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 CRASHED WHILE MANEUVERING AT LOW ALTITUDE. THE PILOT HAD MODIFIED THE COWLING AND HAD ONLY COMPLETED THE FIRST PHASE OF HIS TRAINING IN THIS AIRCRAFT. THE SCHOOL WARNED THE STUDENT NOT TO TRY ADVANCED FLYING WITHOUT MORE INSTRUCTION. A WITNESS OBSERVED THE PILOT REFUELING THE HELICOPTER WITH A PARTIALLY FILLED, 5 GAL CAN OF AUTOMOBILE GASOLINE. HE STATED THAT HE THOUGHT THE FUEL TANK WAS NEARLY EMPTY WHEN THE PILOT BEGAN REFUELING. THEREFORE, THE WITNESS ESTIMATED THAT THE HELICOPTER HAD 5 GAL OR LESS ON BOARD WHEN IT TOOK OFF. HE ESTIMATED THAT THE ENGINE USED 8 TO 9 GAL PER HOUR. AFTER FLYING 15 TO 20 MIN, THE HELICOPTER ENTERED A DESCENT AND CRASHED. VIRTUALLY NO FUEL WAS FOUND IN THE HELICOPTER, AND THERE WAS NO EVIDENCE THAT FUEL HAD DRAINED OUT AT THE CRASH SITE.
