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.

ERA10CA470
The pilot reported that he made a normal approach to the runway with a light headwind in his experimental light sport, weight-shift trike. During the landing flare, with the trike about 5 to 10 feet above the ground, it encountered a gust of wind. The pilot was unable to straighten the trike and it impacted the ground, resulting in substantial damage to the fuselage. The pilot reported no mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. The wind was reported as calm at an airport 8 miles to the north at the time of the accident.

Full Narrative
The pilot reported that he made a normal approach to the runway with a "light head wind" in his experimental light sport, weight-shift trike. During the landing flare, when the trike was about 5 to 10 feet off the ground, "an unexpected gust or ground turbulence threw [the trike] sharp right off the runway." The pilot was unable to straighten the trike, which then impacted the ground, resulting in substantial damage to the fuselage. The pilot reported no preexisting mechanical anomalies with the trike. The winds were reported as calm at an airport 8 miles to the north at the time of the accident.
