## 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 19840413013689A](https://openairdocs.org/incident/19840413013689A), Apr 13, 1984: Ayres S2RRESTD, Monette, AR, Substantial damage. Engine quit on climbout. Dumped load and crash landed. Supercharger vanes and shaft bearings were eroded away.

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.
