At approximately 1840 Central tine, the airplane was destroyed during impact with terrain following a loss of control during a landing approach. The Flight Instructor and Student pilot were fatally injured. Visual conditions prevailed. According to witnesses, the wind was reported at about 20 knots, gusting in excess of 25 knots. The airplane was observed to take off and level out. It then made a slight climb before a sharp 180-degree turn was observed. The witnesses stated that the airplane then lost altitude, before climbing back up to about 200-300 feet again, at which time the airplane made a sharp, high-banked turn towards the runway. During the turn the left wing continued to drop, and the airplane descended in a near-vertical attitude then impacted the ground.
