GULFSTREAM GIV FLT CREW HAS AN OVERTEMP DURING ENG START.

Narrative

STARTING ENG WE GOT A HOT START. SHUT DOWN ENG AND COOLED. CHKED PLT'S QRH MANUAL AS WELL AS AIRPLANE FLT MANUAL. AFTER REVIEWING DOCUMENTS; RESTARTED ENG AND PROCEEDED TO COMPLETE FLT. NOTICED WHEN WE GOT TO HOME BASE THAT WE EXCEEDED TEMP LIMITS ON THE OTHER ENG AS WELL. ACFT HAD BEEN SITTING ON RAMP FOR 4 DAYS. DURING THIS TIME APPROX 8 INCHES OF SNOW ACCUMULATED ON ACFT. ALTHOUGH BOTH I AND THE CAPT WENT OUT TO THE ACFT THE DAY BEFORE THE DEP AND CLEANED OFF THE SNOW FROM WINGS AND AREAS WE COULD REACH THERE WERE AREAS WE COULD NOT REACH. WE DEICED ACFT BEFORE DEP WITH PAX ON BOARD. AFTER LENGTHY DEICE BOTH CAPT AND I EXITED ACFT AND DID A WALKAROUND CHKING ALL FLT SURFACES. I HAVE TO ASSUME A LARGE POOL OF DEICE FLUID POOLED IN ENG COWLING AND CONTRIBUTED TO HOT START. I HAVE HAD NUMEROUS TRIPS IN AND OUT OF HIGH ALT ARPTS BOTH IN HOT AND COLD CONDITIONS AND AM WELL VERSED IN COLD/HIGH OPS PROCS. WE SAW THE TEMP CLBING ON ENG START AND SHUT IT DOWN AS FAST AS WE COULD. AFTER DOWNLOADING FAULT WARNING COMPUTERS WE FIND THAT BOTH ENGS EXCEEDED START TEMP LIMIT ON START. WE DID NOT GET AN INDICATION FROM THE OTHER ENG OF AN OVERTEMP. WE HAVE REMOVED THE FDR AND HAVE SENT IT TO BE REVIEWED BY ACFT AND ENG MANUFACTURER. THE DOCUMENTS THAT WE REFERRED TO FOR HOT START (HOT START CHKLIST) DID NOT LIMIT US FROM STARTING THE ENG THAT SHOWED THE HOT START. AS LONG AS SECOND START STAYED BELOW 700 DEGS C WHICH IT DID. HOWEVER; WE NOW FIND OUT THAT THE ENG MANUFACTURER SAYS WE SHOULD NOT HAVE ATTEMPTED A RESTART.
