## 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 LAX94LA163](https://openairdocs.org/ntsb/LAX94LA163), Mar 13, 1994: Rockwell 681 (N78CH), Phoenix, AZ, substantial damage. Probable cause: the failure of the hydraulic and nitrogen system pressure lines, due to an inadequate maintenance inspection program, which failed to detect the corrosion condition of the lines.

## FAA accident and incident reports (3)

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.
