## Other investigations on N5300E (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 ERA19LA268](https://openairdocs.org/ntsb/ERA19LA268), Sep 11, 2019: Beech K35 (N5300E), St. Augustine, FL, substantial damage. Probable cause: An unintended brake application of the right main landing gear brake system during the landing rollout due to excessive play between the brake caliper anchor bolts and their bushings.
