Sequence of events

Analysis

The pilot reported that he was taking off from an 80-foot-wide, rough grass airstrip to conduct an aerial application flight. During the takeoff roll, the airplane began to bounce and drift to the right. The airplane’s right wing contacted the adjacent corn crop, and the airplane veered further right into the corn field, where it nosed over. The airplane sustained substantial damage to both wings and the fuselage. The pilot stated that he did not experience any preimpact mechanical malfunctions or failures that would have precluded normal operation.
