| Confidence Rating: |  Accident investigation report completed and information captured |
The student pilot reported that during his first solo cross-country flight, the weather started to deteriorate. He descended to a lower altitude to avoid clouds and proceeded toward the nearest airport. However, when he tried to level off at the lower altitude, the airplane continued to descend at a rate of about 700 feet per minute. The pilot applied full engine power and ensured that the throttle was positioned for full power, the mixture was full rich, and the fuel selector was on both fuel tanks. The airplane continued to descend, so the pilot elected to land on a nearby road. While on the base leg for the landing, the pilot applied carburetor heat. During the landing flare, the left wing struck a road sign; the airplane departed the road and came to rest inverted about 20 feet from the road. A postaccident examination and engine run revealed no mechanical failures or malfunctions that would have precluded normal operation. The weather conditions at the time of the accident were conducive for serious icing at cruise power settings. It is likely that the student pilot's delayed action in applying carburetor heat resulted in a partial loss of engine power due to carburetor icing.
Probable Cause: A partial loss of engine power after a descent to a lower altitude due to the student pilot's delayed action in applying carburetor heat while operating in conditions conducive to carburetor icing.
