What happened
During a flight training session near Lake Elsinore, California, the instructor pilot (CFI) intentionally shut down the left engine and feathered the propeller of a PA-34-200 to demonstrate single-engine procedures and performance to a student.
Following this demonstration, the student was instructed to perform a single-engine landing. However, the student approached the final approach at an excessive speed and altitude. In an attempt to correct the approach, the student initiated a go-around, but the aircraft failed to establish a positive rate of climb.
The CFI took control of the aircraft to assist, but was also unable to achieve a sufficient rate of climb to clear power lines situated at the end of the runway. To avoid the wires, the CFI descended the aircraft to fly underneath them. While the aircraft eventually entered a positive rate of climb following this maneuver, it did not gain enough altitude to clear houses located in the flight path. The CFI subsequently elected to perform a straight-ahead landing.
There were no injuries reported, and there were no mechanical failures or malfunctions reported with the aircraft prior to the accident.
