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 HELICOPTER LOST POWER DURING TAKEOFF,TOUCHED DOWN ON THE LEFT SKID,BOUNCED AND ROLLED OVER. THE FLT HAD ORIGINATED AT 1315 AT A LOCAL FIELD AND PROCEEDED TO PICK UP A PASSENGER AT ANOTHER LOCATION. THE ACFT HAD JUST LANDED, PICKED UP THE PASSENGER AND WAS DEPARTING TO TAKE HIM TO A MINING CLAIMS SURVEY WHEN THE ACCIDENT OCCURRED. THE HELICOPTER WAS EXAMINED AND THE ENGINE WAS TORN DOWN BUT NO REASON FOR THE POWER LOSS WAS FOUND. IN THE FUEL GOVERNOR AND FUEL CONTROLLER SMALL BITS OF METAL, WOOD, CLOTH AND AN 'O' RING WERE FOUND. IN THE OPINION OF THE TECHNICIANS THIS WAS CONSISTENT WITH A SYSTEM OPERATING IN BYPASS & COULD NOT BY THEMSELVES HAVE CAUSED A SUDDEN PARTIAL LOSS OF POWER. SOME OTHER MINOR DISCREPANCIES WERE FOUND, NONE OF WHICH SHOULD HAVE AFFECTED NORMAL OPERATION OF THE ENGINE.
