During cruise flight, the engine lost power and the airplane struck a car and then the right wing hit a fence during a forced landing on a freeway. The pilot had rented the airplane for a personal flight. There were no mechanical malfunctions noted on the first leg of the flight. On the second leg of the flight, the pilot noted a drop in engine power followed by a violent shaking of the airframe. The pilot set up for an emergency landing on the freeway. During landing, the airplane impacted a car, which the pilot had not noticed, and a fence. Post accident examination disclosed that oil covered the belly of the airplane and coated the inside of the engine compartment and nose wheel assembly. The engine sustained a catastrophic internal failure. The oil drain plug was missing. The investigation revealed that the engine had been overhauled 5 hours prior to the accident and then reinstalled by the operator's maintenance personnel. The oil drain plug is normally secured with safety wire. No safety wire remnants were found on the engine.
Probable Cause: Failure of company maintenance personnel to correctly install and safety wire the oil drain plug, which led to a loss of engine oil and a catastrophic internal failure of the engine.
