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 LAKE RENEGADE 250 WAS MAKING A WATER TAKEOFF WHEN IT STARTED A SHARP LEFT TURN. THE AIRCRAFT STOPPED IN THE WATER AND THE PILOT EXITED WITHOUT INJURIES PRIOR TO THE AIRCRAFT TURNING OVER. EXAMINATION OF THE AIRCRAFT SHOWED THAT THE ENGINE PYLON HAD SEPARATED FROM THE FUSELAGE AND WAS ATTACHED ONLY BY THE RIGHT FLYING WIRE. THE OWNER HAD THE FAILED PARTS EXAMINED BY A INDEPENDENT LABORATORY AND THEY SAID THAT THERE WAS EVIDENCE OF A PRE-EXISTING FAILURE. WHEN THE PARTS WERE EXAMINED BY THE SAFETY BOARD'S METALLURGICAL LABORATORY, THEY WERE UNABLE TO SUPPORT THE RESULTS OF THE FIRST EXAMINATION AND CONCLUDED THE CAUSE OF THE FAILURE WAS OVERLOAD.
