## 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 19870609020109A](https://openairdocs.org/incident/19870609020109A), Jun 9, 1987: Dhav DHC2*, Sparrevohn, AK, Substantial damage. The float equipped plane struck a tree during a river landing. Wind shift during flare pushed aircraft into bank.

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.
