Does AS9100D state how long (in Years) internal audit records are to be kept? I have not been able to find it within the as9100D standard, but a customer says records of internal audit results are to be kept for 7 years per AS9100. I understand if my customer requires 7 years then I have to follow that requirement, but they do not require how long, he said they go by the requirement within AS9100, but I don't see in 9.2 anything, am I missing it.
