Analysis

Several witnesses viewed the acft circling over a bean field at an alt of 200 to 300 ft AGL. The plt and pax were reportedly looking for a radio-controlled airplane lost in the field. Witnesses continued to state an increase of power occurred and the acft began a climbing left turn during which the left wing dropped and the acft entered a spin. The acft crashed in the bean field 1/8 mile NE of the Oskaloosa aprt.
