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 took off on the aerial application flight, flew the helicopter about 1/4 mile to the assigned field, and completed an initial application pass. The pilot recalled that the helicopter was approaching the point at which he intended to reverse course for the next spray run; however, he did not recall the accident sequence. The accident site was located about 1/4 mile south of his planned turning point in an adjacent farm field. The pilot commented that the terrain was "flat" with corn about 8 feet tall. He also noted that the helicopter was "performing great" with no known problems before the accident. A postaccident examination did not reveal any anomalies consistent with a preimpact malfunction or failure.
