NTSB Narrative Summary Released at Completion of Accident

The single-engine experimental airplane collided with sagebrush growing on an abandoned airport during a forced landing following a loss of engine power. The amateur-built airplane utilized a Honda EB-3 engine that was mounted at the rear of the airplane. Post-accident examination of the engine revealed the number 4 connecting rod had failed, and was discolored black, indicative of an overheating. The crankshaft throw for the number 4 connecting rod was also discolored black. No obstructions or anomalies with the lubrication system could be found.

NTSB Probable Cause Narrative

The overheating and failure of the number 4 connecting rod, which resulted in a total loss of engine power during descent.
