## Discrepancy

SHORTLY AFTER TAKEOFF OF FLIGHT, THE CREW WAS UNABLE TO RETRACT THE GEAR.  THE CREW PERFORMED AN AIR-TURN-BACK.  MECHANIC INSPECTED THE SYSTEM AND REPLACED THE MLG HANDLE/SWITCH BUT OPS CHECKS WERE STILL BAD.  MECHANIC REPLACED THE GROUND SERVICE VALVE AND PERFORMED A GEAR SWING, WITH NO FURTHER DISCREPANCIES NOTED, AC WAS RETURNED TO SERVICE. (K)
