The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19870614020309A](https://openairdocs.org/incident/19870614020309A), Jun 14, 1987: Grtlks 2T1A, Drapper Cove, TX, Substantial damage. Struck a powerline while flying at a low altitude over a lake. Aircraft crashed into the water.

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.
