Documentation maintenance

There is no definitive timeline given for document retention in AS9100, since this will be different from document to document. You need to determine the retention or each document you create, with information coming from customer or legal requirements. For instance, contracts should tell you how long to keep records for that contract, and there are many aviation requirements to keep records for the lifetime of the aircraft. Whereas, some countries have a seven-year retention for financial documents. If you have no legal or contractual requirements telling you how long to keep a specific record, such as older versions of procedures that you have changed, then it is up to you to determine a retention time (we suggest 3 years)
