NTSB narrative
The public-use airplane was being operated as a single-pilot aerial observation aircraft when it was responding to a ground fire. The fire originated from a garbage fire at a house that was adjacent to a wooded area. The wooded area was at the northern edge of a fallow agricultural field that the airplane was seen initially flying over on a southerly heading at an altitude of about 100 feet above the trees. The airplane then turned towards a northerly heading and descended to an altitude of about 35 feet above the field. The airplane engine noise then increased which was then followed by a wing drop consistent with an aerodynamic stall as it approached the tree line. Examination of the wreckage revealed no anomalies that would have precluded normal operation.
Probable cause
The pilot's failure to maintain adequate airspeed which resulted in an aerodynamic stall at a 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, damage. 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.
