## 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 19860201018139A](https://openairdocs.org/incident/19860201018139A), Feb 1, 1986: Amtrpk TEENIE2, Owasso, OK, Destroyed. Impacted ground in an uncontrolled descent while turning into setting sun. Was doing lazy eights at a low altitude.

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.
