Analysis

While over a wooded area at 800 ft AGL the eng failed. The plt was unable to reach a suitable landing site before contacting the ground on an embankment below the elevation of a nearby road. The acft struck a telephone cable prior to touchdown. The #4 conrod was found broken near the inboard end (rough granular fracture) & was broken at the outboard end. The piston wrist pin was disintegrated. The piston pin boss was broken on one end. Chunks & metal shavings were found throughout the eng. There was no evidence of oil starvation. The eng was last overhauled in 1973, 124 tach hours prior to the accident, & all pistons were new. The acft had operated 4 hrs since the last annual on 9/9/82 & only 7 hrs since the previous annual on 7/81.
