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.

TWO WORKERS WERE TRANSPORTED TO A MINE DRILLING SITE WHERE THE HELICOPTER WAS LANDED ON A MAN-MADE HELI-PAD. THE HELI-PAD WAS AN AREA ABOUT 50 FT LONG AND 12 FT WIDE THAT HAD BEEN CUT INTO THE SIDE OF A ROCKY HILL. AFTER OFF-LOADING THE WORKERS, THE PILOT TOOK OFF, THEN RETURNED A SHORT TIME LATER WITH A 300 GAL STORAGE TANK ON A LONG LINE. AFTER THE TANK WAS LOWERED INTO POSITION, THE HELICOPTER WAS LANDED AT THE END OF THE PAD UNTIL THE LINE WAS RELEASED. AS THE PILOT TOOK OFF AGAIN, HE LIFTED OFF AND WAS AT AN ALTITUDE OF ABOUT 3 TO 5 FT WHEN THE MAIN ROTOR BLADES CONTACTED THE ROCKY EMBANKMENT ON THE UPSLOPE SIDE OF THE HELI-PAD. REPORTEDLY. THE HELICOPTER THEN WENT INTO AN UNCONTROLLABLE SPIN AND TUMBLED ABOUT 300 FT DOWN THE HILL. ONE OF THE WORKERS WAS FATALLY INJURED BY A PIECE OF FLYING DEBRIS.
