Narrative:

Approach to dfw with storms/showers in the area. A WX line northwest to southeast just south of the field (5-7 mi) painted on radar. Although line showed red, it appeared to be thin with no adverse PIREPS. Decision made to continue. On descent to estimated glidepath, had difficulty descending and slowing. With approach not stabilizing and recognition of excessive descent rate/angle to estimated slot, a go around was made. After gear retraction, a loss of elevator authority/authorized occurred with altitude stagnating at approximately 2500 ft and airspeed of 160 KTS, followed by a return and subsequent loss of elevator authority/authorized again at 3000 ft, this episode lasting longer than the first. Throughout recovery, GPWS pull-up and terrain aural warning sounded with red box items accomplished. I do not recall the windshear avoidance system activating throughout the recovery. During recovery, turbulence was moderate with heavy rain and lightning. Following third loss and regain of elevator authority/authorized, altitude climbed rapidly to 6000 ft. Throttle reduction occurred at 7000 ft with leveloff at 10500 ft and return to stable at 10000 ft. Subsequent vectors, discussion of alternate and repeated checks of the WX line's movement led to another approach with normal landing.

Title: FLC OF A SUPER MD80 MOMENTARILY LOST CTL OF THE ACFT ON 3 DIFFERENT OCCASIONS, AND HEARD GPWS TERRAIN WARNINGS, DURING AN ILS APCH, AND SUBSEQUENT GAR DUE TO ENTERING EXTREME WINDSHEAR. THE WINDSHEAR WARNING SYS WAS NOT HEARD THROUGHOUT THE WINDSHEAR WX ENCOUNTER. CTL OF THE ACFT WAS FINALLY RE-ESTABLISHED AFTER EXITING THE WINDSHEAR DURING GAR CLB.

Narrative: APCH TO DFW WITH STORMS/SHOWERS IN THE AREA. A WX LINE NW TO SE JUST S OF THE FIELD (5-7 MI) PAINTED ON RADAR. ALTHOUGH LINE SHOWED RED, IT APPEARED TO BE THIN WITH NO ADVERSE PIREPS. DECISION MADE TO CONTINUE. ON DSCNT TO ESTIMATED GLIDEPATH, HAD DIFFICULTY DSNDING AND SLOWING. WITH APCH NOT STABILIZING AND RECOGNITION OF EXCESSIVE DSCNT RATE/ANGLE TO ESTIMATED SLOT, A GAR WAS MADE. AFTER GEAR RETRACTION, A LOSS OF ELEVATOR AUTH OCCURRED WITH ALT STAGNATING AT APPROX 2500 FT AND AIRSPD OF 160 KTS, FOLLOWED BY A RETURN AND SUBSEQUENT LOSS OF ELEVATOR AUTH AGAIN AT 3000 FT, THIS EPISODE LASTING LONGER THAN THE FIRST. THROUGHOUT RECOVERY, GPWS PULL-UP AND TERRAIN AURAL WARNING SOUNDED WITH RED BOX ITEMS ACCOMPLISHED. I DO NOT RECALL THE WINDSHEAR AVOIDANCE SYS ACTIVATING THROUGHOUT THE RECOVERY. DURING RECOVERY, TURB WAS MODERATE WITH HVY RAIN AND LIGHTNING. FOLLOWING THIRD LOSS AND REGAIN OF ELEVATOR AUTH, ALT CLBED RAPIDLY TO 6000 FT. THROTTLE REDUCTION OCCURRED AT 7000 FT WITH LEVELOFF AT 10500 FT AND RETURN TO STABLE AT 10000 FT. SUBSEQUENT VECTORS, DISCUSSION OF ALTERNATE AND REPEATED CHKS OF THE WX LINE'S MOVEMENT LED TO ANOTHER APCH WITH NORMAL LNDG.
