Accident Overview
During takeoff on Runway 27, the aircraft was observed in a slow-speed, nose-high climb. Witnesses reported that the engine power was interrupted momentarily, then restored. Shortly thereafter, the aircraft rolled to the right, entered a descent from approximately 200 feet above ground level, and crashed in a steep nose-down attitude.
Witness Observations
Witnesses stated that the aircraft climbed in a nose-high attitude at slow speed. The engine power interruption was brief, and power was regained, but the subsequent roll and descent led to the crash.
Aircraft Weight and Balance
No weight and balance information was available in the aircraft's logs. Using the weight and balance data from the time of manufacture, corrected for the installation of fuel tanks, the aircraft was estimated to be 68 pounds over its maximum gross weight limit.
Engine and Fuel System
No preimpact mechanical failure was found in the engine. The aircraft had been serviced with auto fuel, but no supplemental type certificate (STC) had been approved for such fuel. Additionally, the carburetor heat was found in the cold or off position. According to icing probability charts, serious carburetor icing could have occurred at glide power given the temperature and dew point conditions.
Environmental Conditions
The wind was from 060 degrees at 12 knots, gusting to 23 knots. Density altitude was 2,100 feet. The temperature was 89°F and the dew point was 68°F.
