Probable cause

A partial loss of engine power during initial climb due to a cracked cylinder.

NTSB narrative

The pilot reported after a normal takeoff in a float-equipped airplane, about treetop height, there was a loud bang and pulsing sensation, and the engine lost partial power. Unable to maintain altitude and return to the airport, the pilot performed a forced landing to the mud flats. The airplane sustained substantial damage to the elevator and horizontal stabilizer. Postaccident examination revealed the No. 9 cylinder was cracked. The last maintenance performed was about 90 hours before the accident, there were no anomalies noted at that time.
