The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19840718035489A](https://openairdocs.org/incident/19840718035489A), Jul 18, 1984: Scwzer G164A, Stanford, AR, Substantial damage. Lost control flying into his own prop wash while flying under wires. Turbulence raised a wing which hit the wires.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
