What this looks like in practice.
Past pattern: A KORD-based Global 6000 had a hydraulic leak after pushback. Mobile unit on the ramp from KGRB within 4 hours, hydraulic actuator isolated and replaced, leak source confirmed, system pressurized and signed off. Crew departed same evening with 5-hour delay vs. potential ferry-out and 24-hour OEM wait.
