This tool presents statistical analysis of NTSB accident data for experimental amateur-built aircraft. The data is provided for informational and educational purposes only.
This data should not be the sole basis for any aircraft purchase, build, or flight decision. Aviation safety depends on many factors not captured here, including pilot training, recency, weather decision-making, maintenance practices, and individual judgment.
Key limitations of this data:
The analysis follows Ron Wanttaja's "initiator" methodology, which reframes NTSB probable cause data to identify the first event in the accident chain. This is an analytical framework, not an official NTSB classification.
If you are considering building or purchasing an experimental aircraft, consult experienced builders, flight instructors with type-specific experience, and your local EAA chapter. No website can substitute for hands-on guidance.
We believe safety data should be free and accessible to everyone in the experimental aircraft community. This tool is free to use and always will be. If you find it valuable, consider supporting the project.
