Description of Driving Event:
During servicing of the oxidizer on the forward reaction control system (FRCS), a ground half quick disconnect (QD) failed. The failure mode was such that an open flow path was created to the outside of the QD and 15 to 20 gallons of oxidizer (N2O4) flowed overboard prior to isolating the flow sources. The failure of the ground-half QD was attributed to an accumulation of iron nitrate lodged between the probe and the dynamic head. The presence of iron nitrate was traced to contaminated fuel.
