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

SHORTLY AFTER TAKEOFF, THE RIGHT ENGINE LOST POWER. THE PILOT WAS UNABLE TO RESTART THE ENGINE AND THE AIRPLANE WOULD NOT MAINTAIN ALTITUDE. THE PILOT INITIATED A LEFT 180 DEGREE TURN BACK TOWARD THE AIRPORT; HOWEVER, HE REALIZED THAT THE AIRPLANE WAS NOT GOING TO REACH THE RUNWAY, SO HE OPTED TO LAND ON ROUGH TERRAIN. AFTER THE AIRPLANE WAS RETRIEVED, THE ENGINE WAS PREPARED FOR A TEST RUN. IT STARTED AND WAS RUN FOR SEVERAL MINUTES AT VARYING POWER SETTINGS WITH NO EVIDENCE FOUND TO INDICATE A MECHANICAL FAILURE OR MALFUNCTION. DENSITY ALTITUDE WAS ABOUT 8950 FEET.
