## 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 19850421044639A](https://openairdocs.org/incident/19850421044639A), Apr 21, 1985: Helio H295, John Day, OR, Substantial damage. Aircraft was mushed into trees due to airframe icing. Above gross weight. Pilot not fixed wing or IFR rated.

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.
