B727 aircraft on initial climb encountered windshear to which flight crew reacted correctly by adding maximum power. Because of the windshear aircraft climbed slowly until through it and then flight crew noticed #2 engine in redline, so reduced the thrust. That reduced climb rate and flight crew had to deviate heading to maintain terrain clearance. Controller intervened questioning their heading and altitude.

Narrative:
During takeoff at rno runway 16R, winds 130 degrees at 38 KTS, with a windshear alert on ATIS, a windshear warning occurred at approximately 50 ft AGL. All throttles were advanced to the firewall. Climb slow at first, with normal acceleration occurring after approximately 10 seconds. Egt redline exceeded on center engine. During power reduction after normal climb established, automatic pack system tripped resulting in loss of pressurization. Climb stopped at 10000 ft to re- establish pressurization. ATC questioned us on departure since we were not maintaining minimum climb gradient (this was due to power reduction to control overtemp and initial sluggish climb due to windshear). We were in VFR conditions and terrain clearance was not a problem. Aircraft also in moderate turbulence during this time. Departure SID modified to clear terrain. Again ATC questioned us on our course, advising us that we were close to restr airspace. By then, pressurization was working and all engines operating normally, we returned to course and normal climb profile. The egt on the center engine was above our book shutdown limits. We contacted our maintenance via radio. They had a higher limit. We elected to keep engine running and continue flight.

Title: B727 ACFT ON INITIAL CLB ENCOUNTERED WINDSHEAR TO WHICH FLC REACTED CORRECTLY BY ADDING MAX PWR. BECAUSE OF THE WINDSHEAR ACFT CLBED SLOWLY UNTIL THROUGH IT AND THEN FLC NOTICED #2 ENG IN REDLINE, SO REDUCED THE THRUST. THAT REDUCED CLB RATE AND FLC HAD TO DEVIATE HDG TO MAINTAIN TERRAIN CLRNC. CTLR INTERVENED QUESTIONING THEIR HDG AND ALT.
Narrative: DURING TKOF AT RNO RWY 16R, WINDS 130 DEGS AT 38 KTS, WITH A WINDSHEAR ALERT ON ATIS, A WINDSHEAR WARNING OCCURRED AT APPROX 50 FT AGL. ALL THROTTLES WERE ADVANCED TO THE FIREWALL. CLB SLOW AT FIRST, WITH NORMAL ACCELERATION OCCURRING AFTER APPROX 10 SECONDS. EGT REDLINE EXCEEDED ON CTR ENG. DURING PWR REDUCTION AFTER NORMAL CLB ESTABLISHED, AUTO PACK SYS TRIPPED RESULTING IN LOSS OF PRESSURIZATION. CLB STOPPED AT 10000 FT TO RE- ESTABLISH PRESSURIZATION. ATC QUESTIONED US ON DEP SINCE WE WERE NOT MAINTAINING MINIMUM CLB GRADIENT (THIS WAS DUE TO PWR REDUCTION TO CTL OVERTEMP AND INITIAL SLUGGISH CLB DUE TO WINDSHEAR). WE WERE IN VFR CONDITIONS AND TERRAIN CLRNC WAS NOT A PROB. ACFT ALSO IN MODERATE TURB DURING THIS TIME. DEP SID MODIFIED TO CLR TERRAIN. AGAIN ATC QUESTIONED US ON OUR COURSE, ADVISING US THAT WE WERE CLOSE TO RESTR AIRSPACE. BY THEN, PRESSURIZATION WAS WORKING AND ALL ENGS OPERATING NORMALLY, WE RETURNED TO COURSE AND NORMAL CLB PROFILE. THE EGT ON THE CTR ENG WAS ABOVE OUR BOOK SHUTDOWN LIMITS. WE CONTACTED OUR MAINT VIA RADIO. THEY HAD A HIGHER LIMIT. WE ELECTED TO KEEP ENG RUNNING AND CONTINUE FLT.
