An MD88 flight crew experienced windshear on final approach at atl and performed a missed approach. On that climb out windshear was still prevailing, which created an altitude overshoot with a subsequent diversion of the flight.

Narrative:

ILS to runway 9R at atl. WX was over north portion of airport, IMC, with mostly smooth ride. As we approached OM, the aircraft ahead of us reported +15 and -10 KTS on final. We adjusted final bug speed for wind and configured for landing. Approaching GS, airspeed increased to about 190 KTS. First officer (PF) elected to not reduce thrust due to reported airspeed fluctuations. At about 1400 ft AGL, airspeed began to decrease, accompanied by a decreasing performance windshear warning. First officer executed a standard recovery. Altitude loss was about 200 ft, but it took several seconds for climb to start, in spite of the thrust and nose high attitude. We told ATC we abandoned approach, and they assigned a south heading and 3500 ft MSL. The aircraft suddenly began a rapid climb. We were unable to stop the climb until about 4400 ft MSL -- even with the nose pitched down. ATC reassigned 4000 ft MSL. Flight diverted to bhm.

Original NASA ASRS Text

Title: AN MD88 FLC EXPERIENCED WINDSHEAR ON FINAL APCH AT ATL AND PERFORMED A MISSED APCH. ON THAT CLBOUT WINDSHEAR WAS STILL PREVAILING, WHICH CREATED AN ALT OVERSHOOT WITH A SUBSEQUENT DIVERSION OF THE FLT.

Narrative: ILS TO RWY 9R AT ATL. WX WAS OVER N PORTION OF ARPT, IMC, WITH MOSTLY SMOOTH RIDE. AS WE APCHED OM, THE ACFT AHEAD OF US RPTED +15 AND -10 KTS ON FINAL. WE ADJUSTED FINAL BUG SPD FOR WIND AND CONFIGURED FOR LNDG. APCHING GS, AIRSPD INCREASED TO ABOUT 190 KTS. FO (PF) ELECTED TO NOT REDUCE THRUST DUE TO RPTED AIRSPD FLUCTUATIONS. AT ABOUT 1400 FT AGL, AIRSPD BEGAN TO DECREASE, ACCOMPANIED BY A DECREASING PERFORMANCE WINDSHEAR WARNING. FO EXECUTED A STANDARD RECOVERY. ALT LOSS WAS ABOUT 200 FT, BUT IT TOOK SEVERAL SECONDS FOR CLB TO START, IN SPITE OF THE THRUST AND NOSE HIGH ATTITUDE. WE TOLD ATC WE ABANDONED APCH, AND THEY ASSIGNED A S HDG AND 3500 FT MSL. THE ACFT SUDDENLY BEGAN A RAPID CLB. WE WERE UNABLE TO STOP THE CLB UNTIL ABOUT 4400 FT MSL -- EVEN WITH THE NOSE PITCHED DOWN. ATC REASSIGNED 4000 FT MSL. FLT DIVERTED TO BHM.
