## 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 19840909049579A](https://openairdocs.org/incident/19840909049579A), Sep 9, 1984: Gulstm AA1A, Pleasant Hill, MO, Destroyed. Aircraft struck a clump of sappling trees after takeoff which caused it to crash into trees beyond end of runway.

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.
