## Other investigations on N8943Z (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 ERA16LA213](https://openairdocs.org/ntsb/ERA16LA213), Jun 10, 2016: Cessna 310 (N8943Z), Apopka, FL, substantial damage. Probable cause: The intermittent failure of the left brake master cylinder, which resulted in asymmetric braking and the subsequent loss of directional control during the landing roll.
