NTSB narrative
The pilot was conducting an aerial application flight when the airplane’s left wing impacted a guy wire attached to a power line structure. The impact with the guy wire occurred while the airplane was flying along the edge of the field being sprayed. The outboard 7 ft of the left wing and the left aileron separated during the impact with the guy wire. The airplane subsequently crashed in a cornfield about 0.3 mile from the guy wire impact.
Examination of the airplane wreckage revealed no evidence of a preimpact malfunction that would have prevented its normal operation. A review of recorded engine monitor data revealed no evidence of an engine malfunction or failure during the flight. Day visual meteorological conditions existed, and the position of the sun at high noon would not have negatively affected the pilot’s view ahead of the airplane. The pilot’s autopsy and postmortem toxicology tests did not reveal any evidence of medical incapacitation or impairment.
Probable cause
The pilot’s failure to maintain clearance from a guy wire during an aerial application flight.

- 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, coordinates, 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.
