I was on a training flight with a 200 hour private pilot (instrument rated). We had briefed about engine failures on the runway in a classroom situation and in the aircraft before rolling onto the runway. I informed that we would be practicing one since it was the first time. We held our brakes until showing everything was operating normally. At 20' of mp, released brakes. Applied the rest of the throttle. We were at approximately 45 KTS ind when I chopped the right engine. The student was not responding even when I said retard throttle. I looked down to make sure my hand was still on the left mixture. We were drifting to the right and I was ready to chop the other engine. As I had glanced down the student decided to use rudder to correct. The student being distressed at this time applied close to full right rudder. As I looked up we were 90 degrees to center line and about to go off the runway. I chopped the left mixture and stomped left rudder. We did go off the right side of the runway but ended up parallel with my rudder correction. I held back pressure on the yoke until we came to a stop so that we wouldn't damage propellers or gear. We came to a stop and shut down. We requested ground assistance from our maintenance facility over tower. The aircraft was fine and so was the student and myself. The incident happened very quickly and I reacted as quickly as possible. Callback conversation with reporter revealed the following: minimum control speed was calculated at 70 IAS. Student had been briefed to close both throttles if any problem developed on takeoff roll. Cut the mixture on the right engine and the student panicked and hit the wrong rudder compounding the problem. Analyst suggested maybe just retarding the throttle would be enough for a simulated failure. Student had been fairly competent on single engine airwork. Instrument had a rechk with flight standards and the student qualified with a MEL rating.

Title: MINIMUM EQUIPMENT LIST TRAINING FLT RESULTED IN RWY EXCURSION DURING ENGINE FAIL ON TKOF SIMULATION.
Narrative: I WAS ON A TRNING FLT WITH A 200 HR PVT PLT (INSTRUMENT RATED). WE HAD BRIEFED ABOUT ENG FAILURES ON THE RWY IN A CLASSROOM SITUATION AND IN THE ACFT BEFORE ROLLING ONTO THE RWY. I INFORMED THAT WE WOULD BE PRACTICING ONE SINCE IT WAS THE FIRST TIME. WE HELD OUR BRAKES UNTIL SHOWING EVERYTHING WAS OPERATING NORMALLY. AT 20' OF MP, RELEASED BRAKES. APPLIED THE REST OF THE THROTTLE. WE WERE AT APPROX 45 KTS IND WHEN I CHOPPED THE RIGHT ENG. THE STUDENT WAS NOT RESPONDING EVEN WHEN I SAID RETARD THROTTLE. I LOOKED DOWN TO MAKE SURE MY HAND WAS STILL ON THE LEFT MIXTURE. WE WERE DRIFTING TO THE RIGHT AND I WAS READY TO CHOP THE OTHER ENG. AS I HAD GLANCED DOWN THE STUDENT DECIDED TO USE RUDDER TO CORRECT. THE STUDENT BEING DISTRESSED AT THIS TIME APPLIED CLOSE TO FULL RIGHT RUDDER. AS I LOOKED UP WE WERE 90 DEGS TO CENTER LINE AND ABOUT TO GO OFF THE RWY. I CHOPPED THE LEFT MIXTURE AND STOMPED LEFT RUDDER. WE DID GO OFF THE RIGHT SIDE OF THE RWY BUT ENDED UP PARALLEL WITH MY RUDDER CORRECTION. I HELD BACK PRESSURE ON THE YOKE UNTIL WE CAME TO A STOP SO THAT WE WOULDN'T DAMAGE PROPS OR GEAR. WE CAME TO A STOP AND SHUT DOWN. WE REQUESTED GND ASSISTANCE FROM OUR MAINT FAC OVER TWR. THE ACFT WAS FINE AND SO WAS THE STUDENT AND MYSELF. THE INCIDENT HAPPENED VERY QUICKLY AND I REACTED AS QUICKLY AS POSSIBLE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: MINIMUM CTL SPD WAS CALCULATED AT 70 IAS. STUDENT HAD BEEN BRIEFED TO CLOSE BOTH THROTTLES IF ANY PROB DEVELOPED ON TKOF ROLL. CUT THE MIXTURE ON THE RIGHT ENG AND THE STUDENT PANICKED AND HIT THE WRONG RUDDER COMPOUNDING THE PROB. ANALYST SUGGESTED MAYBE JUST RETARDING THE THROTTLE WOULD BE ENOUGH FOR A SIMULATED FAILURE. STUDENT HAD BEEN FAIRLY COMPETENT ON SINGLE ENG AIRWORK. INSTR HAD A RECHK WITH FLT STANDARDS AND THE STUDENT QUALIFIED WITH A MEL RATING.
