## Discrepancy

AIR TURNBACK FLIGHT 7757 AT MAF:  WHEN CREW SELECTED GEAR UP, THE MAIN GEAR WOULD NOT RETRACT AND RECEIVED A LOW PRESSURE LIGHT ON THE GREEN HYDRAULIC SYSTEM.  THE NR 2 ACW SYSTEM FAILED.  CREW ELECTED TO RETURN TO MAF.  INSPECTED C/B AND FOUND THE GREEN SYSTEM HYD PUMP C/B POPPED.  RESET C/B RAN ENGINES AND LOW PRESSURE LIGHT WAS EXTINGUISHED ON THE GREEN SYSTEM, PRESSURE WAS 3000 PSI.  TAXI ACFT AND CHECK BRAKES FROM THE PILOTS, F/OS, AND HAND/PARKING BREAK.  SYSTEM CHECK GOOD AND WORKED NORMALLY.  AIRCRAFT WAS RETURNED TO SERVICE.
