On May 31, 2023, at about 1730 local time, a Grumman-Schweizer G-164B Ag-Cat Turbine, N8405K, was substantially damaged when it was involved in an accident near Saffell, Arkansas. The commercial pilot was not injured. The local aerial application flight originated from a private airstrip.

The pilot reported that shortly after takeoff on an aerial application flight to apply fertilizer to rice fields in a remote area the airplane unknowingly flew through a dust devil (also called a whirlwind), and subsequently lost lift.

The pilot estimated the dust devil was between 8 to 10 ft in diameter and reported no visible debris. The airplane subsequently impacted a dirt ditch, nosed over, and came to rest inverted. The pilot was able to egress from the airplane without further incident. The airplane sustained substantial damage to the engine mount, the fuselage, both wings, and the empennage.

The operator reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. The pilot reported that he had encountered several dust devils in earlier flights that day for the operating area. The pilot did not perform a hopper load dump during the accident sequence, as he reported flying the airplane was the priority. 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 after takeoff, which resulted in a loss of lift, and a subsequent loss of control. Contributing to the accident was the presence of a dust devil in the airplane’s flight path.
