Factual Information

On Friday, February 24, 1995 about 1215 eastern standard time, a Beech 35, N3344V, piloted by Miguel Angel Iturmendi, was substantially damaged during a forced landing in Shadyside, Ohio. The pilot received minor injuries. The ferry flight from Columbus, Ohio to Wheeling, West Virginia was being conducted under 14 CFR Part 91. The pilot reported, during cruise flight about 10 miles from Wheeling, he noticed the oil quantity gauge was indicating a low oil quantity. The pilot then observed white smoke entering the cockpit and a loss of engine power. He saw a field off the right wing and attempted to go there for a forced landing. While approaching the field, the pilot determined the airplane would not reach the field and decided to stall the airplane on top of some trees in a wooded area. The engine was inspected by Clydesdale Aircraft Corporation under the supervision of the Federal Aviation Administration. Post accident examination revealed, "...The number six connecting rod failed due to loss of lubrication and the resultant build up of heat which melted the rod bearing and rod bolts, causing the rod to be forced through the crankcase." There was no oil found in the engine throughout the examination.

Probable Cause and Findings

The loss of oil pressure, which resulted in the number six connecting rod failure and penetration through the crankcase.
