NTSB narrative

The operator reported that, during takeoff for an agricultural application flight, the airplane "quickly whipped" left almost immediately after becoming airborne. Subsequently, the airplane impacted a cornfield and then came to rest about 70 ft west of the runway.

Postaccident airframe examination did not reveal evidence of any preimpact anomalies with the flight control system that would have precluded normal operation. The pilot reported that there were no issues with the engine during the takeoff. The pilot added that he commonly used a gentle rise in the runway to assist the airplane to become airborne during takeoff; however, the investigation could not determine if this played a role in the loss of airplane control. Based on the available evidence, the investigation could not determine the reason for the pilot's loss of airplane control.

Probable cause

The pilot's loss of airplane control during takeoff for reasons that could not be determined because no anomalies consistent with a flight control system malfunction were observed.

  • 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. 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.
