The pilot stated that he forgot to add engine oil during an oil change he performed on the airplane before the flight.
He said he forgot to add the oil because he was rushed and had personal activities to perform.
Examination of the airplane confirmed engine oil starvation.
A post-accident examination of the airplane revealed no other mechanical anomalies that would have precluded airplane operation.
