Analysis

The acft was level, in cruise when the plt noticed high eng temperatures. He stated that he started a shallow climb and headed for the nearest arpt. En route to nearest arpt, smoke came into the cockpit and the plt heard a loud noise that was accompanied by smoke and flames inside the eng compartment. Plt shut off fuel valve. The acft was too high and too fast as it approached the arpt. The plt tried s turns but ran out of control during the second s. the acft touched down 100 ft to the west of the rwy and 40 degs off the rwy heading. The right wing hit steel fence posts and barbed wire. After ground impact the acft flipped up and around and stopped on the arpt property. Investigation revealed a broken piston, a broken piston pin and a separated cylinder head on the number four cylinder.
