## NTSB investigations (45)

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 ERA26LA052](https://openairdocs.org/ntsb/ERA26LA052), Nov 19, 2025: Toomey Long EZ (N82MT), Beaufort, SC, substantial damage, investigation ongoing
