Lessons Learned – Flight Hardware Damage Due to Inadequate Test Planning and Insufficient QA Involvement (2001)
Year: 2002
Abstract: Abstract:
Encoder channels on 44 MER motors were damaged during test due to an improperly inspected cable, lack of safe-to-mate provisions, inadequate test coverage by QA, and failure to verify encoder function following the first of the 44 tests.
Recommendations included the need for approved test plans, completion of operational safety action items, first item witnessing by QA, and comprehensive functional checks after testing of the first item.
