## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - compensation for wind conditions - improper, pilot in command (cause)
  - improper use of procedure, pilot in command (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- Dragged wing,rotor,pod,float or tail/skid, landing - roll

## Analysis

THE PILOT LOST DIRECTIONAL CONTROL WHILE LANDING HIS TAIL WHEEL AIRPLANE IN A CROSSWIND. THE PILOT STATED THAT A GUST OF WIND LIFTED THE RIGHT WING AND HE WAS UNABLE TO PREVENT THE LEFT WING FROM CONTACTING THE RUNWAY. THE AIRPLANE EVENTUALLY CAME TO REST ON THE RUNWAY ON ITS NOSE AND LEFT WINGTIP.
