Probable cause
A failure of an engine cylinder exhaust valve due to the buildup of lead deposits on the valve stem and fatigue cracking of the valve stem, resulting in a total loss of engine power, and the loss of the propeller. Contributing to the accident was the lack of design standards or guidance for assembly and maintenance of light sport aircraft.
