## Discrepancy

FOLLOWING TAKEOFF, THE CREW NOTED THAT THE LEFT HYDRAULIC SYSTEM QUANTITY DROPPED TO ZERO.  NO MENTION OF EITHER SYSTEM PRESSURE INDICATIONS.  COM PROCEDURES WERE COMPLIED WITH AND THE FLIGHT CONTINUED TO SCHEDULED DESTINATION.  LANDING AT DTW WAS UNEVENTFUL AND MAINTENANCE FOUND A HYDRAULIC LINE FROM THE FORWARD SOLENOID VALVE SPLIT OPEN AND SPRAYING FLUID.  THE LINE, ENGINE DRIVEN PUMP, AND FILTERS WERE ALL REPLACED.  THE SYSTEM WAS RESERVICED, LEAK AND PRESSURE CHECKED, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
