From the FAA registry file of October 22, 2026. ADs below are matched by the registry's airframe and engine model codes. They may apply; each AD's applicability can narrow it by serial number, part number or installed equipment. This is not a compliance determination. The registry lists only the engine series, so ADs for every CFM International CFM56 model are included.

## 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 DCA25LA190](https://openairdocs.org/ntsb/DCA25LA190), Apr 20, 2025: Boeing 737-7H4 (N461WN), Tahlequah, OK, no damage. Probable cause: The airplane’s encounter with moderate turbulence during descent.
- [NTSB LAX04IA302](https://openairdocs.org/ntsb/LAX04IA302), Aug 19, 2004: Boeing 737-7H4 (N461WN), Los Angeles, CA, incident, no damage. Probable cause: a loss of separation between Southwest flight 440 and Asiana flight 204 due to the LC2 relief controller's failure to appropriately monitor the operation and recognize a developing traffic conflict.…
