A BAE4100 ON #1 ENG START WITH LOW MINIMUM BATTERY VOLTAGE RESULTED IN A HUNG START AND EXHAUST GAS TEMP LIMIT WAS EXCEEDED.

Narrative

ON MY FIRST FLT OUT OF IOE AS CAPT ON THE JETSTREAM 4100; I WAS ASSIGNED A FLT FROM XXX TO ZZZ INTL. ONCE WE ARRIVED IN ZZZ; WE WERE INFORMED THAT XXX WAS CLOSED BRIEFLY DUE TO WX. A COMPANY JETSTREAM 3200 WAS ON THE RAMP AS WELL; AND IT HAD THE ONLY OPERATIVE GPU CONNECTED TO IT. WHEN THE GND STOP TO XXX WAS LIFTED; WE HAD TO LEAVE FIRST BECAUSE WE WERE BLOCKING THE J32'S EXIT. I INFORMED THE RAMPER THAT I HAD MINIMUM BATTERY VOLTAGE FOR THE BATTERY START. HE DIDN'T WANT TO UNHOOK THE GPU FROM OUR COMPANY J32; SO I INITIATED A BATTERY START WITH THE MINIMUM BATTERY VOLTAGE ALLOWABLE FOR START. DURING THE START SEQUENCE (L ENG); WE EXPERIENCED A HUNG START AND I ABORTED THE START. I REQUESTED A GPU TO START THE R ENG WHILE THE L ENG COOLED DOWN. ONCE IT WAS COOLED BELOW 200 DEGS C; MAX RESIDUAL EGT FOR START; WE STARTED THE L ENG WITH NO ABNORMALITIES. ON TAXI OUT; WE EXPERIENCED A L INTEGRATED ELECTRONIC COMPUTER LIGHT. THE INTEGRATED ELECTRONIC COMPUTER CTLS THE DISPLAYED LIMIT FOR THE EGT AS WELL AS THE TEMP READOUT. I CONFIRMED THAT THESE FUNCTIONS WERE STILL OPERATING NORMALLY AND ASSUMED WE HAD AN ERRONEOUS INDICATION. WE RAN THE CHKLIST ITEMS AND RESET THE L INTEGRATED ELECTRONIC COMPUTER AND THE LIGHT WENT OUT. AFTER TKOF; DURING OUR CLB THROUGH 3000 FT MSL; THE L INTEGRATED ELECTRONIC COMPUTER LIGHT ILLUMINATED AGAIN AND WE RAN THE CHKLIST ITEMS. THE LIGHT WENT OUT FOR A FEW MINS; JUST AS ON THE TXWY; BUT EVENTUALLY CAME BACK ON. I WROTE THE LIGHT UP AND RPTED IT TO MAINT IN XXX. THEY HOOKED A HANDHELD COMPUTER INTO THE MAINT PANEL AND RESET THE LIGHT. DURING THE RESET; I INFORMED THE MECH THAT WE HAD EXPERIENCED A HUNG START ON THE L ENG TO AID HIM IN TROUBLESHOOTING. ENG DATA WAS DOWNLOADED AND TAKEN BACK TO OUR MAINT HANGAR. LATER THAT EVENING; OUR MAINT SUPVR CALLED ME AT HOME AND INFORMED MME THAT THE 770 DEGS C EGT LIMIT WAS EXCEEDED ON THE L ENG DURING START. I INFORMED HIM THAT THE START WAS ABORTED WELL BEFORE 770 DEGS C AND I NEVER SAW THE TEMP RISE ABOVE THE 770 DEGS C LIMIT. HE ASKED ME IF I WAS COMFORTABLE WITH HIM PUTTING A STATEMENT IN THE ACFT MAINT LOG TO CONFIRM THE TEMP EXCEEDANCE WAS FOR ONLY A SPLIT SECOND. I TOLD HIM I WAS QUITE COMFORTABLE WITH THAT STATEMENT AND I REPEATED THE FACT THAT IT MUST HAVE BEEN SUCH A QUICK EXCEEDANCE THAT I NEVER OBSERVED IT. THE MECH INFORMED ME THAT THE EXCEEDANCE WAS WITHIN MAINT LIMITS AND THE ACFT WAS FINE TO CONTINUE SVC WITHOUT ANY INSPECTION.
