AS9145 – APQP and PPAP for Aerospace

The aerospace standard AS9145 was released in 2016 and titled “Requirements for Advanced Product Quality Planning (APQP) and Production Part Approval Process (PPAP)”.  Aerospace adopted the Automotive Industry Action Group’s (AIAG) APQP concepts and applied a common-sense approach in fitting these to the Aerospace industry.  While there are some differences, the theme, purpose, and concepts remain the same.

To keep up with requirements for the aerospace industry, simpleQuE attends the AAQG/SAE G14 committee meetings of the America’s group which develops the AS standards.  Over the last several years, we’ve seen many of the Primes and Sub-Primes preparing for the rollout and flow down of these APQP requirements to their suppliers.  Lockheed Martin, Harris, L-3, Rockwell Collins, and others have passed these requirements on to their supply chain in their PO flow down and contract requirements.

What is AS9145?

This AS9145 standard is used as a guideline, and is not an AS standard for certification.  It establishes requirements for performing and documenting APQP and PPAP and integrates with the 9100, 9102, 9103 and 9110 standards. When a customer flows down these APQP requirements, then it’s incorporated into AS9100 audits for certification as customer requirements. It is the same for automotive suppliers.

One of the aerospace enhancements is an APQP maturity model.  The maturity model and rating evaluates the use of APQP and all the associated core tools (PPAP, FMEA, Control Plans, MSA/GR&R, and SPC).  This maturity model and rating system is a way for the customer to assess their supplier’s maturity on the use, implementation, and sophistication of their supplier’s APQP processes.  Ultimately, this provides a risk approach to assessing the need for supplier development with APQP.  Refer to the table below.

What is the difference between PPAP in the automotive versus the aerospace industry?

Instead of the 18 auto industry elements, aerospace has only has 11 components for their PPAPs.

The industry is developing training, materials and tools to help their suppliers, while utilizing the existing automotive core tools from AIAG. The AIAG “blue book” guidelines are referenced as foundational documents for the Aerospace process.
