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.

AFTER ENPLANING THREE PEOPLE, WHOSE TOTAL WEIGHT WAS ESTIMATED AT 300 POUNDS, THE PILOT TOOK OFF FROM A FAIR GROUND WITH A 9 TO 14 KNOT RIGHT QUARTERING TAIL WIND BLOWING. THE ENGINE AND MAIN ROTOR RPM DECREASED AS THE AIRCRAFT REACHED APPROXIMATELY 30 TO 40 FEET ABOVE THE GROUND. THE PILOT ATTEMPTED TO MAKE A LANDING IN A PARKING LOT THAT WAS DIRECTLY AHEAD OF HIS POSITION. THE HELICOPTER TURNED RIGHT WHEN THE SKIDS TOUCHED THE GROUND AND ROLLED FORWARD ON ITS NOSE.
NTSB Probable Cause
THE PILOT'S FAILURE TO MAINTAIN ROTOR RPM DURING THE TAKEOFF. CONTRIBUTING FACTORS WERE: THE PILOT'S LACK OF FAMILIARITY WITH THE AIRCRAFT AND UNFAVORABLE WINDS THAT EXISTED AT THE TIME OF TAKEOFF.
