OK this isn't an AQL inspection no matter what you or anyone else calls it.
This is simply an in process inspection that does minimize the amount of rescreening should a defect be found. It also helps minimize the amount of scrap or rework for systematic failures where all product has a defect due to a machine failure (for example). It's may be a smart plan (although without further detailsl of the process and what can go wrong I can't say for sure). It is definitely too large a sample size although the frequency isn't bad. I would probably go with 5 to 10. But not an AQL type which is really intended for 'randomly' occurring defects. This can be statistically justified to an auditor as well since it makes common sense.
However, for any kind of real release plan that is based on the ANSI standard you need TO START WITH WHAT AQL YOU NEED. Then you select your confidence level if different from the standard of 95%. Then you select your sample size based on the lot size for the AQL and confidence level.
What AQL do you want? Remember that the AQL is the defect rate that you will accept 95% of the time if it is present. You cannot have a 0% defect rate...
