NTSB analysis

According to the Federal Aviation Administration inspector who traveled to the scene, the pilot was participating in a hot-air balloon competition. The pilot called her ground crew while en route and reported that all three propane tanks were empty. The pilot attempted a forced landing to a parking lot and bounced three times before the balloon came to rest. She stated that the balloon's propane tanks had been filled the night prior to the accident flight and contained 30 gallons of fuel. The burner and fuel system consisted of three fuel tanks designated "master," "slave one," and "slave two." She advised that she flew on slave one until it was exhausted. She verified that the master tank contained fuel, then flew on slave two until it contained approximately 15 percent fuel remaining. Upon switching back to the master tank she noted that for an unknown reason, it too now contained approximately 15 per cent fuel remaining. She began looking for a suitable place for a forced landing. The basket sustained minor damage and the balloon envelope was not damaged. The pilot sustained a broken leg. An examination of the balloon systems revealed no anomalies.
