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

After departing the runway, the flight instructor felt a sudden power surge and yaw; however, he was unable to identify which engine was malfunctioning. After verifying proper engine control positions, he took control of the airplane from the student. He then retracted the landing gear to lessen the aerodynamic drag, and continued the climb, but the airspeed decayed towards the minimum controllable airspeed. He subsequently elected to perform a forced landing. During the landing, the airplane was substantially damaged. A postaccident examination of the airplane revealed no evidence of mechanical failure or malfunction.
