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 STUDENT PILOT WAS PRACTICING TAKEOFF AND LANDINGS IN THE LOCAL PRACTICE AREA. ON THE NINTH APPROACH, THE HELICOPTER DEVELOPED A HIGH RATE OF DESCENT AND A STEEP APPROACH ANGLE. THE STUDENT FLARED AND APPLIED POWER TO ARREST THE DESCENT. THE MAIN ROTOR RPM DECAYED AND THE HELICOPTER LANDED HARD AND BOUNCED INTO THE AIR. THE HELICOPTER ROLLED OVER ON THE SECOND TOUCHDOWN.
NTSB Probable Cause
THE STUDENT PILOT'S EXCESSIVE RATE OF DESCENT DURING A APPROACH FOR LANDING, IMPROPER REMEDIAL ACTION TO ARREST THE RATE OF DESCENT, AND A FAILURE TO MAINTAIN PROPER MAIN ROTOR RPM. THE STUDENT PILOT'S LACK OF TOTAL AERONAUTICAL EXPERIENCE WAS A FACTOR IN THIS ACCIDENT.
