Flight Sequence
During an airplane familiarization flight, the flight instructor (CFI) moved the throttle to idle to simulate an engine failure. The private pilot receiving instruction performed the emergency engine failure procedures, turned the carburetor heat to the on position, and extended the flaps to the 20-degree position. The CFI stated that the private pilot cleared the engine one time during the approach, and she briefed him on the downwind landing. The airplane touched down within the first 1,000 feet of the 2,700-foot-long grass airstrip.
Accident Sequence
The CFI then instructed the private pilot to go-around. According to the CFI, she retracted the flaps to the 10-degree position and, once clear of power lines, retracted the remainder of the flaps. However, the airplane then began losing altitude. The CFI stated that she then took control of the airplane. The private pilot reported that he landed the airplane and relinquished control to the CFI. The CFI applied full power and established a positive rate of climb, and the airplane cleared power lines. The airplane's engine then began losing power, and the airplane began to sink. Subsequently, the airplane contacted trees at the departure end of the airstrip and impacted the ground.
Engine Examination
Examination of the airplane's engine did not reveal any preimpact anomalies that would preclude its operation.
