## 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 19880713030719A](https://openairdocs.org/incident/19880713030719A), Jul 13, 1988: Piper PA22150, Kanosh, UT, Destroyed, 2 fatal. Struck a tree crashed and burned while flying in a canyon at a high density altitude.

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.
