According to the pilot of the twin-engine airplane, he descended from 7,000 ft and leveled off at 3,000 ft. After leveling off, the fuel quantity indicators fluctuated then showed empty. He recalled that, about 5 minutes after leveling off, the right engine began to run very roughly, so he enriched the right engine's mixture and activated the auxiliary fuel pump. He added that, subsequently, "the right engine failed and the left engine simultaneously began losing power." The pilot declared an emergency with air traffic control, began receiving vectors, and the left engine lost power. The pilot pitched the airplane for best glide distance. He selected the nearest suitable landing area, extended the landing gear and flaps, and landed the airplane in a field. During the landing roll, he turned the airplane to the right to avoid a collision with obstacles, and the nose landing gear bounced several times and separated from the airplane. The airplane sustained substantial damage to the fuselage bulkheads, longerons, and stringers. The pilot believed that, due to his failure to visually check the fuel level, he overestimated the amount of fuel on board. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
