NTSB narrative

The pilot stated that he was performing touch-and-go practice takeoffs and landings in his seaplane in glassy water conditions. The first two landings were harder than normal and the airplane bounced. On the third landing, the airplane landed hard and nosed over. The pilot recalled that his airspeed during the approach was 60 knots and was descending at 150 feet-per-minute. He additionally stated that, after crossing the shoreline, he glanced down at the vertical speed indicator where his eyes remained focused during the impact with the water. He said that there were no preimpact mechanical problems with the airplane.

Probable cause

The pilot's inadequate flare, which resulted in a nose-low impact with glassy water and a subsequent nose-over. Contributing to the accident was the pilot's diverted attention while landing.

  • 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, coordinates. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2010-07-18.
