Accident Overview
A certified flight instructor (CFI) was providing flight instruction in takeoffs and landings to a student pilot. During the accident approach, the airplane was at a height of 20 feet over the displaced threshold with power at idle and airspeed at 65 knots. The CFI determined that a go-around was necessary when the airplane was about halfway down the runway.
Go-Around and Engine Response
The CFI took control of the airplane, applied power, and pushed the carburetor heat in simultaneously. The engine sputtered, prompting the CFI to execute a forced landing to the runway. The student pilot reported that on the last landing, "The power was pushed in and the plane did not respond as expected. So we had to land and roll off of the runway."
Forced Landing and Outcome
The airplane departed the runway and nosed over in soft terrain.
Post-Accident Engine Examination
The engine was removed from the airframe and an engine run was conducted. The engine started and operated within its RPM ranges.
Pilot Statements
The CFI reported the sequence of events, including the decision to go around and the engine sputter. The student pilot provided a brief account of the unexpected power response.
