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.

GAA17CA034
The pilot of the high-performance airplane reported that, on his third simulated forced landing, while turning left base to final in a slip, he realized that the airplane was too low and not aligned with the runway. He applied full throttle to go around. The airplane responded suddenly by changing attitude but continued to descend and impacted terrain and the airport perimeter fence. The airplane sustained substantial damage to both wings and the fuselage. The pilot further reported that the slow airspeed coupled with the unexpected high torque from advancing the throttle during an uncoordinated left turn were factors in the accident. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s unstabilized approach and delayed application of full throttle for a go-around, which resulted in an uncontrolled descent.
