## NTSB investigations (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 DCA23LA086](https://openairdocs.org/ntsb/DCA23LA086), Nov 30, 2022: Boeing 737 (N946WN), Denver, CO, no damage. Probable cause: The flight’s encounter with mechanical turbulence.

## FAA accident and incident reports
