## 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 ANC97FA037](https://openairdocs.org/ntsb/ANC97FA037), Mar 25, 1997: Short Brothers SC7 (N451SA), Nunapitchuk, AK, destroyed, 2 fatal. Probable cause: inadequate visual look-out by the pilots of both airplanes, which resulted in their failure to see-and-avoid each other's airplanes.

## FAA accident and incident reports (2)

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.
