## Discrepancy

DURING CLIMBOUT, THE FLIGHT CREW RETRACTED THE LANDING GEAR AND RECEIVED MULTIPLE CAS MESSAGES INDICATING THAT MAIN HYDRAULIC POWER WAS LOST.  THE FLIGHT CREW REFERENCED THE QRH AND DIVERTED TO TOL.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE MAIN HYDRAULIC AC PUMP ASSEMBLY IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 29-11-00.  FUNCTIONAL CHECKS WERE COMPLETED AND THE AIRCRAFT RETURNED TO SERVICE.
