Event Overview
An amphibious airplane was conducting a takeoff from a lake when the pilot decided to reject the takeoff. The rejection was prompted by the presence of power lines and a bridge in the direction of takeoff; the pilot was uncertain whether the airplane would be able to clear them.
Rejected Takeoff and Subsequent Maneuvers
During the rejected takeoff, the pilot reduced engine power. Despite the power reduction, the airplane became airborne. The pilot then initiated a slight right turn toward more open water.
Touchdown and Water Loop
After touching down on the water, the airplane "water looped," a term describing a loss of directional control on water resulting in a sharp turn. The aft portion of the fuselage was substantially damaged during the accident sequence.
Mechanical Status
The pilot reported that there were no preaccident mechanical malfunctions or failures of the airplane that would have precluded normal operation.
