Investigator assessment
Analysis narrative
The pilot of the balloon reported that, during the approach to the landing area, the balloon descended faster than anticipated while crossing over powerlines. Subsequently, the balloon collided with one of powerlines, which resulted in substantial damage to one of the frame’s aluminum upright tubes. The pilot reported that there were no preaccident mechanical malfunctions or failures with the balloon that would have precluded normal operation.
