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 PLT STATED THAT DURING HIS FIRST PASS WHILE OVER TREES, FOR A PHOTOGRAPHIC RUN, THE HELICOPTER EXPERIENCED A SLIGHT YAWING TENDENCY. DURING THE SECOND PASS AT THE SAME AIRSPEED BUT AT A LOWER ALTITUDE (BETWEEN 25 AND 50 FT ABOVE THE TREES) THE HELICOPTER ENTERED AN UNCOMMANDED RT YAW. HE LOWERED THE COLLECTIVE CONTROL AND PUSHED THE CYCLIC BUT DID NOT ADJUST THE THROTTLE. THE SPINNING DESCENT CONTINUED UNTIL IMPACT WITH THE TREES THEN THE GROUND. EXAM OF THE DAMAGED TAIL ROTOR BLADES BY AN FAA AIRWORTHINESS INSPECTOR INDICATE EVIDENCE OF ROTATION AT IMPACT. THE PLT'S BOSS WAS THE PHOTOGRAPHER.
NTSB Probable Cause
INCORRECT AIRSPEED, INSUFFICIENT AIRSPEED, AND FAILURE OF THE PILOT IN COMMAND TO PERFORM THE CORRECT EMERGENCY PROCEDURE FOLLOWING THE IN FLIGHT LOSS OF CONTROL. CONTRIBUTING TO THE ACCIDENT WAS SELF INDUCED PRESSURE BY THE PILOT IN COMMAND.
