Approach and Landing
The pilot circled the field twice before preparing for a landing to the south with full flaps. During the final approach, the pilot flew as close as possible to the trees and then performed a slip maneuver to lose altitude. The airplane touched down halfway along the 2,500-foot-long turf runway.
Runway Excursion
After touchdown, the pilot retracted the flaps and applied maximum braking. According to the pilot, directional control was lost during the landing rollout. The airplane ran off the left side of the runway and spun 180 degrees.
Impact and Damage
During the excursion, the airplane struck a knoll. The impact substantially damaged both wings. The pilot reported no mechanical deficiencies with the airplane.
