## Discrepancy

DURING CRUISE, THE FLIGHT CREW RECEIVED A, LT HYD ENG PUMP FAIL, CAS MESSAGE.  THIS WAS A REPEAT PUMP FAIL FOLLOWING THE PREVIOUS FLIGHT AND AFTER THE ACFT WAS RELEASED FROM MAINTENANCE FOR A LT HYDRAULIC LEAK & PUMP FAIL MESSAGE. FLIGHT CREW ELECTED TO DIVERT AND LANDED UNEVENTFULLY.  MAINTENANCE TECHS REPLACED THE FAULTY LT ENGINE DRIVEN HYDRAULIC PUMP, PN 51160-06, AND CASE DRAIN MANIFOLD, PN 945175-1.  LEAK AND OPS CHECKS WERE NORMAL.  THE ACFT WAS RETURNED TO SERVICE.
