Move quickly by aircraft, airport, operator, and time with indexes built for research, not wandering.
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.
Caputa, SD
The flight instructor reported that the student pilot pushed the throttle about 3/4 of the way in during the takeoff roll, and did not add full power until about 1/2 way down the 1,500 foot grass airstrip. The airplane had not attained flying airspeed by the time it reached the end of the runway. The airplane became airborne, but it settled and impacted the terrain, which resulted in substantial damage to the fuselage and right wingtip. The flight instructor reported that there were no preaccident malfunctions or failures with the airplane that would have precluded normal operation.
The student pilot's improper takeoff procedure and the flight instructor's failure to take control of the airplane and abort the takeoff.
