Clearly you don't read anything I said that you would require chapter and verse to shut you up and that I did not have that to hand at that moment NOT that I did not know what the EASA regulations are.
The basics of it is that a company can approve anyone that it thinks is fit to do a duplicate or (in EASA speak) independant inspection.
At the moment it is very unusual to find anyone who is not a licenced engineer who has duplicate inspection approval.
A duplicate inspection is a very hard thing to do not so much from a techincal point of veiw but from a human factors stance, the person comes to the inspection knowing that a licenced engineer has already inspected the job and is more likely to start with tha assumtion that all is correct.
If the person with the duplicate inspection approval is a non-licenced junior member of staff and the job has been done by the Chief engineer it is likely that he will feel uneasy about expressing doubts about the job, this is a lot less lightly to happen if a licenced engineer is doing the duplicate inspection as his status in the company will be a lot higher as well as having a lot more experience in engineering.
There is some psyco-babble to discribe this but I cant put my finger on the term right now................... Oh no ! DFC is about to demand that I go on a CRM refresher course!
