## 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 DCA23LA382](https://openairdocs.org/ntsb/DCA23LA382), Jul 28, 2023: Boeing 737-924ER (N77431), Myrtle Beach (Atlantic Ocean), no damage. Probable cause: An encounter with convectively induced turbulence (CIT) while in cruise flight.

## FAA accident and incident reports

None matched to N77431.

## Service difficulty reports (44)

As reported by operators and repair stations. Matched to this aircraft by N-number and event date, checked against the reported serial number, make and model.
