## 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
  - directional control - not maintained, pilot in command (cause)
  - weather condition - crosswind (contributing factor)
  - terrain condition - icy (contributing factor)
  - notams - not identified, pilot in command (contributing factor)
  - preflight planning/preparation - poor, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - snowbank (contributing factor)

## Analysis

AT THE END OF A CROSS COUNTRY FLIGHT, DURING THE LANDING ROLL, THE AIRPLANE BEGAN TO SLIDE TO THE LEFT. THE PILOT WAS UNABLE TO REGAIN CONTROL DUE TO THE PATCHY SNOW AND ICE ON THE RUNWAY. THE AIRPLANE EXITED THE RUNWAY AND COLLIDED WITH A SNOW BANK. THERE WERE NO REPORTED MECHANICAL FAILURES OR MALFUNCTIONS AT THE TIME OF THE ACCIDENT. A NOTAM WAS IN EFFECT AT THE TIME OF THE ACCIDENT WHICH REPORTED THAT THE RUNWAY WAS CLOSED DUE TO THE ICY CONDITIONS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).
