## Probable cause

IMPROPER PLANNING/DECISION BY THE PILOT.  THE WET CONDITION OF THE GRASS RUNWAY WAS A RELATED FACTOR.

## Sequence of events

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

- Overrun, landing - roll
  - planning/decision - improper, pilot in command (cause)
  - airport facilities,runway/landing area condition - grass
  - airport facilities,runway/landing area condition - wet (contributing factor)
- On ground/water collision with object, landing
  - object - fence (contributing factor)
- On ground/water encounter with terrain/water, landing
  - terrain condition - ditch (contributing factor)

## Analysis

THE PILOT STATED THAT HIS APPROACH TO LANDING AND TOUCHDOWN WAS NORMAL.  HE REPORTED THAT THE AIRCRAFT DID NOT SLOW PROPERLY AND STARTED TO SLIDE DURING THE LANDING ROLL. ALSO, HE STATED THAT THE TURF RUNWAY WAS 'FROZEN AND HARD,  BUT THE GRASS WAS WET DUE TO THE WARM WEATHER.' HE ESTIMATED THE TEMPERATURE WAS 40 DEGREES WITH WINDS OUT OF THE NORTHWEST AT ZERO TO FIVE KNOTS. SUBSEQUENTLY, THE AIRCRAFT CONTINUED OFF THE DEPARTURE END OF THE RUNWAY, WENT THROUGH A FENCE AND COLLIDED WITH A DITCH.
