Event Location
Probable Cause
The pilot’s unstabilized approach and delayed application of full throttle for a go-around, which resulted in an uncontrolled descent.
Full Narrative
The pilot of the high performance airplane reported that on his third simulated forced landing, while turning left base to final in a slip, he realized that the airplane was too low, and not aligned with the runway. He applied full throttle to go-around. The airplane responded suddenly by changing attitude, but continued to descend and impacted terrain and the airport perimeter fence. The airplane sustained substantial damage to both wings and the fuselage.
The pilot further reported that the slow airspeed coupled with the unexpected high torque from advancing the throttle during an uncoordinated left turn were factors in the accident.
The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
