Narrative:

Maximum weight takeoff, hot, bleeds off, flaps 1 degree, engine parameters normal. QRH shows maximum takeoff egt to be 930 degrees C. Approximately 1000 ft AGL, #2 egt went to 957 degrees C and red light in gauge came on for 2-3 seconds. We were just selecting climb thrust so egt immediately subsided. ZZZ maintenance contacted and we were told to continue to bwi since the overtemp was less than 5 seconds. I then contacted maintenance control to get their input. They were able to categorize it for me as a class B excursion -- the second one in a couple of days. They also said to continue. We did, and flight was uneventful. Several problems come to mind: what are the real egt limits and duration so the crews will have knowledge of when to continue and when to turn back? At 930 degrees C, all we know is an overtemp occurred and we make a logbook entry and call maintenance. We must take them at their word. I'm uncomfortable with that.

Original NASA ASRS Text

Title: A B737 ON TKOF AND INITIAL CLB EXCEEDED MAX TKOF EXHAUST GAS TEMP ON #2 ENG.

Narrative: MAX WT TKOF, HOT, BLEEDS OFF, FLAPS 1 DEG, ENG PARAMETERS NORMAL. QRH SHOWS MAX TKOF EGT TO BE 930 DEGS C. APPROX 1000 FT AGL, #2 EGT WENT TO 957 DEGS C AND RED LIGHT IN GAUGE CAME ON FOR 2-3 SECONDS. WE WERE JUST SELECTING CLB THRUST SO EGT IMMEDIATELY SUBSIDED. ZZZ MAINT CONTACTED AND WE WERE TOLD TO CONTINUE TO BWI SINCE THE OVERTEMP WAS LESS THAN 5 SECONDS. I THEN CONTACTED MAINT CTL TO GET THEIR INPUT. THEY WERE ABLE TO CATEGORIZE IT FOR ME AS A CLASS B EXCURSION -- THE SECOND ONE IN A COUPLE OF DAYS. THEY ALSO SAID TO CONTINUE. WE DID, AND FLT WAS UNEVENTFUL. SEVERAL PROBS COME TO MIND: WHAT ARE THE REAL EGT LIMITS AND DURATION SO THE CREWS WILL HAVE KNOWLEDGE OF WHEN TO CONTINUE AND WHEN TO TURN BACK? AT 930 DEGS C, ALL WE KNOW IS AN OVERTEMP OCCURRED AND WE MAKE A LOGBOOK ENTRY AND CALL MAINT. WE MUST TAKE THEM AT THEIR WORD. I'M UNCOMFORTABLE WITH THAT.
