## Aircraft

- Registration: N944SP (not matched to a registry record)
- Reported make and model: CESSNA 411
- Category: Airplane
- Engines: reciprocating

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.
