Description of Driving Event:

Post launch checkout and semi-annual GOX vent arm maintenance requires technicians to service the GOX vent arm upper hinge and associated flexhoses. The GOX vent arm upper hinge cover panel must be removed to gain access to the hinge for inspection and maintenance. Once the hinge cover panel is removed, it must be maneuvered past the upper hinge support structure. The configuration requires technicians to perform this task at unprotected heights. Because there are no work platforms or approved tie-off points where a safety lanyard/harness can be attached, technicians are at risk of a 255-foot fall.
