## 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 FTW04LA220](https://openairdocs.org/ntsb/FTW04LA220), Aug 24, 2004: Bell 212 (N181W), Umpire, AR, substantial damage. Probable cause: The pilot's encounter with settling with power resulting in a loss of control. A contributing factor was the high density altitude.

## FAA accident and incident reports (8)

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.
