Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

NTSB Number
GAA19CA551
The pilot reported that, while taking off from water to the east, the wind shifted from the east to the south. The airplane became airborne and then aerodynamically stalled, and the left wing impacted the water. The airplane came to rest inverted in the water. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's exceedance of the airplane's critical angle of attack while taking off from water in shifting wind conditions.
Full Narrative
The pilot of the float-equipped airplane reported that, during a water takeoff to the east, the wind shifted from the east to the south. The airplane became airborne, aerodynamically stalled, and the left wing impacted the water. The airplane came to rest inverted in the water. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported that the wind was from 115° at 30 knots, gusting to 30 knots.
