Analysis

The pilot had just completed spraying a field and was climbing to return to his home airstrip when the engine failed. He landed in a nearby pasture but was unable to stop on the wet terrain before hitting a low fence. The main gear caught on the fence and the plane nosed over. A teardown of the engine revealed that the three blower bearings, pn 12768, had failed. Subsequently, the floating gear and idle gears were damaged.
