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 LAX99LA240](https://openairdocs.org/ntsb/LAX99LA240), Jul 2, 1999: Cessna 421B (N5943M), Polacca, AZ, substantial damage. Probable cause: The pilot's inadequate preflight inspection, which failed to determine the fuel supply in each fuel tank, and his mismanagement of the fuel supply, which resulted in fuel starvation.
