## 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 - gusts (contributing factor)
  - directional control - not possible, pilot in command (cause)
  - weather condition - thunderstorm (contributing factor)
- On ground/water collision with object, takeoff - roll/run
  - object - tree(s)

## Analysis

PLT NOTED APPROACHING THUNDERSTORM TO EAST AND ELECTED TO DEPART TO THE WEST DUE TO THE CURRENT WIND BEING CALM. DURING THE TAKEOFF ROLL A SUDDEN GUST FROM THE LEFT REAR CAUSED THE PILOT TO LOOSE DIRECTIONAL CONTROL AND THE AIRCRAFT WENT OFF THE LEFT SIDE OF THE RUNWAY COLLIDING WITH TREES.
