## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

WHILE CONDUCTING A LOW APPROACH TO RUNWAY 33 THE INSTRUCTOR TOLD THE TRAINEE TO "GO-AROUND".  APPROXIMATELY 600-700 FEET DURING THE GO-AROUND, THE INSTRUCTOR SIMULATED A LEFT ENGINE FAILURE.  THE TRAINEE COMPLETED THE SIMULATED ENGINE FAILURE CHECKLIST, BUT INSTEAD OF SIMULATING MOVING THE LEFT ELECTRIC FUEL BOOST PUMP TO HIGH, THE TRAINEE ACTUALLY SELECTED THE PUMP TO ?HIGH.?  CONTINUING THE CLIMB THE INSTRUCTOR VECTORED THE TRAINEE FOR A SIMULATED MANUAL ILS APPROACH TO RUNWAY 24.  AT MINIMUMS OR SLIGHTLY ABOVE THE TRAINEE REMOVED THE HOOD, SELECTED THE FLAPS FULL DOWN, MATCHED THE THROTTLES AND CONTINUED FOR A VISUAL LANDING.  THE INSTRUCTOR MOVED THE MIXTURE LEVER TO FULL RICH.  AT 50 FEET THE INSTRUCTOR SAID, ?GO-AROUND.?  THE TRAINEE EXECUTED THE GO-AROUND MANEUVER SELECTING BOTH THROTTLES FULL FORWARD, CONFIRMING THE PROPELLERS AND MIXTURE LEVERS FULL FORWARD THEN SELECTED THE LANDING GEAR AND FLAPS TO THE ?UP? POSITION.  THE AIRCRAFT CONTINUED A DESCENT, ALMOST TOUCHING THE RUNWAY, BEFORE STARTING TO CLIMB.  WHILE CLIMBING THE AIRCRAFT YAWED SIGNIFICANTLY TO THE LEFT, BEGAN DRIFTING LEFT AND STOPPED CLIMBING AT APPROXIMATELY 100 FEET.  THE INSTRUCTOR ASSUMED CONTROL, LOWERED THE LANDING GEAR AND FLAPS, AND INITIATED AN EMERGENCY LANDING IN THE GRASS.  THE AIRCRAFT STRUCK THE GROUND WITH THE LANDING GEAR NOT FULLY EXTENDED AND CAME TO A STOP.
