Lessons Learned - APU Fuel Isolation Valve Assembly
Year: 1992
Abstract: Description of Driving Event:
An APU hydrazine isolation valve assembly was removed and sent to the shipping section of logistics without being properly packaged for safe handling. In addition, there was no Q.A. check sheet and no decontamination tags with safety buy-off as being sniffed at zero parts per million. There was a conditional decontamination tag with the part indicating that it was from a fuel system, and conditionally decontaminated but absorbed or trapped fuel could out-gas. The OPF was called for safety and technical support to come and check out the valve; the valve tested positive for hydrazine and was immediately safed.
