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 entered the traffic pattern for runway 34 based on the prevailing wind. She observed the wind sock change to favor runway 16 and in response she maneuvered the airplane for a runway 16 landing. The wind changed direction again to favor runway 34 and she maneuvered the airplane to that runway. She thought the airplane was too high over the touchdown zone and elected to perform a go-around. The passenger in the right seat panicked and started screaming, so the pilot discontinued the go-around, closed the throttle, and the airplane settled into the trees past the runway’s end. The airplane sustained structural damage to the wings and fuselage. The pilot reported no preaccident mechanical anomalies with the airplane.

Factual narrative

The pilot entered the traffic pattern for runway 34 based on prevailing winds. She observed the wind sock change to favor runway 16, so she began to maneuver the airplane for a runway 16 landing. The winds again changed direction to favor runway 34. While on final approach for runway 34, she found herself too high over the touchdown zone, so she executed a go-around. A passenger in the right seat panicked and started screaming, so the pilot discontinued the go-around, closed the throttle, and the airplane settled into the trees past the runway end. Structural damage to the wings and fuselage resulted. The pilot reported no mechanical anomalies with the airplane.
