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.

NTSB Number
CEN21LA344
The pilot reported that during landing on a grass runway, the airplane first bounced about 5 ft high, then bounced a few more times as it neared the end of the runway. The pilot added that he did not have enough remaining runway to complete a go-around, so he applied the brakes, but they did not work. The airplane continued off the end of the runway and impacted a small ditch and sustained substantial damage to the fuselage and engine mount. A postaccident examination of the brake system revealed no mechanical malfunctions or anomalies that would have precluded normal operation.
NTSB Probable Cause
The pilot’s improper landing flare which resulted in a bounced landing, a loss of control, and runway excursion.
