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

THE COMMERCIAL/PILOT RATED PASSENGER SAID THE TAKEOFF WAS UNEVENTFUL UNTIL THE AIRPLANE REACHED AN ALTITUDE OF A FEW HUNDRED FEET. HE STATED THAT HE HEARD A LOUD NOISE THAT SOUNDED LIKE A BACKFIRE AND THE ENGINE LOST POWER. A FORCED LANDING APPROACH WAS MADE TO A SMALL FIELD LOCATED IN A CONGESTED INDUSTRIAL PARK. DURING THE APPROACH, THE LEFT WING OF THE AIRPLANE IMPACTED A TREE. THE AIRPLANE THEN YAWED, THE LEFT WING DROPPED, AND THE AIRPLANE IMPACTED THE TERRAIN. INVESTIGATION REVEALED NO EVIDENCE OF A PREIMPACT MECHANICAL FAILURE. THE TEMPERATURE AND DEW POINT WERE 53 AND 52 DEGREES, RESPECTIVELY. ACCORDING TO ICING PROBABILITY CHARTS, CONDITIONS WERE CONDUCIVE FOR SERIOUS CARBURETOR ICING. THE CARBURETOR HEAT WAS FOUND IN THE 'OFF' POSITION.
