NTSB narrative
The pilot stated that he initiated the takeoff with a '... strong quartering tailwind.' According to the pilot he was taking off to the east with the local winds from 315 degrees at 15 to 20 knots. He reported that the airplane veered to the left and he was unable to compensate for the veer using the rudder. The airplane traveled off the left side of the airstrip and through a rice field where it contacted a levee knocking off the main gear. The pilot stated he started flying at 0700 central daylight time and he had flown 24 loads on the day of the accident.
Probable cause
the pilot selecting the wrong runway direction on which to initiate the takeoff and his failure to maintain directional control. Factors associated with the accident were the quartering tailwind condition, the rough terrain encountered, and fatigue.

- 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.
