Flight and Incident Overview
A pilot reported that while cruising at 3,800 feet approximately 15 minutes after departure, the engine began to lose power. The pilot attempted an engine restart but was unsuccessful. Suspecting carburetor icing, the pilot initiated a forced landing onto a highway. During the landing, the aircraft departed the roadway and entered a ditch, after which it erupted in flames.
Weather and Environmental Conditions
The ambient temperature at the time was 38 degrees Fahrenheit, with a dew point of 33 degrees Fahrenheit. These conditions are considered conducive to the formation of induction system icing.
Engine Examination
A post-accident examination of the engine was conducted. No evidence of a mechanical malfunction was found during the inspection.
