Incident Overview
A multi-engine training flight concluded with a ground impact during a simulated single-engine landing. The accident occurred after the pilot misinterpreted a flight instructor's command regarding engine power, resulting in a loss of control and substantial damage to the aircraft.
Sequence of Events
The pilot and flight instructor had completed approximately two hours of multi-engine flight training. They were performing a "zero thrust, single engine" full stop landing. During the final approach, a sink rate developed, prompting the flight instructor to instruct the pilot to "add a small amount of power to the right operating engine." The pilot misunderstood the instruction as "abort" and applied full power to the right engine, intending to abort the landing. The application of full power caused the airplane to roll left. In response, the flight instructor added right rudder to arrest the roll. However, the left wing struck the ground, and the airplane rotated left on the ground. The impact substantially damaged the airplane's left wing and collapsed all three landing gear.
Pilot Status
Neither pilot was injured in the event.
Mechanical Condition
An examination of the aircraft revealed no mechanical anomalies that would have precluded normal operation.
