Narrative:
The pilot was taxiing into position for takeoff when a wind gust, reported by the tower, of 52 knots lifted the right wing of the airplane. The right wing continued to rotate the aircraft and move it to the left on the ramp. The pilot attempted to maintain control but was unsuccessful and the aircraft rolled inverted. The pilot was able to egress unassisted and was not injured. Weather forecast at the 40 minutes prior to the accident indicated forecast winds 250 degrees at 15 knots. At 7 minutes after the accident the updated weather observation showed winds from 260 degrees at 38 knots with gusts to 52 knots.
Probable Cause: The pilot and airplane's inability to compensate for the unforecasted gusting wind conditions.
