Higginson, AR, USA
N779EF
GRUMMAN G164
The airplane was departing the local airstrip to perform an aerial application. About 50 feet above ground level, the pilot noticed a partial loss of engine power and felt a vibration from the engine. The pilot performed a forced landing in a wheat field, and a postimpact fire ensued, which consumed the airplane. Based on his observations during the engine failure, the pilot suspected a cylinder or magneto failure. However, the engine was not disassembled for further examination and the cause of the partial loss of engine power was not determined.
