What happened
The pilot attempted to take off from a remote lake during periods of gusty and turbulent wind. The aircraft was carrying six people, despite only having four seats and four seat belts available. During the takeoff roll, witnesses observed the airplane being pulled off the water abruptly, climbing at a steep attitude until reaching approximately 20 feet above ground level (AGL). At that altitude, the aircraft struck the water forcefully with its right float, causing the plane to turn upside down.
Following the impact, rescuers—including a lodge owner and a pilot who is also a physician—reached the scene. They successfully administered CPR to an unconscious adult female and a male juvenile who were not breathing.
