NTSB narrative
THE PILOT-IN-COMMAND STATED TWO OTHER AIRPLANES TOOK OFF FROM THE SLOUGH JUST BEFORE HIM. HE WAS THE LAST TO DEPART AND MADE HIS TAKEOFF RUN DOWNSTREAM ON THE SLOUGH. HE LIFTED OFF AT 50 TO 55 KNOTS AND THE AIRPLANE BEGAN TO SETTLE JUST AFTER LIFT OFF. THE PILOT STATED HE KNEW THE WATER WAS VERY SHALLOW AND TRIED TO MAINTAIN FLIGHT UNTIL REACHING DEEPER WATER. THE AIRPLANE SETTLED ONTO THE SLOUGH AND THE FLOATS STRUCK A MUD BAR AND THE AIRPLANE NOSED OVER. THE WIND WAS CALM. THE PILOT STATED THERE WERE NO MECHANICAL IRREGULARITIES DURING THE TAKEOFF. THIS WAS A BUSINESS FLIGHT CONDUCTED UNDER 14CFR91 BY A FISHING LODGE.
Probable cause
THE PILOT-IN-COMMAND'S FAILURE TO ATTAIN A PROPER CLIMB RATE.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1993-09-12.
