NTSB narrative
The pilot indicated that, during the cross-country flight, the engine "sputtered" several times then regained power. During the descent, it sputtered again and then lost power. The pilot reported she did not believe she was experiencing carburetor icing conditions during the cruise portion of the flight and did not remember what temperature the carburetor temperature gauge was displaying at the time. During the descent, the pilot attempted to troubleshoot the engine power loss without applying carburetor heat but was not successful in regaining engine power. During the forced landing, she attempted to maneuver the airplane between a power line pole and several trees. The airplane struck the power lines and impacted a field in a slightly nose-down attitude, which resulted in substantial damage to the wings and fuselage.
Postaccident examination of the airplane and engine revealed no mechanical malfunctions or failures that would have precluded normal operation. The airplane had adequate fuel on board to complete the flight. The weather conditions at the time of the accident were conducive to serious carburetor icing at glide power settings. The loss of engine power likely occurred due to carburetor icing and the pilot's failure to apply carburetor heat in conditions conducive to carburetor icing.
Probable cause
Loss of engine power due to carburetor icing and the pilot's failure to use carburetor heat in weather conditions conducive to carburetor icing.

- 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.
