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

- [Accident 19890328004899A](https://openairdocs.org/incident/19890328004899A), Mar 28, 1989: Cessna 150L, Troy, MI, Destroyed, 1 fatal. Observed slow speed on downwind. Engine quit but started again as aircraft spun in. Believe pulled mixture in error

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.
