Narrative:The airplane lost power on takeoff and landed hard during the ensuing emergency landing on a highway median. Upon examination of the engine it was noted that the forward spark plug had separated from the associated cylinder head. The cylinder head threads showed evidence of wear and appeared flattened. The pilot indicated that new spark plugs had been installed prior to the last flight and torqued to the manufacturer's recommended 110-inch pounds of pressure. He also stated that the threads on the cylinder heads are constructed of aluminum and the threaded portions of the spark plug barrels are constructed of steel. No further mechanical anomalies were noted.
Probable Cause: Separation of the forward spark plug due to wear damage to the cylinder head threads. A factor in the accident was traffic on the highway and the pilot having to maneuver to avoid the traffic.
