## 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 19890614015609A](https://openairdocs.org/incident/19890614015609A), Jun 14, 1989: Gulstm AA5, Columbus, OH, Destroyed. Lost control, crashed on the ramp after encountering wake turbulence from a prior landing 737. Too low, too close.

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.
