What happened
The incident occurred while a certified flight instructor and a dual student were conducting practice touch-and-go landings at an airport. During the landing roll phase of one such attempt, the dual student released the flight controls. The certified flight instructor was unable to regain control before the airplane veered off the right side of the runway. The aircraft then rolled down a ravine into a wooded area and collided with trees.
