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 AIR TAXI PILOT WAS ATTEMPTING TO TRANSPORT A HUNTING PARTY FROM A SMALL LAKE WHICH HE HAD NOT LANDED ON BEFORE. HE REPORTED THAT IT WAS HIS LAST FLIGHT OF A VERY BUSY FLYING DAY, AND THAT THE HUNTERS WERE ALREADY A DAY LATE IN BEING PICKED UP DUE TO THE WEATHER. HE SAID THAT WHILE HE WAS LANDING AND LOADING HIS PASSENGERS, THE WIND SHIFTED. HE WAS UNAWARE OF THE WIND SHIFT. THE WIND WAS BLOWING OVER A SMALL HILL BESIDE THE LAKE THAT CREATED A DOWNDRAFT. ACCORDING TO THE PILOT, WHEN THE AIRPLANE BECAME AIRBORNE, THE TAKEOFF WAS DELAYED DUE TO THE WINDSHIFT AND DOWNDRAFT, AND THE AIRPLANE WAS UNABLE TO GAIN SUFFICIENT ALTITUDE TO CLEAR THE FAR SHORE.
NTSB Probable Cause
IMPROPER PLANNING/DECISION BY THE PILOT. CONTRIBUTING FACTORS WERE: THE SURROUNDING TERRAIN, UNFAVORABLE WIND, DOWNDRAFT, THE PILOT'S LACK OF FAMILIARITY WITH THE GEOGRAPHICAL AREA, AND HIS SELF INDUCED PRESSURE.
