Background
The aircraft was loaded beyond its maximum takeoff weight with extra fuel, camping equipment, a passenger, an outboard motor, and tools. The center of gravity was probably outside safe limits. The floatplane configuration was not approved, nor was the installation of a larger engine. A foldable boat was attached externally to the airframe, creating aerodynamic drag.
Accident Sequence
After takeoff, the pilot turned to land. During the turn, the aircraft stalled and descended into the water.
Pilot Information
The pilot was not floatplane-rated and did not hold a current medical certificate. The pilot's flight time was not reported or available.
