A fatigue failure of the engine crankshaft, and an inadequate engine cylinder replacement by maintenance personnel. A factor in the accident was unsuitable terrain for a forced landing.

Read the full NTSB narrative
While in cruise flight at 3,000 feet MSL over remote terrain, the engine suddenly quit. The pilot selected a flat area for an emergency landing. After touchdown, the float assemblies were torn off the fuselage, and the airplane nosed over. During the postaccident examination of the engine, one cylinder bolt was found loose, and the engine case displayed evidence of fretting. The crankshaft was broken. A metallurgical examination of the crankshaft revealed a fracture pattern typical of fatigue cracking. The number one engine cylinder had been replaced about 585 service hours before the accident.
