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 PILOT INDICATED THAT PRIOR TO DEPARTURE HE HAD RECEIVED A FULL WEATHER BRIEFING AND NO SIGNIFICANT WEATHER WAS FORECAST FOR HIS ROUTE OF FLIGHT. THE INITIAL PORTION OF THE FLIGHT WAS UNEVENTFUL. HOWEVER, WHEN THE PILOT ENTERED A MOUNTAIN PASS AREA AT HIS CRUISE ALTITUDE OF 500 FEET ABOVE GROUND LEVEL, THE WINDS BECAME VERY STRONG AND HE EXPERIENCED SEVERE TURBULENCE. THE PILOT FURTHER REPORTED THAT HE ATTEMPTED TO TURN INTO THE WIND FOR THE PURPOSE OF MAKING AN EMERGENCY LANDING.

NTSB Probable Cause
THE PILOT'S FAILURE TO MAINTAIN A PROPER CRUISE ALTITUDE UPON ENTERING A MOUNTAIN PASS AREA, AND HIS FAILURE TO MAINTAIN CONTROL OF THE HELICOPTER. FACTORS WHICH CONTRIBUTED TO THE PILOT'S LOSS OF CONTROL WERE RELATED TO HIS ENCOUNTERING TURBULENCE AND DOWNDRAFTS.
