Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot was performing a takeoff in an amphibious, float-equipped airplane. During the takeoff the pilot lost control, the airplane pitched forward, the floats dug into the water, and the airplane became airborne. The airplane rolled to the left, the left wing tip struck the water and subsequently nosed over. During the accident sequence the right wing, right aileron, and left wing strut were substantially damaged. When asked by the responding officer what he thought the cause of the accident was, he stated that it was a result of being a little high and slow on his approach, and the airplane hit the water hard, causing damage to the plane. The pilot later reported that there was a mechanical failure of the left float which was the result of a hard landing on asphalt five weeks before the accident. The pilot did not have any documentation of damage from the hard landing. He later stated that the takeoff did not feel right and that the entire flight he had to correct for the left wing dropping. The pilot stated to the responding officer that he did not examine all the components of the airplane before taking off. After reviewing video footage of the accident, it is unlikely that there were any preimpact mechanical failures or malfunctions that would have precluded normal operations.
