## Discrepancy

APPROXIMATELY 5 MINS AFTER DEPARTURE, WE HEARD A LOUD HUMMING SOUND COMING FROM THE REAR OF THE AIRPLANE. WE THEN GOT A HYD PUMP FAIL A MESSAGE, FOLLOWED BY HYD VOLUME LOW A. WE RAN THE QRH AND DURING APPROACH WE GOT A GND SPOILER FAULT MESSAGE AS WELL. ON LANDING THE GROUND SPOILERS WERE STUCK IN THE DEPLOYED POSITION. AFTER SHUTTING DOWN, I NOTICED A POOL OF FLUID UNDER THE LEFT ENGINE, AND FLUID DRIPPING FROM THE LEFT COWLING. REMOVED AND REPLACED LEFT ENGINE HYDRAULIC PUMP REF: CESSNA MODEL 700 MAINTENANCE MANUAL (REV14) 29-10-05 (REV 2)
