What happened
During the initial climb-out from the airport, the flight instructor turned off the right engine fuel selector to simulate an engine failure. The student pilot performed the required engine-out emergency checklist, which involved feathering the right engine propeller. Following the checklist, the instructor directed the student to re-enter the right traffic pattern.
While on approach, the student pilot overshot the final approach course. At this time, the instructor observed that the left main landing gear down light was not illuminated. The instructor took control of the aircraft and attempted a single-engine go-around. However, the aircraft failed to climb. To avoid further complications, the instructor elected to land the plane on a street. During the landing sequence, the aircraft collided with a sign and a pickup truck before coming to a stop.
All occupants were not injured.
