## 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 WPR13FA380](https://openairdocs.org/ntsb/WPR13FA380), Aug 19, 2013: Nelson KR-2 (N9028Q), Cataldo, ID, substantial damage, 1 fatal. Probable cause: The pilot’s decision to intentionally enter a spin in the airplane, which had unknown spin characteristics due to the engine modification, from which he was unable to recover.

## 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.
