The pilot tried to correct back to the right, however the left wing contacted brush on the side of the narrow airstrip. The airplane was subsequently pulled around and the left wing contacted the surface. Both wings and the fuselage were substantially damaged. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that during the takeoff roll on a dirt airstrip that was rutted and rough, the airplane veered to the left of centerline.

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.
