EMU Hazard Report did not identify the hazard. ECFT-3.2.1.1

FMEA/CIL did not effectively describe the behavior of w ater entering the vent loop from the PLSS. ECFT-3.2.1.1.1

No one applied our know ledge of the physics of w ater behavior in zero g to w ater coming from the PLSS vent loop ECFT-3.2.1.1.1.1

FMEA/CIL did not effectively quantify the amounts of w ater entering the vent loop from the PLSS. ECFT-3.2.1.1.2

FMEA/CIL did not undergo thourough review and update periodically. ECFT-3.2.1.1.1.2

ISS program FMEA/CIL requirement did not require complete FMEA/CIL periodic update. ECFT-3.2.1.1.1.2.1

Program cut funding

ECFT-3.2.1.1.1.2.2

Community had lost sight of the value of the FMEA/CIL effort. ECFT-3.2.1.1.1.2.2.1

Figure 3-59 Causes and Contributing Factors under ECFT 3.2.1.1 ECFT-3.2.1.1 – EMU Hazard Report did not identify the hazard. (Intermediate Cause 16) Supporting Evidence: See ECFT-3.1.2.1.1 branch, EMU Hazard Report did not identify the hazard, for discussion of this and lower level causes.
