Read the full NTSB narrative

The commercial certificated pilot was on a cross-country positioning flight under Title 14, CFR Part 91, in a float-equipped airplane, when the number 6 engine cylinder separated from the engine through the engine cowling. The pilot made a hard emergency landing in steep ocean swells, and was able to beach the airplane. The airplane received structural damage to the wings and fuselage during the landing. An examination of the eight studs holding the number 6 cylinder to the engine case, revealed they were either broken or their threads were stripped. An examination of maintenance logbooks did not reveal any unresolved preaccident mechanical anomalies.
