## Probable cause

CONTINUED FLIGHT BY THE PILOT INTO KNOWN ICING CONDITIONS, AND HIS IMPROPER PLANNING/DECISION, WHICH RESULTED IN AN OVERRUN OF THE RUNWAY AFTER HE DIVERTED TO AN ALTERNATE AIRPORT.  THE ADVERSE WEATHER CONDITION, ICY RUNWAY, AND CHAIN LINK FENCE NEAR THE END OF THE RUNWAY WERE RELATED FACTORS.

## Sequence of events

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

- In flight encounter with weather, cruise
  - weather condition - icing conditions (contributing factor)
  - flight into known adverse weather - continued, pilot in command (cause)
  - wing - ice (contributing factor)
  - performed, pilot in command
- Overrun, landing - roll
  - airport facilities,runway/landing area condition - icy (contributing factor)
  - in-flight planning/decision - improper, pilot in command (cause)
- On ground/water collision with object, landing
  - object - fence (contributing factor)

## Analysis

THE PILOT SAID THAT DURING A CROSS-COUNTRY FLIGHT, THE ACFT ENCOUNTERED AIRFRAME ICING.  HE DIVERTED TO CARTHAGE, MO. HE SAID THAT AFTER TOUCHDOWN ON AN ICE COVERED RUNWAY, HE WAS UNABLE TO STOP THE AIRCRAFT AND IT SLID OFF THE END OF THE RUNWAY & INTO A CHAIN LINK FENCE.  BEFORE THE FLIGHT, THE PILOT HAD BEEN ADVISED OF ICING CONDITIONS IN THE AREA.
