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 pilot reported that while on short final about 20 feet above the ground, he noticed the "attitude was a little flat." He reported that the airplane lost altitude "so fast, he didn't have time to react or even think to put the nose down or add power". The airplane impacted terrain, which resulted in substantial damage to the left wing. The pilot reported that his conclusion as to why the accident occurred was that the airplane "flat" stalled about 15 to 20 feet above the ground because he was "so focused on hitting the front of the runway" and didn't keep the airspeed "up." The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's failure to maintain pitch attitude, which resulted in the airplane exceeding its critical angle of attack and a subsequent aerodynamic stall/spin.
