Narrative:The pilot descended from 5,500 feet to 1,500 feet, at a moderate cruise power setting, at 5,500 rpm. About 1,500 feet above the ground, the two cycle 2-cylinder engine lost all power, and the pilot performed a forced landing to a field. The pilot believed that the descent at cruise power created a lean fuel/air mixture. Examination of the engine revealed scoring on both pistons, which was directly in line with the exhaust. According to a representative from the engine manufacturer, that type of failure was indicative of a heat seizure, normally associated with an excessive exhaust gas temperature, exceeding 1200 degrees F. The representative assumed that the engine was operating in a lean condition. According to the manufacturer's engine manual, during cruise and descents, it was very important that to avoid creating a lean mixture condition with high rpm and low throttle opening. Additionally, the manual warned that the engine was subject to sudden stoppage, and conformed to no aircraft standards.
Probable Cause: The pilot's failure to follow the engine manufacturer's descent procedure, which resulted in a lean mixture condition and subsequent engine seizure.
