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 PILOT SAID THAT DURING LANDING ROLL ON A FUEL STOP, THE AIRPLANE SWERVED TO THE LEFT. HE ATTEMPTED TO CORRECT WITH RIGHT BRAKE, TO NO AVAIL. THE PLANE GROUND LOOPED OFF THE LEFT SIDE OF THE RWY AND ENTERED SOFT TERRAIN. THE PLANE NOSED OVER AND CAME TO REST INVERTED. A POST-ACCIDENT INVESTIGATION BY AN FAA INSPECTOR REVEALED THAT THE RIGHT BRAKE PADS WERE WORN AND REQUIRED MORE FLUID FROM THE BRAKE RESERVOIR. THE FLUID LEVEL IN THE RESERVOIR WAS LOW. NO LEAKS OR OTHER PROBLEMS WERE FOUND ON THE BRAKE SYSTEM. THIS AIRCRAFT WAS AN EXPERIMENTAL DESIGN WITH LANDING GEAR ON THE TOP SIDE OF THE WINGS, MAKING IT CAPABLE OF INVERTED LANDINGS. THE SAME FLUID RESERVOIR SERVED BOTH SETS OF BRAKES.
NTSB Probable Cause
THE PILOT-IN-COMMAND'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL AFTER A PARTIAL FAILURE OF THE NORMAL BRAKE SYSTEM.
