Narrative:
We were cleared for runway 33L bwi ILS. At this point our airspeed was +/-15 KTS with moderate turbulence, but still on localizer and GS. Fuel was still an issue, which caused us to continue the approach. I asked for flaps 15 degrees, which was selected, then attempted to contact tower. While he was changing the frequency, we were hit with the windshear. First we climbed at 1500-2000 FPM at flight idle at around 210 KTS, then we slowed to about 160 KTS when we lost about 70 KTS of airspeed and got at stick shaker at around 90 KTS. I asked for go around power. As I rushed the power levels forward, with both hands on the yoke, I lowered the nose. We were 2 dots high on the GS and the airspeed was now coming back quickly, so I reduced the power and slowed back to 150 KTS. The rest of the approach was flown in heavy rain and moderate turbulence. We broke out at about 1700 ft with the airport in sight. Landing was uneventful, with no injuries to the passenger. 6 days later, I was informed by my chief pilot that an overtorque situation had occurred. No time to the best of my knowledge had the engines been overtorqued.

Title: CREW RECOVERED FROM SEVERE WINDSHEAR WHICH REQUIRED FULL THROTTLE TRAVEL WHICH OVERTORQUED BOTH ENGS.
Narrative: WE WERE CLRED FOR RWY 33L BWI ILS. AT THIS POINT OUR AIRSPD WAS +/-15 KTS WITH MODERATE TURB, BUT STILL ON LOC AND GS. FUEL WAS STILL AN ISSUE, WHICH CAUSED US TO CONTINUE THE APCH. I ASKED FOR FLAPS 15 DEGS, WHICH WAS SELECTED, THEN ATTEMPTED TO CONTACT TWR. WHILE HE WAS CHANGING THE FREQ, WE WERE HIT WITH THE WINDSHEAR. FIRST WE CLBED AT 1500-2000 FPM AT FLT IDLE AT AROUND 210 KTS, THEN WE SLOWED TO ABOUT 160 KTS WHEN WE LOST ABOUT 70 KTS OF AIRSPD AND GOT AT STICK SHAKER AT AROUND 90 KTS. I ASKED FOR GAR PWR. AS I RUSHED THE PWR LEVELS FORWARD, WITH BOTH HANDS ON THE YOKE, I LOWERED THE NOSE. WE WERE 2 DOTS HIGH ON THE GS AND THE AIRSPD WAS NOW COMING BACK QUICKLY, SO I REDUCED THE PWR AND SLOWED BACK TO 150 KTS. THE REST OF THE APCH WAS FLOWN IN HVY RAIN AND MODERATE TURB. WE BROKE OUT AT ABOUT 1700 FT WITH THE ARPT IN SIGHT. LNDG WAS UNEVENTFUL, WITH NO INJURIES TO THE PAX. 6 DAYS LATER, I WAS INFORMED BY MY CHIEF PLT THAT AN OVERTORQUE SIT HAD OCCURRED. NO TIME TO THE BEST OF MY KNOWLEDGE HAD THE ENGS BEEN OVERTORQUED.
