What happened
Following a landing on the surface of Lake Donuzlav, an unidentified floating object struck the aircraft. The impact caused the pilot to lose control of the vessel, leading to the subsequent sinking of the plane.
During the accident, there were four people on board the aircraft. The incident resulted in three fatalities, while one remaining occupant was successfully rescued from the scene.
Findings
Official investigations concluded that the primary reason for the loss of control and the sinking of the aircraft was a collision with an unidentified object floating on the water's surface immediately after the landing phase.
