My company is an automotive supplier and we just completed a PPAP which resulted in a failure resulting in all the units being torn down and the components reworked to original dimensional specs. They want to reuse the components in the next PPAP run. Can we do that? I heard that you aren't suppose to use reworked components for PPAP production but I do not see this in the PPAP 4th edit manual. Thank you for any help.

Let us look at the problem from a different angle.
There will be a number of steps for tearing down the components, another number of steps for rework, and more steps for reassembley. So for pushing the reworked material, you will have to include all these steps in your PPAP, and will be rquired to submit revised PPAP. In that case, you will have to go through all these steps in regular production too!?! If you think any customer in his right mind will accept such a product, you have another think coming.
Other alternative is, you submit the reworked parts, without including rework steps in the PPAP. Which perhaps is what your colleagues want to do.( I may be wrong)
That is against ethics, and also fraught with attracting detection at the customer's end, in which case you may get blacklisted. So take your pick
Thank you so much for your answers. The problem is that we cannot find this in the PPAP manual and I have to show my colleages where this is defined so they understand. Do you where it is in the maual? Thank you again.
Jim has given an appropiate reply to this question. Show to your colleagues the requisites for PPAP approval, and ask them wheather the reworked parts qualify or not. Only the correct dimensions(end result) do not satisfy the PPAP, rather the whole manufacturing process is examined under a microscope, before giving the nod of approval.

This IMO is an argument for the sake of argument, which does not hold water. In which manual it is written that you should not supply an inferior part? Do you infer from that to be a permission to supply inferior part? :mg:
