Aircraft
While on a visual approach; we experienced a total loss of Hydraulic power. On the downwind leg the landing gear was lowered and immediately after all landing gear had normal down indications (three green lights) the amber HYDRAULIC VOLUME LOW CAS message appeared and the hydraulic fluid quantity indicated a low condition of only 90 cubic inches. The downwind leg was extended and the emergency checklist was accomplished. It was determined that a safe landing could be made and the landing was executed with no incident and emergency braking was applied to stop the aircraft. This was an unforeseen and unavoidable rare system failure. Our training proved effective and resulted in the safe completion of this event.
Hydraulic Volume Low CAS message illuminated on a left downwind after gear was selected down. Positive ID of gear down was established with 3 illuminated green lights and throttle/flap position. Extended downwind leg to run appropriate checklist. Landed successful.
