Shortly after leveling off at a cruise altitude of 8,500 feet mean sea level, the pilot noted that the engine rpm increased to above its red line limit (2,700 rpm). The pilot was able to reduce power to 2,500 rpm but was unable to restore thrust and maintain altitude, so he made a forced landing in a nearby wheat field. During postaccident examination, the engine turbocharger controller was found covered with oil. Examination of an elbow fitting on the turbocharger wastegate control revealed that an O-ring was improperly installed and flattened, which allowed oil to seep out. When the O-ring was reseated and the elbow fitting torqued, no seepage was observed.
Probable Cause: The improper installation of the wastegate controller O-ring, which resulted in a partial loss of engine power.
