## Discrepancy

CLE FLIGHT 2117 THE CREW REPORTED THE LANDING GEAR SELECT LEVER REQUIRED THE DOWNLOCK RELEASE BUTTON TO BE PRESSED TO RETRACT THE GEAR.  MAINTENANCE REPLACED THE LANDING GEAR SELECT LEVER CONTROL ASSEMBLY.  ALSO REPLACED RELAYS KOO24, KOO25, AND KO453.  OPERATIONAL CHECKS WERE GOOD.  THE AIRCRAFT WAS RELEASED FOR SERVICE.
