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 HOME BUILT, POWERED GLIDER WAS BEING FLOWN ON A LOCAL TEST FLIGHT. ACCORDING TO WITNESSES, THE ACFT WAS IN UNPOWERED FLT (GLIDING) WHEN IT ENTERED A DESCENT & CRASHED. AT ABOUT THE SAME TIME IT BEGAN DESCENDING, THEY OBSERVED SOMETHING SEPARATE FROM THE ACFT THAT APPEARED TO BE A WING. AN EXAM OF THE WRECKAGE REVEALED THE LEFT WING SKIN HAD SEPARATED FROM THE SPAR. THE LEFT SPAR WAS STILL ATTACHED TO THE FUSELAGE AND WAS BENT & TWISTED TOWARD THE TIP. THE ACFT HAD COME TO REST INVERTED & BOTH STABILIZERS OF THE V-TAIL HAD BROKEN. THE LEFT STABILIZER & LEFT WING SKIN WERE FOUND 185 & 300 FT, RESPECTIVELY, FROM THE MAIN WRECKAGE. AN INSPECTION OF THE LEFT WING REVEALED THAT THE SKIN HAD BEEN ATTACHED TO THE RIBS, BUT HAD NOT BEEN BONDED TO THE SPAR. ACCORDING TO THE ASSEMBLY INSTRUCTIONS, THE SKIN SHOULD HAVE BEEN BOND WITH EPOXY TO BOTH THE TOP & BOTTOM OF THE SPAR.
