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.

GAA16CA276
The pilot reported that while landing on a wet grass runway, he touched down long, skidded about 200 feet, and was unable to slow the airplane. Subsequently, the airplane overran the runway and struck a fence about 20 feet beyond the end of the runway, which resulted in substantial damage to the firewall. The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's landing area overshoot and failure to maintain surface speed and braking capability, which resulted in a runway overrun and a collision with a fence.
Full Narrative
The pilot reported that while landing on a wet grass runway, he touched down long, skidded about 200 feet, and was unable to slow the airplane. Subsequently, the airplane overran the runway and struck a fence about 20 feet beyond the end of the runway, which resulted in substantial damage to the firewall. The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation. After multiple requests by the National Transportation Safety Board (NTSB) investigator-in-charge, the pilot failed to submit the NTSB Form 6120.1 Pilot/ Operator Aircraft Accident/ Incident Report.
