NTSB narrative
The pilot of the amphibian airplane reported that, during takeoff from the lake, the airplane encountered a gust of wind, which lifted the left wing. While correcting the airplane encountered a second gust of wind, which raised the left wing, resulting in the right wingtip striking the water. Subsequently, the airplane nosed over and came to rest inverted within the water, which resulted in substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot’s failure to maintain lateral control of the airplane during takeoff in gusting wind.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
