What is AS9145?
AS9145 is the aerospace standard for advanced product quality planning and production part approval. It sets out five phases for launching a part, from planning through product and process design to validation and ongoing production, with deliverables such as the process FMEA, control plan, measurement studies and first article inspection.
AS9145 borrows a lot from automotive APQP and PPAP, but many aerospace suppliers have never run either. Doing it in spreadsheets means building the whole method from scratch.
