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 (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 GAA19CA185](https://openairdocs.org/ntsb/GAA19CA185), Mar 28, 2019: Rockwell S 2R (N4250X), Hermiston, OR, substantial damage. Probable cause: The pilot's distraction due to a spray handle opening and his improper pitch trim setting during final approach, which resulted in an excessive pitchdown when he took his hand off the controls to…
