## Discrepancy

SHIP 9521 - THE CREW DECLARED AN EMERGENCY DURING THE APPROACH FOR LANDING IN ATL DUE TO THE LOSS OF LEFT HYDRAULIC SYSTEM FLUID QUANTITY. CORRECTIVE ACTION: MAINTENANCE FOUND THE SOURCE OF THE LEAK AND REPLACED THE DAMAGED SECTION OF A HYDRAULIC LINE NEAR THE LEFT THRUST REVERSER CONTROL VALVE. THE LEAK CHECK AND OPERATIONAL CHECK WERE GOOD. THE AIRCRAFT HAS RETURNED TO SERVICE. (LP #8186722)
