## Discrepancy

GEG- ON FLIGHT 2359 AFTER LIFTOFF NOSE GEAR RETRACTED NORMALLY BUT BOTH MAIN GEAR FAILED TO RETRACT.  CREW WENT THROUGH CHECKLIST.  GEAR CYCLED AGAIN.  NOSE GEAR WORKED FINE, BUT STILL RECIEVED YELLOW AND RED ON BOTH MAIN GEAR ON GEAR RETRACTION.  FLIGHT RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  REMOVED AND REPLACED MAIN LANDING GEAR SELECTOR VALVE.  OPERATIONAL CHECKS GOOD.  AIRCRAFT RETURNED TO SERVICE.
