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.

The airline transport certificated pilot reported that he was attempting to takeoff from a slough with a float-equipped airplane on a Title 14, CFR Part 135 on-demand air taxi flight. He stated that he aborted the first takeoff attempt due to shifting winds created by local thunderstorms, and elected to takeoff in the opposite direction. Shortly after liftoff, the pilot reported that the airplane encountered a severe downdraft, and descended onto the tundra, striking Alder and Willow bushes. The airplane sustained substantial damage to both wings and wing lift struts.
NTSB Probable Cause
The pilot's inadequate weather evaluation, which resulted in the airplane encountering a severe downdraft during takeoff initial climb, and an in-flight collision with terrain. Factors associated with the accident were a thunderstorm and a downdraft.
