NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The float plane's takeoff roll seemed longer than normal to the pilot. After he lifted off, he noticed a shimmy even though the aircraft was out of the water. He decided to abort the takeoff because he "still had plenty of water left to land on" ahead of him. The airplane touched down with the left float first. When the right float touched down, the airplane yawed hard to the right and water looped. Water conditions at the time of the accident were reported by the pilot as calm. An examination of the wreckage revealed no pre-impact anomalies.

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

The pilot's failure to maintain control of the airplane, causing a water loop. A factor in the accident was the water loop encountered.
