## Discrepancy

THE AIRCRAFT RETURNED TO THE GATE, DUE TO AN ANGLE OF ATTACK WARNING MESSAGE.  OUTSTATION MAINTENANCE INSPECTED AND APPROVED THE AIRCRAFT FOR A FERRY FLIGHT TO PIT, TO ACCOMPLISH REPAIRS.  THE FERRY FLIGHT WAS CARRIED OUT WITHOUT ANY PROBLEMS.  PIT MAINTENANCE INSPECTED AND REPLACED THE LEFT HAND ANGLE OF ATTACK SENSOR, IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 27-33-01.  OPERATIONAL CHECKS WERE COMPLETED, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
