## Other investigations on N3857Y (1)

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.

- [NTSB ERA24LA095](https://openairdocs.org/ntsb/ERA24LA095), Jan 22, 2024: Cessna 210D (N3857Y), Paris, TN, substantial damage. Probable cause: The disruption of torque to the No 4 connecting rod journals, which resulted in a spun bearing and the subsequent total loss of engine power.
