NTSB narrative
The pilot reported that he was completing an aerial application flight over a cultivated field. During the fourth pass, the airplane encountered a dust devil (also called a whirlwind), lost lift and impacted powerlines. Upon impact with the powerlines the rudder separated from the airplane and the airplane began a left turn. Unable to arrest the turn, the pilot reduced power and made a forced landing to the field that he was spraying. Upon touch down the left main landing gear separated from the fuselage and the airplane slid to a stop. The airplane sustained substantial damage to the left wing, vertical stabilizer and rudder. The operator reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. A review of the Federal Aviation Administration Aviation (FAA) Weather Handbook (FAA-H-8083-28) and the FAA Aeronautical Information Manual found no detailed information listed about dust devils or the potential hazards of flying through dust devils.
Probable cause
The airplane’s encounter with a dust devil, which resulted in a loss of lift, and subsequent collision with powerlines.

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.
