Per the PPAP manual, submission is required when "Product is re-released after the tooling has been inactive for volume production for 12 months or more." I have yet to contact our registrar for his interpretation. We are struggling whether this means if NO production was run for 12 months or if re-PPAP applies only IF our customer designates the tool as inactive AND 12 months of no production go by. We,internally, take steps to check tooling if it sits idle for a year, but have not been re-submitting PPAPs to our customers. Any similar interpretations out there?
