## Probable cause

THE LOSS OF DIRECTIONAL CONTROL AS A RESULT OF GUSTING WIND CONDITIONS.

## 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 - gusts (cause)
  - directional control - not maintained
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch (contributing factor)

## Analysis

DURING THE LANDING ROLL, THE AIRPLANE DECELERATED AND THE FLAPS WERE RETRACTED. AS THE PILOT TURNED OFF THE RUNWAY ONTO A TAXIWAY, A GUST OF WIND PICKED THE AIRPLANE UP AND TURNED IT 90 DEGREES TO THE LEFT. THE PILOT WAS UNABLE TO REGAIN CONTROL AS THE AIRPLANE SKIDDED ACROSS THE GROUND AND CAME TO REST IN A DRAINAGE DITCH. DUST DEVILS WERE REPORTED IN THE VICINITY OF THE AIRPORT.
