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 stated that, before initiating the takeoff, he observed that the two windsocks located on the runway indicated a crosswind. Just after lifting off, the pilot felt a gust of wind from the left, and the airplane was pushed right toward a cornfield located next to the runway. The right wingtip impacted cornstalks, and the airplane nosed over and came to rest inverted in the field, which resulted in substantial damage to the fuselage and both wings. The pilot reported no preimpact mechanical malfunctions or anomalies with the airplane that would have precluded normal operation.
