Accident Sequence
According to the pilot's report, the accident occurred during the departure of a float-equipped airplane in strong gusty wind conditions. After accelerating on the water for approximately three seconds, the airplane unexpectedly became airborne. It then crabbed into the wind, deviating about 60 to 90 degrees from the intended takeoff path. As the climb continued, the airplane stalled and impacted the water in a nose-low attitude. The impact caused substantial damage to the wings and fuselage.
Pilot Report
The pilot stated that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation. The takeoff was initiated in strong gusty wind conditions, which the pilot described as challenging.
Probable Cause
The official probable cause determined by the investigation is the pilot's failure to maintain directional control during takeoff in gusting wind conditions, which resulted in the wing exceeding its critical angle of attack, leading to a loss of control and subsequent impact with the water.
