Incident Overview
The pilot departed DuPage Airport in Chicago, Illinois, en route to Kansas City Downtown Airport. During descent from cruise altitude, the pilot reported that oil covered the windscreen and engine power was lost. The pilot attempted a night forced landing at an airport located approximately 45 miles northeast of the intended destination.
Loss of Control and Runway Excursion
During the landing roll, directional control of the aircraft was lost. The aircraft careened off the hard-surfaced runway into rough and uneven terrain, which tore a wing from its attachment point.
Post-Accident Examination
A post-accident examination of the aircraft and its records revealed that it had not been properly inspected and was not airworthy for the flight. The engine failure appeared to be indicative of a connecting rod, rod end, or rod bolt failure, with a resultant hole in the engine case.
