Probable cause
Loss of airspeed and an inadvertent stall by the pilot during an attempted return to the airport, following a power loss due to carburetor ice.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The engine experienced a power loss due to carburetor ice about 5 minutes after takeoff at an altitude of 800 feet AGL and the pilot attempted to return to the airport for a landing. Realizing he would not make the airport, the pilot turned the airplane 90 degrees to the right and the airplane stalled at 30 feet and struck the road. On impact the pilot was thrown out, however he was not injured. The FAA examined the airplane and could find no indication of a mechanical failure. They reported the top spark plugs were sooty and the fuel tanks contained aviation gasoline.
