- [Accident 19850805039209A](https://openairdocs.org/incident/19850805039209A), Aug 5, 1985: Cessna A188B, Trenton, AL, Destroyed. Pilot heard a bang while turning, engine lost power. Struck trees. Aircraft too badly burned to determine cause.

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.
