NTSB narrative

The pilot of the float-equipped airplane reported that while accelerating on the water for takeoff, he impacted a green channel buoy and nosed over, which resulted in substantial damage to the left wing, left lift strut and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or anomalies with the airplane that would have precluded normal operation, and that the accident may have been prevented if he had taxied clear of the obstructions before initiating his takeoff.

Probable cause

The pilot’s impact with a buoy on takeoff which resulted in a nose-over.

  • 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.
