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 firefighting activity at the time of the accident. He reported that after scooping a load of water and applying takeoff power, the airplane encountered a large boat wake which caused it to become airborne. However, the pilot did not have sufficient flight control authority to counter act the engine torque. The left float contacted the water, and the airplane veered to the left. The left-wing spar was damaged during the impact sequence. The pilot reported that there were no mechanical failures or malfunctions before the accident that would have precluded normal airplane operation.
