From the FAA registry file of October 24, 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 Pratt & Whitney R1340 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 FTW96LA135](https://openairdocs.org/ntsb/FTW96LA135), Feb 27, 1996: Rockwell S-2R (N431BL), Winchester, AR, substantial damage. Probable cause: Failure of the engine master rod.
