Narrative:
Departed tus runway 11. On cleanup at 1000 ft AGL, while at 2 degrees, just prior to final flap retraction, got 'windshear' audio with corresponding flashing red warning light. (Note: winds were gusting to 16 KTS on surface, from rotation through entire climb out it was smooth.) airspeed was steady with no fluctuations and no performance degradation observed. However, due to heavy weight, high outside air temperature, and close ground proximity, complied with company procedure and 'firewalled' engines. Windshear warning was cleared in 3-5 seconds. Throttles were retarded to climb power. All crew agreed we were at firewall for 3-5 seconds as a best guess estimate. All engines operated normally. (Maximum EPR observed was 2.3-2.4, egt went into red range momentarily.) decided to continue to destination (msp) due to normally operating engines and short duration of encounter. Called maintenance to find out what parameters were needed for a proper evaluation of engine condition. They said it was policy to pull the flight recorder. We wrote up a discrepancy in the aircraft logbook, including environmental parameters and short description of the event. Upon checking with maintenance the next day, found out #1 and #3 engines were within limits, but that #2 engine had exceeded egt limits for 3 seconds while N1 overspd for 5 seconds. In retrospect, it might have been prudent to get a full discussion with maintenance on the possible exceedance before continuing to destination.

Title: AN ACR FLC FLYING B727 FROM TUS EXPERIENCES WINDSHEAR AFTER TKOF AND DESCRIBES EXCEEDING MAX ENG PARAMETERS AFTER SETTING THE THRUST LEVERS TO THEIR PHYSICAL STOPS.
Narrative: DEPARTED TUS RWY 11. ON CLEANUP AT 1000 FT AGL, WHILE AT 2 DEGS, JUST PRIOR TO FINAL FLAP RETRACTION, GOT 'WINDSHEAR' AUDIO WITH CORRESPONDING FLASHING RED WARNING LIGHT. (NOTE: WINDS WERE GUSTING TO 16 KTS ON SURFACE, FROM ROTATION THROUGH ENTIRE CLBOUT IT WAS SMOOTH.) AIRSPD WAS STEADY WITH NO FLUCTUATIONS AND NO PERFORMANCE DEGRADATION OBSERVED. HOWEVER, DUE TO HVY WT, HIGH OUTSIDE AIR TEMP, AND CLOSE GND PROX, COMPLIED WITH COMPANY PROC AND 'FIREWALLED' ENGS. WINDSHEAR WARNING WAS CLRED IN 3-5 SECONDS. THROTTLES WERE RETARDED TO CLB PWR. ALL CREW AGREED WE WERE AT FIREWALL FOR 3-5 SECONDS AS A BEST GUESS ESTIMATE. ALL ENGS OPERATED NORMALLY. (MAX EPR OBSERVED WAS 2.3-2.4, EGT WENT INTO RED RANGE MOMENTARILY.) DECIDED TO CONTINUE TO DEST (MSP) DUE TO NORMALLY OPERATING ENGS AND SHORT DURATION OF ENCOUNTER. CALLED MAINT TO FIND OUT WHAT PARAMETERS WERE NEEDED FOR A PROPER EVALUATION OF ENG CONDITION. THEY SAID IT WAS POLICY TO PULL THE FLT RECORDER. WE WROTE UP A DISCREPANCY IN THE ACFT LOGBOOK, INCLUDING ENVIRONMENTAL PARAMETERS AND SHORT DESCRIPTION OF THE EVENT. UPON CHKING WITH MAINT THE NEXT DAY, FOUND OUT #1 AND #3 ENGS WERE WITHIN LIMITS, BUT THAT #2 ENG HAD EXCEEDED EGT LIMITS FOR 3 SECONDS WHILE N1 OVERSPD FOR 5 SECONDS. IN RETROSPECT, IT MIGHT HAVE BEEN PRUDENT TO GET A FULL DISCUSSION WITH MAINT ON THE POSSIBLE EXCEEDANCE BEFORE CONTINUING TO DEST.
