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 agricultural application pilot reported that, during the initial climb and as soon as the airplane "broke ground," he turned left and subsequently encountered turbulence that caused the left wing to "dip." He added that he applied full right aileron and rudder but that the airplane continued to sink and turn left. Subsequently, the left wing impacted terrain, the airplane cartwheeled, and a postcrash fire ensued. The fuselage, empennage, and both wings sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. An automated weather observation station, 12 nautical miles south of the accident site, reported, about the time of the accident, calm wind, clear skies, temperature 84°F (29°C), and dew point 64°F (18°C).
