Accident Details
A float-equipped airplane sustained substantial damage to both wings during a takeoff from an ocean bay. According to the pilot, while the airplane was on step and she turned into the wind, the left wing and float raised. The right wing subsequently impacted the water, causing the airplane to pivot approximately 90 degrees clockwise before coming to rest partially submerged on its left side.
Pilot Report
The pilot reported that there were no preaccident mechanical failures or malfunctions that would have precluded normal operation. She added that it was suggested the airplane may have encountered a whale, but she did not feel any impact or bump during the takeoff.
Video Evidence
The National Transportation Safety Board (NTSB) reviewed a video of the takeoff taken from the shore. The footage shows the airplane making a sweeping left turn on the step, moving away from the camera. Wind indications in the video show the wind coming from the airplane's left. The left turn appears to tighten as the airplane comes into the wind, at which point the left wing and float lift, and the right wing strikes the water, ending the takeoff run.
Weather Information
The automated weather observation system located about 4 nautical miles from the accident site reported that, around the time of the accident, the wind was from 330 degrees at 8 knots. The pilot was departing to the northwest. However, the pilot reported that the wind at the accident site was light and variable at 0 to 5 knots.
