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

As the airplane accelerated through about 50 knots during the takeoff roll, the airplane's right wing began to lift. When the pilot attempted to lower the right wing, the airplane veered to the left and exited the left side of the runway. The airplane entered a ditch and came to rest upright and partially submerged in water. Postaccident examination of the airplane showed substantial damage to both wings. The pilot reported no preaccident mechanical malfunctions or failures that would have precluded normal operation.
