## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL.

## 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 encounter with terrain/water, takeoff - roll/run
  - terrain condition - snowbank
- Nose over, takeoff - roll/run

## Analysis

THE PILOT COMMENCED TAKEOFF ON A NARROW RUNWAY WITH A LEFT CROSSWIND COMPONENT.  THE AIRPLANE ANGLED LEFT.  THE PILOT CORRECTED ALIGNMENT WITH RIGHT RUDDER AND BRAKE, BUT WAS LEFT OF CENTERLINE.  WHEN HE RELEASED RIGHT BRAKE, THE AIRPLANE ANGLED LEFT INTO SNOW AT THE RUNWAY EDGE AND NOSED OVER.
