## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - proper alignment - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - crop (contributing factor)

ON TOUCHDOWN THE AIRCRAFT WAS NOT PROPERLY ALIGNED WITH THE RWY. WHILE ROLLING OUT THE LEFT WING CAUGHT THE FULL GROWN CORN ON THE LEFT EDGE OF THE RWY AND PULLED THE AIRCRAFT INTO THE CORN.
