NTSB Narrative Summary Released at Completion of Accident

The solo airline transport pilot was making a local reconnaissance flight in a float-equipped airplane under 14 Code of Federal Regulations Part 91 in conjunction with a wilderness lodge business. The pilot said that he was scouting local lakes and rivers for fish and, while returning to a float pond near the lodge, the airplane's engine lost oil pressure and then lost power. The pilot said that he descended to a road, and that after he touched the floats on the road the left wing struck a tree, causing the airplane to depart the roadway. The airplane sustained damage to the left wing's leading edge and fuselage. A mechanic said that the number 8 cylinder separated from the engine, causing an oil line to separate.

NTSB Probable Cause Narrative

A total loss of engine power due to the separation of the number 8 cylinder from the engine, which separated an oil line, resulting in a loss of oil and oil pressure. Contributing to the accident was the float-equipped airplane's forced landing on a road.
