## Discrepancy

AFTER TAKEOFF,  CREW RECEIVED A NR 2 HYD PUMP CAUTION LIGHT WHEN THEY ATTEMPTED TO RETRACT THE GEAR.  THE GEAR DID NOT RETRACT AND THE NR 2 MAIN PRESSURE WAS AT 0.  THE STANDBY PRESSURE WAS GOOD.  THE CREW MADE AN UNSCHEDULED LANDING AND RETURNED TO THE GATE.  THE GROUND MX CREW BLED THE NR 2 HYD SYS AND FOUND AIR IN THE SYS.  THEY CYCLED THE GEAR AND SERVICED THE SYS.  ALL OPS AND LEAK CHECKS WERE SATISFACTORY.
