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 PLT COULD NOT LOWER THE LANDING GEAR THROUGH USE OF THE NORMAL GEAR EXTENSION SYSTEM. HE WAS ABLE TO PARTIALLY LOWER IT THROUGH THE USE OF THE EMERGENCY EXTENSION SYSTEM. NEXT HE MADE AN EMERGENCY LANDING AT THE DEPARTURE AIRPORT DURING THE HOURS OF DARKNESS. THE NOSE GEAR REMAINED DOWN BUT UNLOCKED WHILE THE MAIN GEARS FOLDED BACK INTO THEIR WHEEL WELLS. THE AIRCRAFT VEERED OFF THE RUNWAY AND THE RIGHT SIDE OF ITS HORIZONTAL STABILATOR STRUCK A SHORT WOOD POST AND BROUGHT THE AIRCRAFT TO A STOP. INVESTIGATION REVEALED THAT THE HYDRAULIC FLUID SUPPLY HAD BEEN DEPLEATED THROUGH A FATIGUE CRACKED ALUMINUM PRESSURE LINE, THUS CAUSING THE HYDRAULICALLY OPERATED LANDING GEAR SYSTEM TO BE INOPERATIVE BY USE OF ITS NORMAL OR EMERGENCY EXTENSION SYSTEMS.
