Narrative:

We were in line #3 for takeoff for a flight from boi, identification, to sea, wa. We were behind a B737, the ambient conditions were 92 degrees F, winds northwest at 6 KTS. Our position was about 50 ft behind the B737. The #1 tgt warning sounded. We noted the tgt at 520 degrees C (the limit is 520 degrees). We shut down the engine and did the 'tgt running' checklist. About the time we finished the checklist #2 engine tgt warning sounded with a steady temperature of 515-520 degrees. We shut down #2 engine and allowed them to cool (and the B737 ahead to move away from us). We attempted a start on #1 engine but it became a hot start. (I believe I did not let the engine cool sufficiently.) we then tried #2 engine and got it started. We then did a xbleed start and got the #1 engine started. All indications were normal, so we continued on to sea. I believe this condition was caused both by the warm exhaust from the B737 ahead and the quartering tailwind blowing up the tail pipes. Closer monitoring of tgt's and engine RPM would have prevented this occurrence.

Title: FLC EXPERIENCES OVERTEMP ON BOTH ENGS WHILE WAITING BEHIND B737 FOR TKOF.

Narrative: WE WERE IN LINE #3 FOR TKOF FOR A FLT FROM BOI, ID, TO SEA, WA. WE WERE BEHIND A B737, THE AMBIENT CONDITIONS WERE 92 DEGS F, WINDS NW AT 6 KTS. OUR POS WAS ABOUT 50 FT BEHIND THE B737. THE #1 TGT WARNING SOUNDED. WE NOTED THE TGT AT 520 DEGS C (THE LIMIT IS 520 DEGS). WE SHUT DOWN THE ENG AND DID THE 'TGT RUNNING' CHKLIST. ABOUT THE TIME WE FINISHED THE CHKLIST #2 ENG TGT WARNING SOUNDED WITH A STEADY TEMP OF 515-520 DEGS. WE SHUT DOWN #2 ENG AND ALLOWED THEM TO COOL (AND THE B737 AHEAD TO MOVE AWAY FROM US). WE ATTEMPTED A START ON #1 ENG BUT IT BECAME A HOT START. (I BELIEVE I DID NOT LET THE ENG COOL SUFFICIENTLY.) WE THEN TRIED #2 ENG AND GOT IT STARTED. WE THEN DID A XBLEED START AND GOT THE #1 ENG STARTED. ALL INDICATIONS WERE NORMAL, SO WE CONTINUED ON TO SEA. I BELIEVE THIS CONDITION WAS CAUSED BOTH BY THE WARM EXHAUST FROM THE B737 AHEAD AND THE QUARTERING TAILWIND BLOWING UP THE TAIL PIPES. CLOSER MONITORING OF TGT'S AND ENG RPM WOULD HAVE PREVENTED THIS OCCURRENCE.
