Richmond Heights - Richmond Heights

The pilot had the waste gates on the turbocharges adjusted and wanted to test fly the airplane after the work was completed. The airplane departed and had reached an altitude of about 1,000 feet when witnesses heard an engine sputter. The airplane was seen making a left turn and enter a nose low, left spin before impacting the terrain. A tear down of the left engine revealed that the exhaust valves in cylinders #3 and #5 were burnt through at the valve head. The #5 exhaust valve had a deep preexisting deep mark on the valve stem. The failures of both valves were sufficient enough to cause a power failure in the left engine. The pilot, sole on board, was killed.
