What happened
The pilot was performing a low-level left turnaround to begin a swath run when the aircraft began to lose airspeed. During the highest part of the turn, the aircraft was in a steep left bank. As the aircraft approached the ground, the pilot was unable to raise the left wing sufficiently.
As a result, the left wing and the main landing gear made contact with the ground. The aircraft then slid sideways across the terrain before coming to a complete stop. The pilot reported that there were no mechanical issues with the aircraft prior to the event. He noted that he had been turning into a wind of 6 to 8 knots but believed the wind may have ceased during the execution of the turn, contributing to the loss of airspeed.
No injuries were reported in the accident.
