## Discrepancy

DURING A POST MX GROUND RUN AFTER A 10 SECOND DRY MOTOR OF BOTH ENGINES AND A COOL DOWN PERIOD, THE RT ENGINE WAS STARTED.  THE FIRE GUARD/GROUND RUN MONITOR NOTICED A FLAME IN THE VICINITY OF THE STARTER GENERATOR (THE LOWER COWLING WAS REMOVED).  AFTER HE SIGNALED FOR AN ENGINE SHUTDOWN HE WAS ABLE TO EXTINGUISH THE FLAME WITH A FIRE EXTINGUISHER.  SUBSEQUENT REMOVAL AND INSPECTION REVEALED THAT THERE WAS A PROBABLE SHORT IN THE STARTER/GENERATOR TERMINAL BLOCK.  THERE WAS SIGNIFICANT FIRE AND HEAT DAMAGE TO THE STARTER/GENERATOR WIRING WHICH WILL NEED TO BE REPLACED ALONG WITH A THOROUGH INSPECTION OF THE SURROUNDING AREA.  THE STARTER/GENERATOR WAS INSTALLED, O/H ON 7/18/2009 AND HAD A TSO OF 888.3 (TBO IS 1000 HOURS).
