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.

GAA19CA563
The pilot in the float-equipped airplane reported that he did not extend the flaps before he accelerated for takeoff from a lake. He added that, shortly after coming on step, he rolled the ailerons left and applied back pressure to the elevator to "become airborne." However, the airplane did not become airborne, and the floats subsequently impacted the shoreline. The airplane then bounced, skidded to a stop, impacted rising terrain, and came to rest upright. The airplane sustained substantial damage to the left elevator. The pilot reported that he had not maintained a sterile cockpit during takeoff and that he failed to complete the Before Takeoff checklist. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's improper takeoff configuration due to distraction, which resulted in the airplane’s failure to become airborne and its subsequent collision with rising terrain. Contributing to the accident was the pilot's failure to use the Before Takeoff checklist.

The pilot reported that he had not maintained a sterile cockpit during takeoff, and he failed to complete the Before Takeoff Checklist.
