During a training flight, a CFI simulated an engine failure by reducing power on the right engine. After student responded and power was restored, directional control was lost during re-initiated takeoff roll, leading to a collision with rocks and landing gear damage.

Incident Overview

A training flight for a single-engine-rated pilot was in progress when the certified flight instructor (CFI) introduced a simulated engine failure. To create the simulation, the CFI reduced power on the right engine during the takeoff roll. The student correctly responded by reducing power on the left engine. Following this response, power was restored to both engines, and the takeoff roll was re-initiated.

Loss of Control and Collision

Shortly after re-initiating the takeoff, directional control of the airplane was lost. The aircraft departed the right side of the runway and subsequently collided with a pile of rocks. The impact resulted in the nose and right main landing gear being sheared off.

Aftermath

The aircraft sustained damage to its landing gear components. No information regarding occupants, injuries, or other damage was provided in the source.
