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 maneuvering at low altitude over a field during an agricultural application flight, he was focused on the top of electrical poles that paralleled the field. He added that he crossed between the electrical poles and was focused on the pole to the right of the airplane. Once he crossed the top wire, he focused his attention forward, but added that he "was staring at a 30-ft tower just to the left of the nose" of the airplane. The airplane struck the tower and then impacted the ground. The airplane sustained substantial damage to the empennage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
