Aircraft Accident/Incident Report

Lake Shasta, California 96051
Saturday, May 12, 2001 19:40 PDT

NTSB Narrative Summary Released at Completion of Accident

At the conclusion of a 30-minute-long flight, the pilot encountered light to moderate turbulence on approach to the lake in his experimental seaplane. About 50 feet above the water, he experienced a strong downdraft and applied engine power to decrease his 1,000-foot-per-minute descent rate. Suddenly, the airplane pitched downward and impacted the water. Thirty-knot wind gusts were subsequently noted in the area.

NTSB Probable Cause Narrative

A loss of control on final approach due to encountering a strong wind gust and downdraft.
