Gulfstream 200 flight crew reported a hydraulic failure inflight at FL380.
Synopsis
Gulfstream 200 flight crew reported a hydraulic failure inflight at FL380.
Narrative
While in Cruise at FL380; during final hour of flight before beginning descent into ZZZ1 via assigned STAR. Aircraft displayed loss of hydraulic quantity; followed by loss of hydraulic pressure CAS messages while in flight. Auxiliary hydraulic loss of pressure occurred soon after; resulting in a complete loss of Right Hydraulic system. System controls Gear extension/Q feel/Normal Braking/Right Thrust Reverser/Inboard Airbrakes/Nose wheel Steering/Kreugers/and Stick pusher.Decision was made to divert from ZZZ1 to ZZZ in favor of longer and wider runways. Coordinated with ATC; [requested priority handling]; and further coordinated with company Operations; Maintenance; and Chief Pilot.Proceeded to ZZZ for landing on Runway XXL; landed safely and on centerline. Required to be towed off runway due to loss of steering and normal braking. Coordinated with Ground Control; Authorities; Fire/rescue; and FBO to meet us on the ground and tow us to the FBO.Pilots initially briefed procedures when initial CAS messages began to appear and briefed passengers once decision to divert was made. 2 crew; and 2 passengers totally 4 souls on board. No injuries or damage to plane was incurred from the event.
Second reporter narrative
In cruise about from ZZZ2- ZZZ1 with 2 passengers aboard; 1 hour left in flight; and noticed right hydraulic levels and pressure fluctuating. Right hydraulic system eventually failed and [ATC was advised] with a request to divert to ZZZ for the longest runway. ATC assisted in giving us direct and set us up for a straight in visual for Runway XXL at ZZZ. Hydraulic failure caused lack of braking ability as well as loss of nose wheel steering which caused us to stop on the runway; thus closing the runway; until we could be hooked up and towed off via tug back to the FBO ramp.
