NTSB narrative
The pilot reported that he had been landing and departing from the grass strip numerous times earlier in the day. For the accident flight, he was attempting to perform a midfield takeoff. During the departure roll, the airplane momentarily became airborne and then settled back into the wet grass and slowed. He opted to immediately abort the takeoff by retarding the throttle control and applying brakes. The airplane then slid off the end of the grass strip and collided with a ditch, incurring damage to the right wing and tail. The pilot reported no pre impact mechanical malfunctions or failures with the airframe or engine.
Probable cause
The pilot's decision to not use all available runway length and his delay in aborting the takeoff, which resulted in the airplane sliding off the end of the grass strip and colliding with a ditch.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2010-06-27.
