Abstract:

Each payload standard mix cargo harness (SMCH) must be validated before being installed in the Orbiter. This is because the payload configuration changes with each mission. The Automated Wire Analyzer (AWA) wire tester had been in use for over 20 years and had become obsolete. Its maintenance had become unmanageable and too costly. The benefits of replacing the AWA wire tester were realized immediately. The time required to test harnesses was reduced by 80 to 90 percent. Because the replacement system offered the ability to recall all previously tested harnesses, the test data became more reliable.
