## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRCRAFT.  THE GUSTY/QUARTERING CROSSWIND WAS A RELATED FACTOR.

## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- On ground/water collision with object, landing - roll
  - object - sign

## Analysis

DURING THE LANDING ROLL, A SUDDEN GUST OF WIND STRUCK THE AIRCRAFT. THE PILOT LOST CONTROL OF THE AIRCRAFT AND IT STRUCK A RUNWAY DISTANCE MARKER.
