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 conducting an agricultural application flight, he misjudged the height of the power wires, and as a result, the airplane's right wing struck the lower wire. The airplane subsequently impacted the ground and rolled several times before coming to a stop, and a fire ensued. The airplane was destroyed by postaccident fire. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
