## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - weather condition - tailwind (contributing factor)
  - wrong runway - selected, pilot in command (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - aborted takeoff - performed, pilot in command
- On ground/water collision with object, takeoff - roll/run
  - object - tree(s) (contributing factor)

## Analysis

DIRECTIONAL CONTROL WAS LOST DURING THE TAKEOFF GROUND ROLL WITH A SLIGHT QUARTERING TAILWIND. POWER WAS REDUCED BUT THE ACFT TRAVELED OFF THE LEFT SIDE OF THE RWY WHERE IT COLLIDED WITH A TREE.
