## 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 19850211030649I](https://openairdocs.org/incident/19850211030649I), Feb 11, 1985: Bag JETSTM3101, Macon, GA. Turned on engine anti ice but not ignitors in icing conditions. Double flameout and restarts.

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.
