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 in a left turn during an aerial application flight the airplane encountered a gust of wind and began to "shake", so he leveled the wings momentarily before continuing the turn. He further reported that he was looking at the field instead of where he was turning and when the airplane was 30-50 feet above the ground he looked up and saw electrical wires. The right wing tip struck the electrical wires and the airplane made a forced landing in a nearby pond. The airplane sustained substantial damage to the both wings and fuselage. The pilot also reported that during the day of the accident he was under stress and his head was "in another place". The pilot reported that there were no preaccident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
