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 rollout on the instructional flight, the airplane encountered a right crosswind and started veering to the right. According to the certified flight instructor (CFI), he took the controls just as a wind gust struck the right side of the airplane, which resulted in the left wingtip striking the runway. The CFI stated full opposite control was insufficient to prevent the right wing from rising and the left wing tip from scraping the runway. Postaccident examination of the airplane revealed substantial damage to the left aileron.
NTSB Probable Cause
