THERE WAS FIRE DAMAGE TO THE LOWER AFT WING SKIN, FLAP AND FLAP TRACK FAIRING BEHIND THE RIGHT ENGINE.  THERE WAS NO APPARENT DAMAGE TO THE ENGINE, TAIL CONE, OR PYLON.  THE ENGINE INDICATING AND CREW ALERTING SYSTEM (EICAS) DATA INDICATED THAT NO N1 SPEED WAS RECORDED, FUEL FLOW WAS ABNORMALLY HIGH AND BURNER PRESSURE WAS RECORDED THREE TIMES HIGHER THAN NORMAL DURING THE ABORTED START.
