Narrative:

In preparation for a multi-engine check ride, the instructor closed the mixture lever to simulate an engine failure on takeoff. The airplane had accelerated to approximately 30-40 mph. The airplane swerved to the left and departed the runway, ultimately leaving the edge of an asphalt roadway causing minor damage to the airplane. The student was not prepared for this maneuver. It had not been a part of his training and the instructor did not discuss this possibility immediately prior to the flight. It would be helpful to the student to have some experience of losing an engine on takeoff, knowing in advance that it was going to happen -- at least the first time.
