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 reported that, while spraying a pasture at low altitude, the airplane struck a zipline cable, which resulted in substantial damage to the vertical stabilizer and rudder. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation and that he needed to be more alert to obstacles.
