NTSB narrative
The airplane was performing an aerial application flight when it impacted the ground while making a turn at the end of a spray pass. Witnesses to the accident reported that they saw the aircraft making a turn at the end of northbound pass. One of the witnesses reported that during the turn, "...the left wing dropped, nose went down, and the aircraft spun to the left." A second witness reported that, "...in the middle of the turn about that the plane seemed to be turning a little to[o] sharp. He was flying north turning to the west when about halfway is when it dipped real bad and made about 3/4 of a revolution and came nose first into the ground." The witness also stated that he did not hear a difference in engine sound when the accident occurred. A third witness reported that the aircraft, "...turned right then left at about 2/3 of the way around the plane seemed to turn real sharp then turned over and spiraled to the ground. A fourth witness reported that the aircraft was, "...spraying from south to north, and was in the process of making a turn to his left and was starting to come out of the turn when the plane started to roll or spin down. I could hear the engine thru out the spraying process and the sound of the engine never seem[ed] to change thru out this period." A postaccident examination of the aircraft did not reveal any anomalies that could be associated with a preexisting condition.
Probable cause
The inadvertent stall/spin encountered by the pilot. A factor was the low altitude.

- 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.
