Aircraft Accident/Incident Report

Venice, Louisiana 70764
Wednesday, August 12, 1998 13:00 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot lost control of the amphibian airplane during a 'high speed step-taxi' after landing. The pilot noticed a swell left by a boat that had departed the landing area and elected to approach the swell at a 45 degree angle. As the airplane crossed the swell, the pilot felt the right float 'dig in.' In an effort to prevent the floats from sinking further, the pilot pulled full aft on the yoke and applied full power. The airplane nosed over inverted and began to sink.

NTSB Probable Cause Narrative

The pilot's failure to maintain control of the airplane during high speed step-taxi. A factor was the swell left by the boat.
