What happened
The incident involved a floatplane operating out of the Ostrovnoye area. The aircraft attempted to depart from the Maly Anyuy River under conditions that included a light tailwind and a takeoff path against the water flow. During the rollout, the pilot encountered pebbles along the intended trajectory. To avoid striking these obstacles, the pilot decided to lift off earlier than planned while the airspeed was still below the optimal threshold for safe flight.
Immediately after leaving the water surface, the pilot began a turn. This maneuver caused the aircraft to lose aerodynamic efficiency and stall. The plane subsequently crashed back into the river. All six occupants on board sustained no injuries in the accident.
Findings
The official investigation concluded that the primary factor leading to the crash was the decision to initiate takeoff in unfavorable conditions. By lifting off prematurely with insufficient speed, the pilot created a situation where the aircraft stalled almost immediately after becoming airborne.
