Narrative:
With light snow, we deiced with type 1 50/50 glycol and proceeded to runway 4. The snow intensified during the taxi and after 4-6 mins, there was visible ice on the wing. We returned to the gate, at which time the snow was light again. So we deiced again with type 1 50/50 glycol (the only type available at the time) and decided to depart from runway 22 which was much closer to the ramp. As we were cleared for takeoff, well within the holdover time, we did a visual inspection of the wings and they appeared clear of ice. We also performed a stall test as we rolled onto the runway. I added full power and called 'set power.' the captain called 'power set, 80 KTS.' I said 'crosschecked.' at V1 the captain said 'V1, rotate' at which point I rotated and as I rotated, the stall warning horn immediately sounded. The captain called 'abort, abort' and brought the power back. We were approximately 10 ft off the ground at that point. When I realized the power was back, I landed the plane and immediately brought the power levers into reverse, at which point we stopped on the runway with approximately 500-1000 ft remaining. It was discovered later that there was something stuck inside of the stall vane which caused it to not be able to move down and function properly. The only thing I can come up with that could prevent a recurrence is more emphasis on the consequences of a post V1 abort throughout training.

Title: B190 CREW ABORTED TKOF AFTER AIRBORNE ON RWY 22 AT LEX.
Narrative: WITH LIGHT SNOW, WE DEICED WITH TYPE 1 50/50 GLYCOL AND PROCEEDED TO RWY 4. THE SNOW INTENSIFIED DURING THE TAXI AND AFTER 4-6 MINS, THERE WAS VISIBLE ICE ON THE WING. WE RETURNED TO THE GATE, AT WHICH TIME THE SNOW WAS LIGHT AGAIN. SO WE DEICED AGAIN WITH TYPE 1 50/50 GLYCOL (THE ONLY TYPE AVAILABLE AT THE TIME) AND DECIDED TO DEPART FROM RWY 22 WHICH WAS MUCH CLOSER TO THE RAMP. AS WE WERE CLRED FOR TKOF, WELL WITHIN THE HOLDOVER TIME, WE DID A VISUAL INSPECTION OF THE WINGS AND THEY APPEARED CLR OF ICE. WE ALSO PERFORMED A STALL TEST AS WE ROLLED ONTO THE RWY. I ADDED FULL PWR AND CALLED 'SET PWR.' THE CAPT CALLED 'PWR SET, 80 KTS.' I SAID 'XCHKED.' AT V1 THE CAPT SAID 'V1, ROTATE' AT WHICH POINT I ROTATED AND AS I ROTATED, THE STALL WARNING HORN IMMEDIATELY SOUNDED. THE CAPT CALLED 'ABORT, ABORT' AND BROUGHT THE PWR BACK. WE WERE APPROX 10 FT OFF THE GND AT THAT POINT. WHEN I REALIZED THE PWR WAS BACK, I LANDED THE PLANE AND IMMEDIATELY BROUGHT THE PWR LEVERS INTO REVERSE, AT WHICH POINT WE STOPPED ON THE RWY WITH APPROX 500-1000 FT REMAINING. IT WAS DISCOVERED LATER THAT THERE WAS SOMETHING STUCK INSIDE OF THE STALL VANE WHICH CAUSED IT TO NOT BE ABLE TO MOVE DOWN AND FUNCTION PROPERLY. THE ONLY THING I CAN COME UP WITH THAT COULD PREVENT A RECURRENCE IS MORE EMPHASIS ON THE CONSEQUENCES OF A POST V1 ABORT THROUGHOUT TRAINING.
