THE PILOT STATED THAT AT 65 MPH ON TAKEOFF, A SUDDEN CROSSWIND GUST HIT THE AIRPLANE, LIFTING IT INTO THE AIR, AND THAT HE COULD NOT SUBSEQUENTLY MAINTAIN ALTITUDE AT FULL POWER. HOWEVER, A WITNESS AT THE AIRPORT STATED THAT HE NOTICED NO UNUSUAL WIND GUSTS DURING THE EVENT. WITNESSES STATED THAT THE AIRPLANE WENT RIGHT WING DOWN, LEFT WING DOWN, RIGHT WING DOWN AGAIN, THEN LEFT WING DOWN, CONTACTING THE GROUND; AND THAT THE AIRPLANE THEN CRASHED INTO A FIELD. A NEARBY WEATHER OBSERVATION FACILITY REPORTED THE WIND AS SOUTHERLY AT 9 KNOTS. DENSITY ALTITUDE WAS 6,944 FEET.
