Narrative

THE CFI SAID THE STUDENT PLT WAS AT THE CONTROLS & WAS MAKIN G A 
   TOUCH-&-GO LANDING ON RWY 12, WHICH WAS 2800 X 50 FT. THE WIND WAS FROM 
   THE SOUTH AT 10 KTS. THE TRAINEE LANDED LO NG, & BY THE TIME THE ACFT 
   WAS RECONFIGURED FOR TAKEOFF, ONLY ABOUT 800 FT OF RWY WAS REMAINING. 
   THE CFI THOUGHT THE TRAINEE WOULD STOP & TAXI BACK FOR TAKEOFF; 
   HOWEVER, THE TRAINEE ADVANCED THE THROTTLE FOR TAKEOFF. AT THAT TIME, 
   THE CFI TOOK THE CONTROLS, CLOSED THE THROTTLE & ATTEMPTED TO STOP. THE 
   ACFT SLID TO THE LEFT ON THE PACKED SNOW & ICE COVERED RWY, COLLIDED 
   WITH A SNOW BANK BESIDE THE RWY & NOSED OVER.
