE FIELD.  OUTSTATION MAINTENANCE INSPECTED AND PERFORMED OPERATIONAL CHECKS IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 21-00-00 AND FOUND THAT BOTH PACKS WORKED NORMALLY.  AFTER THESE POSITIVE OPERATIONAL CHECKS, THE AIRCRAFT WAS RELEASED FOR SERVICE.
