Investigator assessment
Analysis narrative
The pilot of the amphibious airplane reported that he landed on a river uneventfully. After taxiing on the river for a while, he noticed that the wind had increased when he attempted to take off. As soon as the airplane lifted off from the water, it settled back down and violently turned 90°. The pilot added that there were no preimpact mechanical malfunctions or failures of the airplane that would have precluded normal operation and that he was able to taxi to a boat ramp after the impact with water. The airplane’s empennage was substantially damaged during the accident. The reported weather at an airport located 28 miles away from the accident site, about the time of the accident, included a left quartering headwind at 9 knots, gusting to 22 knots.
