The airplane touched down onto the turf runway, bounced back into the air, and touched down a second time. The pilot applied brakes, realized he was running out of runway, and applied heavier braking. The airplane started to slide and, despite the pilot’s control inputs, overran the end of the runway and impacted a ditch. Subsequently, the left wing was substantially damaged. The pilot reported no mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. ## Factual narrative The pilot reported that on final approach he was concerned about some trees bracketing each side of the runway's approach end and he stayed high to clear them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
