## FAA reports on this event (1)

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

- [Incident 19790807029559I](https://openairdocs.org/incident/19790807029559I), Aug 7, 1979: Beech 6580, Chantilly, VA. Smoke emitting from instrument panel. Regulator and alternators failed.

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.
