## Probable cause

THE FAILURE OF THE PILOT TO MAINTAIN DIRECTIONAL CONTROL DURING THE TAKEOFF ATTEMPT. A FACTOR IN THE ACCIDENT WAS THE ICY, SNOW COVERED CONDITION OF THE TAKEOFF AREA.

## 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
  - terrain condition - icy (contributing factor)
  - terrain condition - snow covered (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - not corrected, pilot in command (cause)
- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - snowbank
- Nose over, takeoff - roll/run

## Analysis

THE PILOT LANDED ON THE HIGHWAY THE NIGHT BEFORE DUE TO BAD WEATHER CONDITIONS ENCOUNTERED EN ROUTE. HE ATTEMPTED TO TAKEOFF ON THE SNOW COVERED HIGHWAY THE NEXT MORNING. THE PILOT COULD NOT MAINTAIN DIRECTIONAL CONTROL DURING THE GROUND RUN AND THE AIRCRAFT COLLIDED WITH A SNOW BANK ON THE LEFT SIDE OF THE ROAD, THEN NOSED OVER.
