## 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 19861108054219A](https://openairdocs.org/incident/19861108054219A), Nov 8, 1986: Child S1TPITTS, Miami, FL, Substantial damage. Aircraft settled into terrain after recovery from an aerobatic spin maneuver. Pilot had air show waiver.

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.
