Lessons Learned - Inadvertently Excessed Pulse Width Modulator Circuit Card Assemblies (PWM CCA)
Year: 2010
Abstract: Pulse width modulator circuit card assemblies (PWM CCAs), valued at $150,000 each were inadvertently excessed to the KSC excess property storage area. The PWM CCAs were attached to holding fixtures, and were subsequently purchased as scrap metal by a local salvage company. The sole decision criterion for excessing items was usage rate. The computerized logistics system documented the holding fixtures as not being in use. The individuals involved in the excessing process believed that they were only excessing holding fixtures. The holding fixtures were entered as separate items from the PWM CCAs, because the system lacked the capability to document and track integrated components. Programs should identify risks for disposition and excess of hardware, by analyzing all process flows, permit entry and designation of integrated hardware and train material handling personnel by management covering flight hardware handling and identification.
