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.
