Analysis

While in cruise flight in VFR conditions and on an IFR flight plan, the pilot experienced a total loss of engine power. The pilot executed a forced landing in a soy bean field after an unsuccessful restart attempt. Examination of the oil cooler hose revealed a hole chafed through it at the point where it was routed under the cabin heat air duct hose; this hole allowed the oil to vent overboard. The engine seized due to oil exhaustion.
