NTSB narrative
After receiving a weather briefing that indicated a probability of en route icing conditions, the pilot, who was not instrument rated, filed an instrument flight rules flight plan through those conditions. The airplane was not approved for known icing conditions. While en route, the pilot advised air traffic control that the airplane had encountered icing, and requested a lower altitude. The controller approved a descent to the lowest altitude permitted by terrain clearance requirements. After contacting the next en route controller, the pilot again noted icing, and again requested a lower altitude; however, the controller could not approve a further descent due to the same terrain clearance requirements, but authorized a turn. Subsequently, based upon information from another pilot, the controller advised the pilot that he could climb to try to exit the top of the clouds, which the pilot accepted. The airplane began a climb, but the pilot then radioed, "we're going down." When requested by the controller, the pilot confirmed that the airplane was again accumulating ice. Postcrash examination of the airplane revealed no mechanical anomalies, and its trajectory through the trees was consistent with a stall/spin.
Probable cause
The pilot's improper decision to take off in conditions conducive to icing, and his inability to maintain control of the airplane during an in-flight accumulation of structural ice.

- 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.
