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 Rotax 912 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 GAA18CA015](https://openairdocs.org/ntsb/GAA18CA015), Oct 18, 2017: Thomas G Parkhurst Kitfox IV (N37TP), Sidney, NY, substantial damage. Probable cause: The pilot's exceedance of the airplane’s critical angle of attack following a loss of ground reference during landing in glaring sun conditions, which resulted in an aerodynamic stall/spin.

## FAA accident and incident reports (1)

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
