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 automatic terminal information service reported that a crosswind existed with gusts up to 20 knots. The pilot said the air traffic controller confirmed the gusty wind conditions. The pilot stated that he approached and touched down using a left wing low wheel landing technique. Initially, the airplane was aligned with the runway’s centerline. After decreasing engine power and lowering the tailwheel, the pilot lost directional control. The right wing tip impacted the runway’s surface, and adjacent structural wing and aileron components were bent as the airplane veered off the runway and ground looped. The pilot reported that there were no mechanical anomalies that would have precluded normal operation.

Full Narrative
The pilot reported that the airport control tower provided wind information to him while he was in the traffic pattern for runway 31. The automatic terminal information service (ATIS) reported that the wind was from 270 degrees at 14 knots, with gusts to 20 knots. The pilot stated that he approached and touched down on the runway while using a left wing low wheel landing technique. Initially, the airplane was aligned with the runway’s centerline.
