## Probable cause

FAILURE OF THE STUDENT PILOT TO MAINTAIN DIRECTIONAL CONTROL, WHICH RESULTED IN AN INADVERTENT GROUND SWERVE.  THE SNOWBANK WAS A RELATED FACTOR.

## 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
  - airport facilities,runway/landing area condition - icy (contributing factor)
  - airport facilities,runway/landing area condition - snow covered (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)
- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - snowbank (contributing factor)

## Analysis

THE STUDENT PLT WAS PRACTICING TAKEOFFS & LANDINGS ON A RWY THAT WAS COVERED WITH ICE & SNOW. AFTER THE 4TH LANDING, HE APPLIED POWER TO TAKEOFF AGAIN. HE SAID THAT AFTER FULL POWER WAS APPLIED, THE ACFT BEGAN SLIDING SIDEWAYS. SUBSEQUENTLY, IT COLLIDED WITH A SNOWBANK & WAS DAMAGED.
