Analysis

The acft made a forced landing in a field of rye grass after the engine lost power. Investigation revealed that a connecting rod had failed. An FAA inspection revealed that the connecting rod retaining bolts were not properly torqued during a recent major overhaul. The owner did not file a 6120.1 report because this was not an 'accident'.
