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 during the landing approach in the tailwheel-equipped airplane, he encountered rough air, and the airplane landed hard and bounced. The airplane subsequently came to rest inverted, substantially damaging the wings and fuselage. At the time of the accident, the airplane was landing with a right quartering tailwind of 10 knots, gusting to 14 knots. 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 airplane control during the landing flare in tailwind conditions, which resulted in a hard landing.
