Narrative

THE INSTRUCTOR AND PILOT RATED STUDENT WERE PRACTICING PATTERN WORK.  
   THE INSTRUCTOR ASKED THE STUDENT TO SWITCH THE FUEL SELECTOR FROM THE

   NOT LOOK AT IT.  HE INADVERTENTLY SELECTED THE OFF POSITION.  THE 
   ENGINE QUIT, A ND COULD NOT BE RESTARTED.  THE INSTRUCTOR LANDED THE 
   AIRPLANE ABOUT 50 YARDS SHORT OF THE RUNWAY.  THE MAIN LANDING GEAR 
   WHEELS DUG INTO THE SNOW DURING LANDING ROLL, AND THE AIRPLANE 
   NOSED-OVER.

Accident occurred FEB-21-94 at GRAND FORKS, ND
Aircraft: PIPER PA-18-150, registration: N66ND
Injuries: 2 Uninjured.

The instructor and pilot rated student were practicing pattern work. The instructor asked the student to switch the fuel selector from the right tank to the left tank. The student moved the selector but did not look at it. He inadvertently selected the OFF position. The engine quit, and could not be restarted. The instructor landed the airplane about 50 yards short of the runway. The main landing gear wheels dug into the snow during landing roll, and the airplane nosed-over.
Probable Cause
FUEL STARVATION DUE TO THE IMPROPER POSITIONING OF THE FUEL TANK SELECTOR BY THE STUDENT PILOT.
