## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - airspeed - improper, pilot in command (contributing factor)
  - ground loop/swerve - inadvertent, pilot in command (cause)
- On ground/water collision with object, landing - flare/touchdown
  - object - fence

## Analysis

THE PILOT REPORTED LANDING AT ABOVE NORMAL SPEED, WHEN HE LOST CONTROL OF THE AIRCRAFT AT TOUCHDOWN. THE AIRCRAFT THEN VEERED OFF THE RUNWAY ONTO WET GRASS. DO TO THE SLIPPERY CONDITIONS, THE AIRCRAFT BEGAN SLIDING UNTIL IT COLLIDED WITH A FENCE 100 FEET FROM THE END OF THE RUNWAY. A FENCE POST CAUGHT THE RIGHT WING, CAUSING THE RIGHT WING TO DISLODGE FROM THE FUSELAGE.
