At about 1135 Mountain time, the airplane sustained substantial damage when it collided with terrain while maneuvering. The private pilot, who occupied the left seat, and the CFI occupying the right seat sustained fatal injuries. Visual conditions prevailed.
A line service person who assisted the pilot in preparing the airplane for the flight reported the pilot mentioned he and the CFI were going up to practice some maneuvers. Several witnesses reported observing the airplane over the runway in an extremely steep bank angle to the left and in a severely nose-down attitude prior to impact with terrain. Two witnesses reported the airplane was at about 200 to 300 feet agl when it entered the steep descent.
