## Analysis

THE ACCIDENT SEQUENCE WAS OBSERVED BY TWO PILOTS WHO WERE AWAITING TAKEOFF AT THE APPROACH END OF THE RWY IN USE. ONE OF THE PILOTS REPORTED THAT THE PLT OF THE ACDT ACFT ADVISED HIM THAT THE ACDT ACFT HAD ENCOUNTERED ICE DURING THE FLIGHT. THE ACDT ACFT WAS OBSERVED ON A 'TIGHT' DOWNWIND OPPOSITE THE TOUCHDOWN POINT AT ABOUT 600 FT AGL. AT THAT POINT THE WINGS OF THE ACDT ACFT DIPPED FROM SIDE TO SIDE 4 OR 5 TIMES. NEXT, THE ACFT MADE A LEFT, DESCENDING TURN TOWARD THE RWY. DURING THE TURN, THE LT WING DROPPED SUDDENLY AND THE ACFT DESCENDED TO THE GROUND FROM ABOUT 200 - 300 FT AGL. ONE ON THE FIRST WITNESSES TO ARRIVE AT THE ACDT SCENE, ABOUT 45 MIN AFTER THE ACDT OCCURRED, REPORTED SEEING ICE ON THE TOP OF ACDT ACFT WING. A WITNESS REPORTED THE TEMP AT THE TIME OF THE ACDT WAS 38 DEG F.
