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 was performing aerial application of liquid fertilizer onto a hay meadow. During the third pass, which was south of the previous two passes, the airplane contacted an unmarked power line that the pilot did not observe until "I was on it." The airplane then struck two trees and cart wheeled into terrain.

Factual narrative

The pilot was performing aerial application of liquid fertilizer onto a hay meadow. During the third pass, which was south of the previous two passes, the airplane contacted an unmarked power line that the pilot did not observe until "I was on it." The airplane then struck two trees and cart wheeled into terrain. The commercial pilot, who was the sole occupant, sustained minor injuries. Examination of the airplane showed the wings were bent, fuselage was twisted and buckled, and the engine firewall was buckled.
