Lessons Learned – SWIFT Power Control Board Harness Wire Reversal
Year: 2004
Abstract: Abstract:
Serious damage to an instrument's heater control electronics resulted from incorrect wiring within the interface harness. Efforts to expedite the I&T schedule, incomplete documentation and reduced QA involvement were identified as contributing factors; however, risks were expected to be mitigated by the Safe-to-Mate procedure, which was expected to verify compliance with the ICD. These "time saving" decisions and acceptance of excess risk resulted not only in damage to the instrument but also a 4-month schedule delay.
