NTSB narrative
In a phone conversation, the pilot reported that he looked over the area before he landed and did not see anything in the water and did not see anything off the right side. He reported that the right wing caught the water. He reported, 'I think it was the glassy water...and I thought I was higher than I was.' He reported, '...the wing hit the water and the airplane ground looped on me.' The pilot reported that he had 19 hours in make and model aircraft.
Probable cause
the pilot misjudged the flare and inadvertently dragged the right sponson in the water. A factor was the pilot's lack of experience in the make and model aircraft.

- 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.
