## Probable cause

THE PILOT'S FAILURE TO PROPERLY ALIGN THE AIRCRAFT WITH THE LANDING AREA.

## Sequence of events

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

- In flight encounter with weather, cruise - normal
  - weather condition - icing conditions
  - window,flight compartment window/windshield - ice
  - visual lookout - restricted
- In flight collision with terrain/water, landing - flare/touchdown
  - weather condition - snow
  - airport facilities,runway/landing area condition - snow covered
  - proper alignment - not attained, pilot in command (cause)
  - visual/aural detection, pilot in command (contributing factor)
  - terrain condition - snowbank
- Hard landing, landing - flare/touchdown

## Analysis

THE FLIGHT ENCOUNTERED ICING AT CRUISE, AND ICE REMAINED ON A PORTION OF THE WINDSHIELD DURING THE PILOT'S APPROACH. A LIGHT SNOW WAS FALLING, AND THE FIELD AND RUNWAY WERE SNOW-COVERED.  THE LEFT MAIN GEAR TOUCHED DOWN IN A SNOWBANK ON THE LEFT EDGE OF THE RUNWAY.
