## Discrepancy

CLE FLIGHT 3750 THE CREW REPORTED THE LEFT MAIN GEAR WOULD NOT RETRACT.  THE INDICATION WAS UNLOCK LIGHT ON THE LEFT GEAR.  THE AIRCRAFT RETURNED TO CLEVELAND AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED THE LEFT GEAR UPLOCK BOX ASSEMBLY.  OPERATIONAL CHECKS WERE GOOD.  THE AIRCRAFT WAS RELEASED FOR SERVICE.
