Analysis

The acft was observed in a high speed glide to touch down briefly in a pasture at the top of a knoll. It then dropped below the rise & crashed in a wooded area adjacent to the pasture. Examination of the eng showed a crack extending from the top forward hold-down bolt on the right front cylinder through the push rod opening to the top of the crankcase. The top forward hold-down bolt was sheared off & came loose when touched. There was also a crack on the left side extending from approximately 1 inch aft of the front cylinder hold-down bolt upward between the push rod housings to the top of the crankcase. Tear down of the eng revealed the oil pump drive gear failed.
