The NTSB's narrative final · quoted from the NTSB record
The accident occurred during the first flight after the seaplane was issued an experimental airworthiness certificate. According to the pilot, the seaplane was a replica of a 100-year-old design and had very unconventional controls. The pilot reported that his initial flight test plan was to take off and then fly 1-2 feet above the water for a couple hundred yards before landing again. However, he stated that immediately after liftoff, the seaplane unexpectedly pitched up steeply. The pilot reduced the seaplane’s pitch attitude to avoid a stall, but the seaplane responded more rapidly than he expected so he increased its pitch attitude to avoid a collision with the water. The seaplane ultimately climbed to about 30 feet above the water before the pilot initiated a descent for a landing. The pilot reported that he “could not control the landing” and that the seaplane collided with the water in a nose-low and right-wing-low attitude. The pilot reported that there were no mechanical anomalies with the seaplane during the accident flight. In addition, he noted that his overall lack of flight experience in the seaplane contributed to the accident.
