NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

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.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

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.
