## 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 DCA23LA421](https://openairdocs.org/ntsb/DCA23LA421), Aug 18, 2023: Boeing 777-222 (N209UA), Over the (Atlantic Ocean), no damage. Probable cause: An inadvertent encounter with clear air turbulence during cruise flight.
