Probable cause

The pilot's inadequate compensation for wind conditions and failure to maintain an adequate airspeed, resulting in a stall/mush. Contributing to the accident was the gusty crosswind conditions.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

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 that he departed from runway 25 during gusty wind conditions. At 800 feet above ground level, he turned the airplane onto the crosswind leg and the left wing went down. The pilot recovered the airplane, added full throttle, and the airplane continued to descend. The pilot pulled back on the yoke to make the airplane climb; however, the airplane continued to descend. The airplane impacted trees and sustained substantial damage. According to the nearest aviation weather reporting system that was located at the airport, winds were from 290 degrees at 16 knots, gusting to 21 knots. The Federal Aviation Administration inspector examined the airplane and found no mechanical anomalies that would have resulted in a loss of airplane control.
