Abstract
Returns from three years of desert deployment were disassembled and traced to root cause. Sixty-one per cent of failures resolved to a single connector series whose retention degraded under daily thermal cycling, not to the semiconductors that the original FMEA had ranked highest. The revised FMEA weighting is included.
