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.

INVESTIGATION REVEALS THE HELICOPTER TOUCHED DOWN ON THE HEEL OF ITS SKIDS, LEFT SKID FIRST, AND AT A SLIGHTLY LOW ROTOR RPM. THE TAIL BOOM THEN MOVED UPWARD WHILE THE MAIN ROTOR BLADES FLEXED DOWNWARD. THE MAIN ROTOR BLADES CONTACTED AND SEVERED THE TAIL BOOM, ALLOWING THE TAIL ROTOR ASSEMBLY TO FALL TO THE GROUND. FRESH MARKS WERE NOTED ON THE MAIN ROTOR HUB ASSEMBLY WHERE IT HAD BANGED AGAINST THE MAIN ROTOR DROOP STOPS.
