Narrative:

As we finished our before takeoff checklist we proceeded with a standard takeoff; power was set; gauges were checked and we proceeded with our rotation. As soon as positive rate gear up we heard loud noise as the gear was being retracted; then we had cas message for hydraulic a low volume as well as rapidly decreasing. At 400 ft and within seconds of this occurring we lowered the landing gear. We proceeded with the checklist called approach and informed them of the situation and request return to the station. We climbed to 2;000 ft and it was an unrestricted visibility night with no cloud cover. We were cleared to land on runway 10. The checklist was followed for a hydraulic failure on the a system with no hydraulic volume. Since the primary breaks did not work nor were full flaps available or spoilers; according to the checklist; we proceeded using the emergency brakes which slowed down the aircraft to more or less 60 KTS. As we realized the runway was coming to an end we turned into the grass area to help stop the aircraft. We hit the PAPI light system for runway 28 which was not illuminated. Once the aircraft came to a complete stop we checked on the passengers; as no one was hurt and we proceed towards the exit of the aircraft.

Title: CE750 Captain experiences Hydraulic System A failure as the gear is retracted on departure. The gear is extended before complete system failure and the flight returns to the departure airport after complying with checklist procedures. Flaps and spoilers are inoperative with the loss of the A System along with normal brakes. The crew is unable to stop on the 11;000 FT plus runway using emergency brakes and a runway excursion occurs.
