## Probable cause

DIRECTONAL CONTROL WAS NOT MAINTAINED BY THE PILOT IN COMMAND.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - directional control - not maintained, pilot in command (cause)
- On ground/water collision with object, takeoff - roll/run
  - terrain condition - snowbank (contributing factor)

## Analysis

WHILE ATTEMPTING TO TAKEOFF FROM A FRESHLY, SNOW PLOWED RUNWAY, THE PRIVATE PILOT LOST DIRECTIONAL CONTROL, VEERED OFF THE RUNWAY AND COLLIDED WITH A SNOWBANK.
