NTSB narrative
The pilot of a powered glider reported that during the landing roll on a narrow grass airstrip, the glider veered to the left of centerline. He attempted to correct for the veer with right rudder input, but was unsuccessful. The left main landing gear traveled over a slope in the runway [crown for drainage purposes] and the left wing impacted corn stalks. The glider spun to the left and slid down the drainage area into the corn field.
The glider sustained substantial damage to the fuselage.
The pilot reported no preaccident mechanical malfunctions or failures with the powered glider that would have precluded normal operation.
Probable cause
The pilot's failure to maintain directional control of the powered glider during the landing roll.

Source notes (4)
- 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: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
