The NTSB's narrative final · quoted from the NTSB record

During cruise flight, the balloon encountered a sudden downdraft. The pilot arrested the descent to level flight, but not in time to prevent the bottom of the basket from contacting nearby power lines. The pilot subsequently landed the balloon without further incident. One passenger sustained serious injuries. The pilot reported that there were no preaccident mechanical failures or malfunctions with the balloon that would have precluded normal operation.
