The pilot reported that he was about 1/4 mile from the airport at 50 feet in the initial climb, when the engine began a severe vibration, then it stopped, abruptly. The pilot selected the only available landing area, which was a muddy field, and the aircraft nosed over during the landing ground roll. Preliminary examination of the engine revealed that the crankshaft was seized and would not move. Partial disassembly of the engine revealed that it had sustained a catastrophic internal failure. The No. 5 piston (master) was found out of it's respective cylinder, with the connecting rod elongated and bent. The rod end cap was attached on one side and separated on the other. Evidence of heat and stretching was observed near the crankpin area of the rod. The bearing could not be examined due to internal damage of the engine.
