In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - in flight, landing - flare/touchdown
  - weather condition - crosswind (contributing factor)
  - flare - improper, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - not corrected, pilot in command (cause)
- On ground/water collision with object, landing - roll
