NTSB narrative
The pilot flew the agricultural airplane to the designated spray area. He made 3-4 passes on a corn field and surveyed the area for guy-wires (a tower was adjacent to the field). He flew multiple passes around the tower to look for guy-wires but he was not able to get an exact location on the tower’s guy-wires and started spraying the field from south to north, and then west to east. After spraying about 4 passes in the middle of the field and 3 passes on the west end of the field the airplane struck a guy-wire with the right wing. After the airplane hit the wire, the pilot had trouble maintaining altitude. The airplane collided through a single set of power lines and struck the ground, resulting in substantial damage to the wings, fuselage, and empennage.
Probable cause
The pilot’s failure to maintain clearance from guy-wires during low-altitude agricultural operations.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
