NTSB Narrative Summary Released at Completion of Accident
The private pilot of the float-equipped airplane was taking off from a municipal float plane lake. He said during the takeoff roll the airplane did not accelerate as fast as normal, and once on step did not accelerate as anticipated. He aborted the takeoff, but the airplane would not stop in the remaining length of the lake. The pilot said he elected to hit the bank head-on rather than in a turn. The airplane traveled onshore 20-30 feet before nosing over. The pilot said when he exited the inverted airplane, the left float was draining what he thought was an excessive amount of water. He said he pumped the floats prior to departure, but felt that a leaking gasket may have filled the left float with water during the pretakeoff water taxi. An FAA air safety inspector who interviewed the pilot, said the pilot told him he had inadvertently left the flaps in the 40 degrees extended position during the takeoff roll. The airplane was not examined by the NTSB.
NTSB Probable Cause Narrative
The pilot's excessive flap setting during takeoff.
