description abstract	Description of Driving Event: While dynatube leak checks were completed, manifolds were vented to ambient pressure. This allowed thrusters to leak. After the third flow, engineer positioned ullage valve (V4) to closed, this caused a pressure spike that ruptured the valve burst disk. The engineer was unaware of the failure, which was found during subsequent testing and data review.
