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, who was on a local personal flight, decided to make an off-airport landing in an open field. Although the touchdown in the tailwheel-equipped airplane was uneventful, the pilot applied hard braking in order to minimize the landing roll on the rough terrain. As the airplane began to slow it nosed over onto its back. Both the wings and the fuselage sustained substantial damage. The pilot reported that there were no mechanical problems with the airplane's systems.
