Narrative:
During a cross-country flight, the pilot observed a significant increase in the engine oil pressure followed by a sudden drop. He prepared for an emergency landing during which the engine speed increased and the engine lost power. The cabin then filled with smoke and oil covered the windshield. The pilot was able to activate the airplane's parachute and the airplane landed about 5 seconds later in a ravine. The airplane was destroyed by a postcrash fire.
A postaccident examination of the engine revealed evidence of a pre-ignition/detonation event that partially eroded the Nos. 2 and 5 pistons. The eroded pistons permitted the pressurization of the crankcase, which resulted in oil starvation of the engine. Due to the severe fire damage, the cause of the preignition/detonation could not be determined.

Probable Cause: A total loss of engine power due to pre-ignition/detonation for reasons that could not be determined based on available information.
