The airplane then made a tight left 180-degree turn to final approach for landing. During the turn, the airplane stalled, entered a steep nose down descent, and made at least one-half turn to the left before impacting the ground. The ultralight had just been purchased and was being delivered to the new owner when the accident occurred.
