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 had just purchased the airplane and was receiving flight instruction to satisfy insurance requirements. They decided to fly to the instructor's home and land in a field behind his house. They made a low pass and noted that there was a slight ditch with some water in it about halfway down the field. They landed beyond the ditch and the pilot noticed some trees at the end of the field that were getting closer. The pilot believed the tail was still flying when he applied slight braking to slow down. The airplane struck a bump, or bounced, and nosed over, causing substantial damage to both wings, the vertical stabilizer and rudder, the engine, and the propeller. The pilot reported no mechanical malfunction or failure with the airplane.
