Read the full NTSB narrative
According to the sport pilot, during cruise flight in his experimental light sport airplane he noted that the two-cylinder engine's cylinder head and exhaust gas temperature gauges decreased in temperature. Thereafter, the number 1 cylinder (rear) stopped producing power, and engine power was partially lost. The pilot made a forced landing on upsloping, rough terrain. During landing, the airplane's forward fuselage buckled. The pilot said that examination of the engine revealed that the spark plug had come out of the engine's rear cylinder head. The pilot had changed the spark plugs about 2.5 hours prior to the mishap.
