Incident Overview
A float-equipped airplane was departing from a river when the pilot encountered directional control difficulties. Two branches of another river were flowing from the right into the main channel used for departure. A left crosswind of 10 to 20 knots was present.
Takeoff Sequence
The takeoff run was toward the north. The pilot lowered the aircraft's nose to achieve the 'on-step' configuration and raised the water rudders. Shortly thereafter, the airplane began to veer to the left.
Pilot's Account
The pilot attributed the left turn to the combination of the left crosswind and a strong river current coming from the right. In response, he aborted the takeoff.
Collision
The airplane did not become airborne. It continued into shallow water and collided with trees along the left bank of the river.
Investigation
The investigation did not assign a probable cause to the event. No further details regarding the aircraft, operator, or occupants were provided in the source.
