THE SURFACE WEATHER OBSERVATION CHART AT THE TIME OF THE ACCIDENT INDICATES THAT THE SURFACE WINDS WERE FROM 260 DEGREES AT 5 KNOTS.  THE PILOT REPORTED THAT HE EXECUTED AN UNEVENTFUL WHEEL LANDING AND WHEN THE AIRPLANE DECELERATED HE BEGAN TO TURN OFF THE RUNWAY ONTO THE TAXIWAY WHEN A GUST OF WIND RAISED THE LEFT WING AND THEN THE AIRPLANE NOSED OVER.
