## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - lift-off - premature, pilot in command (cause)
  - weather condition - high density altitude
- On ground/water collision with object, takeoff - aborted
  - terrain condition - rough/uneven
  - object - fence

THE PLANE SETTLED BACK ON THE STRIP WITH THE NOSE WHEEL TURNED TO THE RIGHT, THE PILOT SAID THE PLANE TURNED RIGHT ABRUPTLY, DEPARTED THE RUNWAY, STRUCK A FENCE AND CAME TO REST NOSE DOWN, WITH WING AND EMPENNAGE DAMAGE.
