## 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
  - directional control - not maintained, pilot in command (cause)
  - aborted takeoff - delayed, pilot in command (cause)
  - nosewheel steering - not used, pilot in command (contributing factor)
- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - ground (contributing factor)
  - terrain condition - soft (contributing factor)
- On ground/water collision with object, takeoff - roll/run
  - object - runway light (contributing factor)

## Analysis

SHORTLY AFTER BEGINNING THE TAKEOFF ROLL, THE ACFT'S RIGHT MAIN GEAR RAN OFF THE RIGHT EDGE OF THE RUNWAY INTO SOFT WET GRASS. THE SOFT GROUND APPEARED TO CAUSE THE AIRPLANE TO CONTINUE RIGHT AND OFF THE RUNWAY WITH TAKEOFF POWER STILL APPLIED. THE ACFT CONTINUED ROLLING THRU THE GRASS, PARALLEL TO THE RUNWAY, COLLAPSING THE NOSE GEAR, RUNNING OVER A RWY LIGHT AND CROSSING ANOTHER RUNWAY. THE AIRCRAFT DECELERATED AND CAME TO A STOP IN THE GRASS. THE TAKEOFF RWY IS 50 FEET WIDE AND THE DISTANCE BETWEEN THE MAIN LANDING GEAR OF THE ACCIDENT ACFT IS 15 FEET.
