## Sequence of events

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

- Loss of control - in flight, landing
  - directional control - not maintained, pilot in command (contributing factor)
  - compensation for wind conditions - poor, pilot in command (contributing factor)
  - go-around - initiated, pilot in command (contributing factor)
- In flight collision with terrain/water, landing - flare/touchdown
  - ground loop/swerve - inadvertent, pilot in command (cause)
- Fire, other

## Analysis

THE PILOT LOST CONTROL OF THE AIRCRAFT PRIOR TO TOUCHDOWN AFTER THE LEFT WING DIPPED APPROXIMATELY FOUR FEET. THE LEFT GEAR TOUCHED DOWN ALONGSIDE THE RUNWAY AND THE PILOT MADE AN ATTEMPT TO GO AROUND BUT CHANGED HIS MIND WHEN HE SAW A GROUP OF TREES AT THE END OF THE RUNWAY. THE PILOT WAS UNABLE TO REGAIN CONTROL OF THE AIRCRAFT BEFORE IT TOUCHED DOWN ON THE RUNWAY AND SKIDDED INTO A BRUSH AREA WHERE IT CAUGHT FIRE AND WAS DESTROYED.
