Analysis

During flt, the plt used fuel from 2 of 4 propane tanks, then switched to the 2nd 2 tanks & started a descent. At aprx 300 ft AGL, he tried to start the burner, but could not get a light because the pilot light was out. He attempted to manually relight the burner with a flint sparker, but the burner would not relight. Subsequently, the balloon struck a metal fence, bounced & hit a tractor. Five of the passengers fell out. The plt & one other passenger were carried another 200 yards into a swampy area. An exam of the fuel sys showed that the pilot light valve was a toggle type switch near the 'fire 2' valve. The plt reported that he could have inadvertently struck & shut off the pilot light valve as he rotated the 'fire 2' valve. When checked, the pilot light & burner operated normally. The 'fire 2' would only light with the flint sparker when the valve was only slightly opened.
