What happened
During a flight near False Pass, a seaplane performed an emergency landing on the surface of the water. During the process of ditching, the aircraft likely struck an underwater object, which caused the nose of the plane to dip downward into the water.
The impact resulted in the aircraft settling on the floor of the water body at a depth of approximately 110 feet. Despite the severity of the descent, all four occupants managed to exit the cabin successfully before the vessel submerged.
Findings
Preliminary assessments suggest that the primary reason for the loss of control during the landing was the impact with a submerged object. This collision caused the aircraft to lose its upright orientation and sink rapidly.
