## Discrepancy

DURING THE FLIGHT TO PIT, A MAIN HYDRAULIC FAIL WARNING MESSAGE WAS NOTED BY THE CREW.  THE FLIGHT CREW DECLARED AN EMERGENCY, AND CONTINUED INTO PIT.  THE AIRCRAFT LANDED IN PIT WITHOUT ANY FURTHER PROBLEMS.  MAINTENANCE INSPECTED AND REPLACED THE MAIN HYDRAULIC PUMP IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 29-00-00.  OPERATION AND LEAK CHECKS WERE COMPLETED, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
