Descent and Power Loss
During a normal descent in preparation for landing, the engine lost all power. The pilot executed an emergency landing. However, during the landing rollout, the nosewheel encountered soft, uneven terrain, and the aircraft nosed over.
Fuel and Engine Examination
No fuel was found in the fuel tanks or the carburetor float bowl. Vegetation located below the vented fuel caps was discolored, indicating that fuel had drained out. When the engine was examined, no reason for the power loss was found. Due to damage sustained in the accident, an engine run-up was not attempted.
Carburetor Icing Considerations
The temperature and dew point were 69°F and 61°F, respectively. According to icing probability charts, serious carburetor icing could have occurred at glide power. The carburetor air box was damaged during the accident; therefore, its preimpact condition could not be determined. The carburetor heat control was found in the 'ON' position.
