Analysis

This balloon flt was part of a rally. The flt departed from a stadium, climbed to 500' and then made a controlled descent and landing. After the next takeoff and climb to about 125' when the burner was turned off the plt noticed that fuel was not flowing to the plt light. While attempting corrective action the balloon cooled and began to descend. The balloon was drifting toward powerlines and upon reaching 50 to 75' AGL, the plt decided to open the vent full and make an emergency landing. During the landing the balloon draped over a fence and the passenger suffered a broken ankle. The pilot stated that it is likely she inadvertently bumped the pilot light valve while working the main fuel valve. She reported that after the accident both the main and pilot fuel systems were checked and found ok.
