NTSB narrative
The pilot stated that he was performing a water landing in a cove with gusty wind conditions. The airplane touched down twice and, on the third touchdown, veered violently to the left. He believed that he either “chined and waterlooped” or that the left sponson contacted the water first. Both sponsons and the left wing tip were substantially damaged. Additionally, the left side of the airplane’s nose and left fuselage at the pilot entry station were wrinkled and bent.
Probable cause
The pilot did not maintain directional control during a water touchdown.

- 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. 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.
