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.
