## Discrepancy

ON DESCENT INTO CMH, RECEIVED NUMEROUS EICAS CAUTIONS AND ADVISORY MESSAGES, LOST SEVERAL INDICATIONS/COMPONENTS.  BEGAN TROUBLESHOOTING SITUATION AND LEARNED THAT WITH MAU 2B AND MAU 3A FAILED, WOULD HAVE NO MULTI-FUNCTION SPOILERS (FLIGHT CONTROL), DECLARED THE EMERGENCY 10 MINUTES FROM CMH.  FINALLY SAW TRU 2 HAD FAILED AND RAN THAT QRH PROCEDURE.  AFTER RESETTING THE TRU, ALL SYSTEMS/INDICATIONS WERE RESTORED AND REPORTED TO ATC, NO LONGER HAD AN EMERGENCY AND THAT EVERYTHING WAS BACK TO NORMAL.  PER MAINTENANCE CONTROL REQUEST, THE TRU 2 WAS REPLACED.
