The aircraft collided with trees during an attempted go-around during a night operation. The pilot had just recently acquired the aircraft and he was accompanied by his wife at the time of the accident. The pilot lacked certification in the aircraft. Witnesses heard the engines stop and start at least once during the go-around followed by the noise of a crash. The pilot stated that everything looked good during the go-around until they reached 300 ft AGL when the aircraft started to vibrate and shortly thereafter collided with trees. The aircraft collided in a steep bank, nose low attitude and cartwheeled. Investigation revealed a difference between the fuel aboard as calculated by the salesmen. By his figures the aircraft should have contained 12 gallons of fuel after the accident and it contained about 54 gallons. About 40 of these gallons were in the left main tank and 14 in the right aux. The rear engine was using the right aux tank. The front engine was on the left main tank, however, no fuel was found in the front engine fuel strainer after the accident.
