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
WPR23LA101
The flight instructor of an amphibious float-equipped airplane reported that, he was demonstrating to the student pilot a water landing and step taxi from the back seat. While in the step taxi and preparing to takeoff, the student alerted the flight instructor to a channel hazard marker directly in front of the airplane. The flight instructor was unable to respond before the left wing and left side float collided with the marker about a second later. The left wing and left side float separated from the fuselage resulting in substantial damage. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The flight instructor’s failure to see and avoid a channel marker during a step taxi in preparation for takeoff on the water.
