## Analysis

THE ACFT COLLIDED WITH A FOUR FT SNOWBANK AT THE RWY THRESHOLD DURING LANDING. THIS WAS A DUAL INSTRUCTIONAL FLT WITH THE STUDENT IN THE RIGHT SEAT. THE CFI HAD MADE NO LANDINGS IN THIS MAKE AND MODEL OF ACFT IN THE PREVIOUS 90 DAYS. THE PILOT STATED THAT DUE TO THE LIGHTING AND SNOW IN THE BACKGROUND THE DEFINITION OF THE SNOWBANK WAS HARD TO DISTINGUISH DURING THE APPROACH.
