Analysis

After leveling at 2500 ft, oil fumes were noted, but no abnormal indications were noted on the engine gauges. The pilot suspected oil had been spilled during a repair before takeoff. A short time later, the engine RPM began to increase & was adjusted by the pilot. Subsequently, the engine failed. During a forced landing, the pilot was unable to reach a road & landed in a field. The main gear failed after hitting a ditch. The right wing was damaged after contacting the ground & the left wing hit a fence. An examination revealed there was oil along the left side of the fuselage. A hole was found in the engine case between the number 2 & 4 cylinders. The inlet oil line to the oil cooler had chafed against the exhaust stack & was leaking. It should have been routed under a heat shield & away from the exhaust stack. The oil line should have been a standard, medium pressure, stratoflex hose (MIL-H-8794D) reinforced with a fiber braids & a steel braid. The installed hose had a single fiber braid covering.
