Narrative:

Simulated right engine failure on downwind leg for runway 35. Student handled the failure by using appropriate checklist. When landing assured, lowered gear/flaps for landing. Student flared at a higher than normal height causing the aircraft to land hard. Simultaneously student elected to go around using left throttle only. Aircraft veered 30 degrees off runway heading toward a bean field. I elected to abort the go around by closing the throttles and bringing the aircraft to a stop instead of trying to continue. I think one of the things that caused the student to use the left engine only during the attempted go around is that when you simulate an engine failure the student only uses the throttle of the gear engine during the exercise (the other one is 'dead,' and thus is not moved after being set for a simulated engine failure). Student does not like the landing and throws the left one into full power--the one his hand is on during the landing and the rest is history. From now on I will stress during a single engine landing that all students confirm closing both throttles and continue to keep their hand on both till a full stop on the runway.

Title: MULTI-ENGINE TRAINING, SINGLE ENGINE APCH. STUDENT DECIDES TO ABORT LNDG BUT ADVANCES 'GOOD' ENGINE ONLY. RWY EXCURSION INTO FIELD.

Narrative: SIMULATED RIGHT ENG FAILURE ON DOWNWIND LEG FOR RWY 35. STUDENT HANDLED THE FAILURE BY USING APPROPRIATE CHKLIST. WHEN LNDG ASSURED, LOWERED GEAR/FLAPS FOR LNDG. STUDENT FLARED AT A HIGHER THAN NORMAL HEIGHT CAUSING THE ACFT TO LAND HARD. SIMULTANEOUSLY STUDENT ELECTED TO GO AROUND USING LEFT THROTTLE ONLY. ACFT VEERED 30 DEGS OFF RWY HDG TOWARD A BEAN FIELD. I ELECTED TO ABORT THE GAR BY CLOSING THE THROTTLES AND BRINGING THE ACFT TO A STOP INSTEAD OF TRYING TO CONTINUE. I THINK ONE OF THE THINGS THAT CAUSED THE STUDENT TO USE THE LEFT ENG ONLY DURING THE ATTEMPTED GAR IS THAT WHEN YOU SIMULATE AN ENG FAILURE THE STUDENT ONLY USES THE THROTTLE OF THE GEAR ENG DURING THE EXERCISE (THE OTHER ONE IS 'DEAD,' AND THUS IS NOT MOVED AFTER BEING SET FOR A SIMULATED ENG FAILURE). STUDENT DOES NOT LIKE THE LNDG AND THROWS THE LEFT ONE INTO FULL PWR--THE ONE HIS HAND IS ON DURING THE LNDG AND THE REST IS HISTORY. FROM NOW ON I WILL STRESS DURING A SINGLE ENG LNDG THAT ALL STUDENTS CONFIRM CLOSING BOTH THROTTLES AND CONTINUE TO KEEP THEIR HAND ON BOTH TILL A FULL STOP ON THE RWY.
