The pilot completed the 8th seeding pass over a field and was turning to make the 9th pass when the agricultural airplane shuddered and made three uncommanded banks prior to impacting the terrain. The pilot initially stated that he flew through his own wake turbulence and stalled the airplane while in a 60-degree bank to the right. However, the pilot later stated that he thought the propeller may have malfunctioned resulting in the loss of airplane control. Post-accident examination of the airplane flight controls and the propeller revealed no anomalies that would have prevented normal operation of the aircraft prior to the accident.
Probable Cause: The pilot's inadvertent stall. A factor was the pilot's encounter with the airplane's wake turbulence.
