## NTSB investigations (291, newest 50)

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 CEN25LA306](https://openairdocs.org/ntsb/CEN25LA306), Aug 7, 2025: Air Tractor AT-301 (N23069), Davenport, ND, substantial damage, investigation ongoing
