NTSB Narrative Summary Released at Completion of Accident

According to the pilot, he made a pass over the lake in search of a landing site with the least amount of boat traffic. After an uneventful water landing, he began to water taxi the airplane; however, his passenger and he noticed a large wave approaching at a 45 degree angle from the port side of the airplane. As the wave impacted the airplane’s pontoons, the pilot encountered a strong left rudder deflection and the airplane nosed over into the water. A postaccident examination by a Federal Aviation Administration inspector revealed substantial damage to the airplane’s nose section. The pilot reported no preaccident mechanical malfunctions or failures of the airplane that would have precluded normal operation.

NTSB Probable Cause Narrative

An encounter with a large wave during water taxi, which resulted in the airplane nosing over.
