  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - encountered, pilot in command
- On ground/water collision with object, landing

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.
