## Discrepancy

AFTER TAKEOFF THE CREW RECEIVED A FLAP FAIL MESSAGE ON EICAS.  RAN THROUGH THE APPROPRIATE CHECK LISTS AND RETURNED TO IAH AND LANDED WITHOUT INCIDENT.  MAINTENANCE CHECKED THE CMC FOR MESSAGES AND FOUND A RT TRANSMISSION FAIL CMC.  THE RIGHT FLAP TRANSMISSION BRAKE AND THE FLAP SYSTEM OPERATED NORMALLY.
