## 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 DCA26LA102](https://openairdocs.org/ntsb/DCA26LA102), Jan 15, 2026: Boeing 737 (N583AS), Kodiak, AK, substantial damage. Probable cause: The reduced surface friction of the contaminated ramp which led to a loss of directional control during taxi.

## 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.
