What happened
During a single-engine approach and landing, the flight instructor had set the right engine to zero thrust. The aircraft, a PA-34-200, was on final approach with the landing gear and flaps extended when the student pilot elected to perform a go-around while operating on a single engine.
The go-around maneuver began at an altitude of approximately 50 feet above the ground. During the transition, the left wing rose rapidly. The instructor attempted to apply power to the right engine, but the engine failed to respond. The instructor then took control of the aircraft; however, before control could be stabilized, the airplane drifted to the right of the runway centerline. The right wing struck the ground, causing the aircraft to slide approximately 300 to 400 feet before coming to a stop. The occupants were not injured.
The investigation
The investigation found no evidence of mechanical malfunction in the aircraft's systems.
