Analysis

A forced landing was made north of the arpt. A post accident tear down of the engine revealed a failure of the #1 connecting rod end cap. This and parts of the piston ring sections and a connecting rod bearing were found in the oil sump. #2 cylinder was found battered and dented. #3 and #4 cylinders were normal.
