Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot was conducting a cross-country flight when, about 20 minutes from the destination airport, the engine lost partial power. The pilot switched fuel tanks, turned on the fuel pump and carburetor heat, and reduced engine power. The engine subsequently lost total power and the pilot performed a forced landing to a highway. During landing, the right wing impacted a light pole and the airplane nosed over and came to rest inverted. A postimpact fire ensued and consumed a majority of the airplane. Both fuel tanks were breached and thermally damaged. The fuel selector was not located. Examination of the engine revealed no evidence of preimpact mechanical malfunctions or anomalies. Compression was obtained on each cylinder when the engine was rotated by hand at the crankshaft. The carburetor was intact and free of debris. The electric fuel pump was operational. The single-drive magneto was impact damaged, but produced spark at each of the 12 leads. Based on the available information, the reason for the loss of engine power could not be determined.
