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.

DURING A SIMULATED SOFT FIELD, OBSTACLE CLEARANCE TAKEOFF AT ABOUT 60 FEET ABOVE THE GROUND, THE FLIGHT INSTRUCTOR GAVE HIS STUDENT A SIMULATED FORCED LANDING. AT ABOUT 20 FEET ABOVE THE RUNWAY DURING THE SIMULATED FORCED LANDING GLIDE, THE INSTRUCTOR NOTED A HIGH SINK RATE AND TOOK THE AIRCRAFT CONTROLS. THE AIRCRAFT LANDED HARD; BOUNCED BACK IN THE AIR; AND LANDED HARD AGAIN. DURING THE SECOND CONTACT, THE RIGHT WING CONTACTED THE RUNWAY CAUSING THE AIRCRAFT TO TURN RIGHT BY ABOUT 45 DEGREES. THE INSTRUCTOR, NOTING THAT HIS AIRCRAFT WAS TRAVELING TOWARD SOME AIRCRAFT PARKED TO HIS FRONT, MANEUVERED THE AIRCRAFT OFF THE RUNWAY TO AVOID A COLLISION. ABOUT 100 FEET AFTER DEPARTING THE RUNWAY, THE AIRCRAFT HIT A DITCH AND CAME TO A STOP.
