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 (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 DCA15CA050](https://openairdocs.org/ntsb/DCA15CA050), Dec 11, 2014: Boeing 737 7H4 (N481WN), San Jose, CA, no damage. Probable cause: an inadvertent encounter with convective turbulence during descent.

## FAA accident and incident reports

None matched to N481WN.

## Service difficulty reports (317, newest 50)
