Right engine failure during single-engine practice approach

Casualties unknown • Chino, CA, US

An aircraft experienced a right engine failure during a simulated single-engine ILS approach, resulting in the right wing tip striking the ground.

What happened

During a training flight, a student pilot was conducting a practice single-engine ILS approach to runway 26. The right engine had been intentionally set to zero thrust for the maneuver. As the aircraft approached the runway, it was high and had drifted over the right edge of the runway.

In response to the aircraft's position, the flight instructor commanded a go-around. The student attempted to execute the maneuver by advancing both throttles; however, the right engine failed to respond. This loss of power caused the aircraft to yaw and roll to the right. During the excursion, the right wing tip struck the ground, causing the aircraft to cartwheel before coming to a stop.

The investigation

The right engine was removed from the aircraft for inspection. A FAA certified airframe and power plant mechanic examined the engine, but the examination revealed no discrepancies.
