Accident Description
According to the pilot, the flight lasted approximately 10 minutes before he initiated a normal traffic pattern approach. The landing touchdown was uneventful, and the initial rollout proceeded without incident. Shortly after the tail wheel was lowered, the airplane encountered an abrupt gust of wind from the right. The pilot characterized this gust as a dust devil swirl of air. At that moment, rudder effectiveness was significantly reduced. Despite the pilot's attempts to keep the airplane aligned with the runway, the left wing tip contacted the ground. This caused the airplane to depart the runway surface and strike a berm. Additionally, the right wing tip impacted the terrain.
Damage
The impact resulted in a bent outboard section of the left wing and a deformed right wing strut.
Pilot's Account
The pilot stated that he had no advance warning of the dust devil swirl and did not provide a speed estimate for the gust in his report. The airport used for departure and landing lacks any official weather reporting services. However, the pilot noted that the windsock indicated wind speeds between 5 and 7 knots prior to the incident. No mechanical malfunctions or failures were reported with the airplane.
