What happened
During a multi-engine instructional flight, the pilot-under-instruction (PUI) was operating from the left seat while the flight instructor occupied the right seat. The flight was intended to be a simulated engine-out approach, with the right engine set to zero thrust.
As the aircraft reached short final, the airspeed began to decrease. Following instructions from the instructor, the PUI increased power; however, due to insufficient rudder input, the aircraft drifted toward the right. The instructor announced his intention to take control and subsequently did so, at which point the PUI relinquished control.
Because of the low altitude and the stabilized state of the aircraft, the instructor intended to land in the grass adjacent to the runway. During this phase, the PUI grabbed the yoke and pulled back on it while screaming. This resulted in a struggle for control between both pilots. As the aircraft fell below minimum control airspeed, it struck the ground in a high right-angle of bank.
Prior to the accident, the instructor had contacted an examiner to cancel the PUI's scheduled check ride, describing the student as unpredictable and prone to performing unusual actions independently.
