## Probable cause

IMPROPER PLANNING/DECISION BY THE PILOT.  THE STRONG/GUSTY 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
  - planning/decision - improper, pilot in command (cause)
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command
  - ground loop/swerve - uncontrolled, pilot in command
- On ground/water encounter with terrain/water, landing
  - terrain condition - ditch (contributing factor)

## Analysis

THE PILOT INITIATED A LANDING ON RUNWAY 13 WITH A NEARBY STATION REPORTING WINDS FROM 230 DEG AT 17 GUSTING 25 KTS. AFTER TOUCHDOWN, THE AIRCRAFT VEERED TO THE LEFT & WENT OFF THE RUNWAY.  THE PILOT INITIATED A GO-AROUND.  HE SAID THE AIRCRAFT LIFTED OFF, BUT TOUCHED DOWN AGAIN IN A 'SOFT GRASS' AREA, WHICH CAUSED A SPEED LOSS.  HE THEN ABORTED THE GO-AROUND, BUT WAS UNABLE TO STOP THE AIRCRAFT BEFORE IT WENT THRU A DITCH & WAS DAMAGED.
