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 said he was taxiing to runway 19 for departure. The reported winds were from 190 degrees at 18 knots gusting to 26 knots. The pilot taxied to the end of the runway after performing all the preflight checks and he turned to a downwind direction to check for landing traffic. As the airplane turned, the right wing began to rise and the airplane nosed over, bending and wrinkling both wings, the empennage, and the rudder.
