The pilot reported that, while taxiing to the runway for takeoff, the yoke was, "left and push in," a wind gust from the right lifted the right wing. The pilot was unable to maintain control and the wind continued to push the airplane to the left off the runway. The airplane subsequently nosed over.

The airplane sustained substantial damaged to the fuselage and empennage.

The pilot reported that there were no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The automated surface observing system located on the airport reported that, about the time of the accident, the wind was from 030° at 20 knots, gusting to 29 knots. The pilot was turning the airplane right onto runway 34.

The airplane manufacturer reported that the maximum demonstrated crosswind component was 15 knots. The calculated crosswind component while taxiing into takeoff position was approximately 19 knots.

The Federal Aviation Administration's Airplane Flying Handbook, FAA-H-8083-3B, provides information and guidance in a section titled "Taxiing" which stated in part:

When taxiing with a quartering headwind, the wing on the upwind side (the side that the wind is coming from) tends to be lifted by the wind unless the aileron control is held in that direction (upwind aileron UP). Moving the aileron into the UP position reduces the effect of the wind striking that wing, thus reducing the lifting action. This control movement also causes the downwind aileron to be placed in the DOWN position, thus a small amount of lift and drag on the downwind wing, further reducing the tendency of the upwind wing to rise.
