## Discrepancy

STL TO DSM - DURING CLIMB-OUT OF STL, FLIGHT CREW RECEIVED FLAP FAIL EICAS MESSAGE.  CAPTAIN RAN QRH AND IT WAS DECIDED TO RETURN TO STL.  THE AIRCRAFT LANDED WITHOUT INCIDENT IN STL AND WAS TURNED OVER TO MAINTENANCE.  MAINTENANCE CHECKED THE CMC MESSAGES AND FOUND A CMC MESSAGE FOR FLAP JAMMING.  THE FAULT WAS TRACED TO THE RT FLAP TRANSMISSION BRAKE AND THE TRANSMISSION BRAKE WAS REPLACED.  THE FLAPS WERE RIGGED AFTER REPLACEMENT OF THE TRANSMISSION BRAKE AND THE FLAP SYSTEM CHECKED GOOD.
