Narrative:
Our falcon 20 was parked and chocked opposing a beech king air on the ZZZ ramp. The parking brake was set. 3 passenger boarded, and the APU started. FBO personnel removed the chocks and the falcon 20 started rolling forward with the parking brake on. Crew attempted motoring an engine to get hydraulic pressure, but were unable to attain any braking before the falcon 20 collided with the king air. Damage was minor, but could have been prevented if chocks had been replaced promptly when the aircraft started rolling. Supplemental information from acn 350184: after previous day's ramp event, our director of maintenance confirmed the airworthiness of the aircraft. Unable to duplicate the prior situation, including parking brake and annunciator failure. Per our MEL, the aircraft was flown to our base after the necessary maintenance documentation. Supplemental information from acn 350182: suspect intermittent 3-WAY hydraulic valve.
