## 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 19860614024119A](https://openairdocs.org/incident/19860614024119A), Jun 14, 1986: Amtrso ACRODUSTER2, St Louis, MO, Destroyed, 1 fatal. Immediately after liftoff a vertical climb was initiated. Aircraft stalled, did not recover from subsequent dive.

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.
