Accident Details
A pilot reported fueling the airplane to maximum gross weight to assess its flight characteristics during maneuvers. After practicing stalls and slow flight, the pilot approached the airport for landing. The pilot stated that a slightly higher approach speed was used in consideration of the increased weight. During the approach, the windsock indicated no crosswind, hanging down.
The landing was described as normal, true, and straight, but the roll out was slightly longer than usual. As excess speed dissipated, the left wing began to rise. The pilot applied left aileron and left rudder to correct the wing rise. Upon looking up, the pilot realized the aircraft was veering to the right. Braking was applied, but the aircraft departed the asphalt runway onto very soft sand and dirt at approximately 25 knots, where it nosed over.
Damage
The accident resulted in damage to the aircraft: the vertical stabilizer and rudder were bent and wrinkled, the left wing struts were bent, and the right upper wing root was buckled.
Weather
The nearest weather reporting facility, located 17 nautical miles east of the accident site, recorded calm winds at the time of the accident.
