| Confidence Rating: |  Accident investigation report completed and information captured |
According to the pilot, and corroborated by video capturing the accident, during a normal touchdown in a float-equipped airplane, the left float dug into the water and the airplane veered abruptly and nosed over.
A postaccident examination revealed a large hole in the bottom of the left float just forward of the step. Corrosion was present around the hole and no impact signatures were present on the bottom of the float. The circumstances of the accident are consistent with a loss of control during the water landing due to the failure of the left float due to corrosion.
Probable Cause: The failure of the left float bottom due to corrosion, which resulted in a loss of control during the water landing.
