The NTSB's narrative final · quoted from the NTSB record

The pilot reported that the airplane encountered a wind gust during the landing roll, which lifted the left wing and caused the airplane to swerve to the right. The pilot responded with the application of full engine power to initiate an aborted landing, but the airplane encountered another wind gust that further lifted the left wing and caused the right wing to impact the ground. The airplane subsequently came to rest in a field next to the runway. The airplane's engine firewall, wings, and fuselage were substantially damaged. The pilot reported that there were no preimpact mechanical malfunctions or failures that would have precluded the normal operation of the airplane.
