## 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 SEA07LA145](https://openairdocs.org/ntsb/SEA07LA145), Apr 1, 2007: Swearingen SA-226T (N46SA), McCall, ID, substantial damage. Probable cause: The nosewheel steering system's uncommanded turn during the landing roll, making it impossible for the pilot to maintain directional control. Factors include a snow bank running parallel to the side…

## 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.
