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
WPR25LA198
The pilot of the amphibious airplane reported that during takeoff from a lake in windy conditions, the airplane encountered windshear, stalled, and landed hard on the water surface, which resulted in the right float to separate. A video of the accident sequence showed the airplane veer right on the water during takeoff from the lake and became airborne. Once airborne, the airplane rolled right and then left before it landed hard on the water. A short time later, the airplane became submerged under the water surface. The right wing was substantially damaged. There were no preaccident mechanical malfunctions or failures that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to maintain control of the airplane and exceedance of the critical angle of attack during takeoff in windy conditions which resulted in a subsequent hard landing.
