Analysis

The pvt plt had been giving rides around the local area for about an hour. He had just dropped off one passenger and picked up another. The acft taxied from the ramp to the rwy 30 and made a normal takeoff. During crosswind turn the engine started to miss and back fire. The acft made the downwind turn at about 400 ft AGL and a curving base to final. The acft stalled and crashed. Witnesses reported strong gusty winds east and south of the airport. Evidence suggests the engine was not operating at impact; however, post accident exam failed to disclose any failure/ malfunction. The acft was destroyed by post impact fire. Atmospheric conditions were conducive to carburetor ice at the time of the accident.
