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 INSTRUCTOR PILOT (CFI) AND DUAL STUDENT WERE MAKING A RUN-ON LANDING WITH THE CFI RIDING THE CONTROLS AS THE DUAL STUDENT FLEW THE HELICOPTER. THE STUDENT WAS USING THE THROTTLE FOR YAW CONTROL. REPORTEDLY, HE ROLLED OFF TOO MUCH THROTTLE, AND THE CFI ANNOUNCED, 'I HAVE IT.' THE STUDENT WAS SLOW TO RELINQUISH AND THE CFI EXPERIENCED DIFFICULTY ROLLING THE THROTTLE UP WITH THE STUDENT STILL ON THE CONTROLS. THE CFI INITIATED A FLARE, BUT THE TAIL ROTOR STRUCK A VEHICLE BARRICADE. THE BARRICADE WAS LOCATED NEAR THE APPROACH END OF THE RUNWAY, AND IT PROJECTED ABOUT 12 INCHES ABOVE THE RUNWAY SURFACE.
NTSB Probable Cause
THE INSTRUCTOR PILOT'S (CFI'S) DELAY IN TAKING REMEDIAL ACTION AFTER HE AND/OR THE STUDENT FAILED TO ATTAIN THE PROPER TOUCHDOWN POINT FOR A RUN-ON LANDING. FACTORS RELATED TO THE ACCIDENT WERE: THE PROXIMITY OF THE BARRACADE AND THE STUDENT'S DELAY IN RELINQUISHING CONTROL OF THE HELICOPTER.
