Lessons Learned - Power Reactant Storage and Distribution (PRSD) Pod Latching Mechanism
Year: 1992
Abstract: Description of Driving Event:
The QD/filter assemblies are designed to provide a disconnected interface and remove all solid particles from the servicing fluids, which exceed 25 microns in size. The system supports the required operating pressures, contaminant capacities and rated flows. A scupper to support the pod has not been provided for Dryden Flight Research Center. This mishap was caused by a worn or deformed stop pin in the pod latching mechanism. The worn pin allows the latching dog to rotate past the mate position to the demate position. Failure has occurred on several occasions.
