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.

According to the pilot, he performed about 20 touch-and-go practice takeoffs and landings on the dry lake bed prior to the accident. He stated that the terrain was mostly flat, but in places it was uneven and rough. During the last landing, the airplane's wheels became bogged down in the soft terrain, and the propeller struck the ground. The pilot shut down the engine, inspected the propeller, and examined the planned takeoff path for suitability. Thereafter, he attempted to depart. As the airplane accelerated, the left main landing gear encountered an area of soft dirt. The airplane impacted a berm whereupon it nosed over, bending the wing structure and the vertical stabilizer. The pilot further reported that no mechanical malfunction had precipitated the accident.
