Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, during the takeoff ground roll, he slowly started to pull the control stick back for takeoff after the airplane attained 55-60 knots. The airplane subsequently veered left off the runway despite application of full right rudder. The airplane’s left wing struck sage brush, which caused the airplane to cartwheel and nose over. The airplane sustained substantial damage to both wings, the vertical stabilizer, and the rudder. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
