What happened
During an approach and landing maneuver near Cape Ashizuri, a seaplane encountered a mechanical failure. As the aircraft touched down on the water, one of its floats detached from the airframe. The impact or the force of the landing caused the component to separate, forcing the aircraft to come to a halt.
Despite the structural damage sustained during the landing phase, the incident did not result in any loss of life. There were 0 fatalities and no reported injuries among the occupants. The aircraft remained afloat following the separation of the float until it reached a stationary position.
Findings
The primary factor in this occurrence was the loss of a float during the landing sequence, which led to the vessel coming to rest.
