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

AFTER 30 MINUTES OF LOCAL FLIGHT, ON A DARK NIGHT, THE PILOT INCREASED THE THROTTLE SETTING AFTER SELECTING APPROACH FLAPS. THERE WAS NO RESPONSE FROM THE ENGINE. A FORCED LANDING WAS INITIATED AND THE AIRCRAFT COLLIDED WITH TREES AND TERRAIN. A SUBSEQUENT INVESTIGATION OF THE ENGINE, FUEL SUPPLY, MAGNETOS AND INDUCTION SYSTEM REVEALED NOTHING WHICH WOULD HAVE PREVENTED THE ENGINE FROM DEVELOPING NORMAL POWER.
