Flight Sequence
During an instructional flight, the instructor (CFI) moved the fuel selector from BOTH to the LEFT tank and reduced the throttle to idle to simulate an engine failure. The student then executed emergency procedures intended to simulate an engine restart, including repositioning the fuel selector to BOTH. The student maneuvered the aircraft toward a selected landing area. At approximately 300 feet above ground level (AGL), the CFI assessed that the student could have landed successfully in the chosen area. The CFI then assumed control of the aircraft and raised the flaps to 20 degrees.
Engine Failure and Forced Landing
During the subsequent climb out at about 400 feet AGL, the engine ceased operating. The emergency checklist was followed, but the engine could not be restarted. A forced landing was made in a field; after touchdown, the aircraft nosed over.
Post-Accident Examination
An examination of the engine revealed no evidence of preimpact part failure or malfunction. When tested after the accident, the engine operated normally up to approximately 1500 RPM, but it was not run at higher RPM due to damage to the propeller. The fuel selector handle was rotated and found to be worn, making the detent difficult to locate.
