N5011X departed 5AZ9, a private airstrip, to take photos of the same airfield. No weather services were provided at this airfield. The wind was observed by the pilot via windsock to be variable from the west to northwest and estimated to be 5-7 knots. The flight started with a normal takeoff on runway 35(a down sloping runway) at approximately 1:40P.m. local time. Once the photos were taken, a normal traffic pattern entry was flown for runway 17 (an up sloping runway). Winds were observed to be same as they were at takeoff. The approach was flown with full flaps and a normal wheel landing was made. After touchdown, an estimated 100 yards of normal rollout on all three landing gear was accomplished. Then, at approximately mid-field a sudden gust of wind from the west (or a possible dust devil) was encountered by the pilot. During this encouter the the pilot tried to input corrective action using rudder and brake pressure, however, the aircraft departed the right (west) side of the runway. As the aircraft departed the runway the left wing tip impacted the ground. The aircraft then impacted a berm area caused the right wing to impact the ground and the nose to pitch over and inpact in the ground where the aircraft came to a stop. The pilot then shut down the electrical equipment and all three passengers exited the aircraft from them left door. No one was injured. The damage to the aircraft was substantial.
