The NTSB's narrative final · quoted from the NTSB record

The flight instructor reported that, shortly after the student pilot conducted the takeoff, she noticed an uncommanded yaw, and she then took control of the airplane. The flight instructor started to land straight ahead, lowered the nose, and reduced power, but then she decided that insufficient runway remained to land, so she initiated a go-around. The airplane rolled sharply right and then descended in an uncontrolled inverted attitude, impacted the ground, and struck a parked airplane. The airplane fuselage and wings were substantially damaged from impact and partially consumed by the postcrash fire. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
