During cruise flight in the homebuilt airplane, the pilot observed a rise in engine oil temperature. He elected to make a precautionary landing at a nearby airport; however, engine rpm decreased to where altitude could not be maintained. The pilot initiated a forced landing to a bean field about one mile northeast of the airport. During the landing, the airplane touched down hard, nosed over, and came to rest inverted. An examination of the Corvair automotive engine, by the owner, revealed a stuck oil cooler thermostat valve. The stuck valve was preventing oil from flowing through the oil cooler.
Probable Cause: the pilot's inadequate flare during the forced landing, which resulted in a hard landing. A contributing factor was the engine overheating due a stuck oil cooler thermostat valve, which resulted in a loss of power.
