Analysis
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.
