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.

During the landing roll on the dry grass strip, the pilot relaxed elevator pressure from the control stick before applying brakes and the airplane nosed over, coming to rest inverted. The airplane sustained substantial damage to the left wing, vertical stabilizer and the rudder. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. The pilot reported that he should not have released elevator back pressure before coming to a complete stop.
NTSB Probable Cause
The pilot’s failure to maintain elevator control during the landing, which resulted in a nose over.
