Analysis

The commercial ag plt was starting a spray run on a new field. During the first pass, the aircraft struck power line wires. The aircraft rolled left and impacted the terrain in a wings level, nose low attitude. An immediate post crash fire destroyed the aircraft. The plt was fatally injured. The plt was familiar with the local area, however there is no evidence to indicate that he had surveyed this particular field prior to beginning operations. Evidence and witness statements indicate that the decision to begin the new field was made solely on the basis of having enough chemical left for about two more passes. Witness statements indicate that the acft pulled up in an attempt to avoid the wires, but the attempt failed. Wire impact damaged the left wing main struts and both left wings failed prior to impact, according to a witness' statement.
