NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
As the private pilot-rated student was climbing through 400 feet above the water in the float-equipped airplane, the instructor pilot pulled the power to idle and instructed the student to execute a simulated engine-out forced landing on the waters of a bay. The student then established the aircraft in a controlled slip in order to descend to the point at which he wanted to touch down. When the aircraft was about 50 feet above the water, and still in a slip, the instructor, who had just warned the student to watch the airspeed, thought that the aircraft was about to enter a stall. In order to keep the aircraft from entering the stall, the instructor added full power and pushed forward on the control stick. The aircraft then pitched down and impacted the surface of the water in a 30 to 40 degree nose-down attitude. It was the opinion of the student that the aircraft was not about to enter a stall, but that the instructor pilot misinterpreted some light turbulence, and the wing-low attitude created by the slip, as the beginning of a stall.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The instructor pilot's inadequate remedial action during his student's final approach for a simulated engine out water landing. Full narrative available
