## Discrepancy

THE LANDING GEAR WOULD NOT RETRACT AFTER TAKEOFF FROM CLE.  QRH WAS COMPLETED AND THE AIRCRAFT WAS RETURNED TO CLE WHERE IT LANDED WITHOUT INCIDENT.  TROUBLESHOOTING FOUND THE LANDING GEAR SELECTOR VALVE AT FAULT.  THE LG SELECTOR VALVE WAS REMOVED AND REPLACED IAW MM 32-31-51.  LEAK AND OPERATIONAL CHECKS WERE GOOD.  THE GROUND SPOILER INTERLOCK VALVE CABLE WAS ALSO REMOVED AND REPLACED IAW MM 27-62-51 DUE TO BINDING.
