The NTSB's narrative final · quoted from the NTSB record

The pilot and pilot-rated passenger departed Grand Canyon National Park Airport after a fuel stop in Las Vegas, Nevada. About 30 minutes into the flight the pilot noticed a low oil pressure indication and declared an emergency. Moments later the engine sustained a total power loss and the engine seized. When it became evident the airplane could not make it to the airport, the pilot made the decision to ditch the airplane into a nearby lake. The airplane was substantially damaged during the water landing. Postaccident examination of the engine revealed discoloration of the cylinder and bearing surfaces consistent with high heat signatures due to oil starvation. The engine examination revealed no preimpact mechanical anomalies except for the oil filter adapter housing, which was loose, and the gasket was torn and deformed. As the oil level was likely normal at the pilot’s previous stop and the pilot did not notice any unusual reductions in oil quantity during the service life of the engine, it is likely that the oil started to leak during the accident flight. The failure of the gasket likely allowed engine oil to exit the crankcase rapidly, resulting in oil starvation and the subsequent catastrophic failure. A review of the engine maintenance records revealed no entries that the oil filter gasket had been inspected in accordance with the mandatory service bulletin, nor was it required.
