## Probable cause

THE PILOT'S FAILURE TO PERFORM A GO AROUND.  CONTRIBUTING TO THE ACCIDENT WAS THE ICY RUNWAY CONDITION AND THE FAILURE OF THE FSS PERSONNEL TO PROPERLY ISSUE AND DISSEMINATE A NOTAM CONCERNING THE ICY RUNWAY CONDITION.

## 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
  - airport facilities,runway/landing area condition - icy (contributing factor)
  - go-around - not performed, pilot in command (cause)
  - notams - not issued, atc personnel(fss) (contributing factor)
- Overrun, landing - roll
- On ground/water collision with object, landing - roll
  - object - tree(s)

## Analysis

THE AIRPLANE LANDED ON AN ICE AND WATER COVERED RUNWAY, THEN WAS UNABLE TO STOP BEFORE RUNNING OFF THE DEPARTURE END. ON THE PREVIOUS DAY, A PILOT HAD REPORTED, TO A NEARBY FAA FSS, THAT THE RUNWAY WAS COVERED WITH GLARE ICE AND WATER AND THAT THE BRAKING ACTION WAS NIL.  THIS INFORMATION WAS NOT PUT IN A NOTAM, AND THE ACCIDENT PILOT WAS NOT AWARE OF THE RUNWAY CONDITION PRIOR TO LANDING.
