NTSB narrative
During an air taxi flight, the pilot executed a glassy-water landing on a remote lake with an excessive descent rate which resulted in a hard landing and go-around. The pilot later successfully landed the airplane without further incident. The hard landing resulted in the front seat passenger sustaining a broken rib. All three persons aboard were seated and wearing lap belts without shoulder harasses. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. The front-seat passenger stated the sun’s position in the sky – combined with the glassy water surface conditions - produced significant sun glare, especially on the pilot’s side of the airplane.
Probable cause
The pilot’s failure to maintain an appropriate descent rate for a glassy water landing, which resulted in a hard landing.

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, coordinates, 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.
