Analysis
During a local dual instructional flight, the pilot reported that the aircraft developed a vibration and a substantial power loss. The acft was forced to land off the arpt in the high vegetation. Examination of the aircraft revealed that the #3 cylinder was not developing compression. The propeller was rotated and the piston would not respond. The #3 cylinder assembly and piston were removed and found that the connecting rod bearing was badly scored with no apparent lubrication visible. One connecting rod bolt was found sheared. A sample of oil was analyzed and found to contain a slightly high content of dirt. A high content of aluminum and copper were also noted.
