Accident Sequence
During a single-engine approach and landing, the certified flight instructor (CFI) set the right engine to zero thrust. On final approach with landing gear and flaps extended, the student pilot elected to perform a go-around on a single engine. The go-around was initiated at approximately 50 feet above ground level. Subsequently, the left wing rose quickly, and the CFI attempted to increase power on the right engine. The engine did not respond, prompting the CFI to take control of the airplane. Before the CFI could regain full control, the airplane drifted to the right of the runway centerline. The right wing struck the ground, and the airplane slid approximately 300 to 400 feet before coming to rest.
Investigation Findings
The investigation did not disclose any evidence of malfunction. According to the PA-34-200's flight manual, a single-engine go-around is not recommended, and the sudden application of power during single-engine operation makes control of the airplane more difficult.
