NTSB narrative

The pilot reported that he was landing the float equipped airplane on a lake. The winds were light and the lake had about 3 inch ripples on the water. He reported that the touchdown appeared normal, but a few seconds later the right wing went up and the left wing dipped in the water. The left wing was bent upward and sustained substantial damage. A witness reported that he observed the airplane flying slow over the water in a left bank when the airplane “dropped into the lake” with the left wing hitting the water. The pilot reported there was no mechanical malfunction of the airplane.

Probable cause

The pilot's improper flare and touchdown during the water 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: 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.
