## Probable cause

THE PILOT-IN-COMMAND'S FAILURE TO TAKE PROPER CORRECTIVE ACTION AFTER ENCOUNTERING A WIND GUST ON LANDING.

## Sequence of events

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

- On ground/water encounter with weather, landing - flare/touchdown
  - weather condition - gusts (contributing factor)
- Loss of control - on ground/water, landing - aborted
  - remedial action - inadequate, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - directional control - not maintained, pilot in command

## Analysis

WHILE LANDING, THE PILOT ENCOUNTERED A WIND GUST, ATTEMPTED TO TAKE OFF AGAIN, LOST DIRECTIONAL CONTROL AND RAN OFF THE RUNWAY INTO A NEIGHBORING FIELD.
