## FAA reports on this event (1)

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

- [Accident 19870807043429A](https://openairdocs.org/incident/19870807043429A), Aug 7, 1987: Eagle DW1, Hamer, ID, Substantial damage. Aircraft departed end of runway onto tall weeds. Nosed over inverted. Departed downhill airstrip with a tailwind.

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.
