NTSB Narrative Summary Released at Completion of Accident

The experimental amateur-built airplane impacted a lake during a forced landing. The reported damage to the engine's components were consistent with oil starvation. The pilot was also the manufacturer and owner of the airplane. The pilot stated that the engine accumulated a total time since new of about 125 hours. The engine was never overhauled since it was purchased by the pilot in 1969. The engine manufacturer’s service instruction states that the engine is to be overhauled in the twelfth year if it does not accumulate the hourly period of time between overhauls.

NTSB Probable Cause Narrative

Engine oil starvation and inadequate maintenance by the pilot.
