## NTSB investigations (2)

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 ERA26LA320](https://openairdocs.org/ntsb/ERA26LA320), Aug 27, 2026: Hawker Beechcraft 400A (N199TT), Newark, NJ, substantial damage, investigation ongoing
