I think the problem is that when an anomaly is found when conducting a dup. its usually sorted out there and then with no additional reporting action, leading those above us to believe that nothing is ever found whilst conducting these inspections so they are therefore a waste of time and costly. Of course we know otherwise don't we? I must admit that in all the years I've been doing them I've never uncovered the obvious - like a missing split pin or cross connected control but have found other problems. Such as incorrect interpretation of the MM, lack of knowledge of SBs etc, fouling of systems on adjacent systems or structure, incorrect routing, lack of understanding of how a system interacts with other systems leading to ommission of functional checks, etc. I could go on but I'm sure you get my drift. The duplicate inspection is vital to safety and any attempt to discontinue it should be opposed. I assume that as we haven't heard anything recently the idea has been binned.
