Human Factors
Upon completion of run up; engine failure on runway scenario was briefed; as well as engine fail scenarios after takeoff. We continued taxi to Runway XXL. I took control of radios; got takeoff clearance from Tower; Student completed final pre-takeoff items. Once aligned with runway; student smoothly applied full power. Once the aircraft reached full power; I cut the power lever on the left engine; to simulate an engine failure. Student became confused by sudden left yaw; and lost control of the aircraft. I repeatedly said; 'abort' 'abort.' I was unable to apply any brake due to a lack of brakes on instructor side. (Brakes only installed on left side.) Student confused and flustered; returned idle power lever to full position. I loudly said 'my controls' 'my controls.' Student then passed me the controls. Once he let go of the control wheel; the aircraft ascended into ground effect; albeit at too slow a speed. I promptly reduced power; and the plane quickly descended to the runway in a slight left bank attitude; and hit the surface; when I believe the gear collapsed; and the aircraft skidded to the left edge of the runway.
After the run up we briefed for takeoff and aborted simulated engine failure procedure; then when we were on the runway I apply full power and after that my instructor cut off the left throttle and after that the aircraft started going to the left side. I lost control of the airplane and then my instructor said I have control and I said you have control and then when he took the controls; the airplane lifted off in ground affect and my instructor try to control the airplane and then the left wing touch the ground and then sliding the airplane over the runway until stop in the grass and then my instructor cut off master and fuel pump and the selector fuel off and then we evacuated the airplane.
PA-30 flight instructor reported that a student lost control of the aircraft during takeoff; resulting in a gear collapse and damage to the aircraft.
