NTSB narrative
The commercial pilot of the experimental airplane reported that he was unable to enter the destination airport airspace, so he remained outside of the airspace at a reduced power setting. After adjusting the mixture control, the engine experienced a complete loss of power and the propeller stopped rotating. About 1,600 ft above ground level (agl), the pilot initiated a steep dive to increase airspeed and attempt to get the propeller to windmill and the engine to restart; however, the propeller would not rotate, so he pulled out of the dive about 300 ft agl and aligned with traffic on an interstate for a forced landing. During the landing, the right wing contacted a truck and the airplane sustained substantial damage to the wings and fuselage. A postaccident engine test run revealed no anomalies, and the test was unable to determine why the propeller would not windmill above the published speed. The atmospheric conditions at the time of the accident were conducive to the accumulation of carburetor icing at glide and cruise power settings. The pilot did not use the carburetor heat during the reduced engine power operation; therefore, it is likely that the carburetor accumulated ice, which resulted in the total loss of engine power.
Probable cause
The pilot's failure to use carburetor heat while operating at low power settings in conditions conducive to the development of carburetor ice, and the subsequent total loss of engine power due 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, coordinates. 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.
