## 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
  - weather condition - unfavorable wind (contributing factor)
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - compensation for wind conditions - improper, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
- On ground/water collision with object, landing - roll
  - object - fence (contributing factor)

## Analysis

THE AIRCRAFT COLLIDED WITH A FENCE DURING LANDING ON A NARROW STRIP IN A VARIABLE CROSSWIND. THE PILOT HAD TAKEN OFF FROM THE SAME AIRSTRIP EARLIER WITHOUT DIFFICULTY. HE SAID A STRONG GUST OF WIND STRUCK HIS AIRCRAFT AS IT WAS TOUCHING DOWN. THIS DISPLACED THE AIRCRAFT TO THE RIGHT WHERE THE RIGHT WINGTIP STRUCK THE FENCE AND GROUNDLOOPED THE AIRCRAFT. THE PILOT STATED THAT TREES NEAR THE LEFT SIDE OF THE RUNWAY RESULTED IN A VERY UNSTABLE WIND CONDITION AT TOUCHDOWN.
