description abstract	Description of Driving Event: A counterbalance cable had become disengaged from the upper support beam pulley during assembly operations. This was caused by the work scaffold (used to access the upper beam area) making contact with the counterweight. The tension in the cable was relieved, allowing it to slip from the pulley groove. When the load was reestablished, tension was reapplied to the counterbalance cable, pulling the weight free and allowing it to fall.
