What is AS9100 Work Transfer?


Work Transfer Definition:

The movement of the work (products and associated activities) from one manufacturing site to another.


Work transfer impacts several areas of AS9100D (Click to view flow chart above) and it is important to consider and mitigate risk when changing an aspect of a manufactured component.


Examples of Work Transfer:

  • Customer (organization) to supplier (Make to Buy)
  • Supplier to customer (organization) (Buy to Make)
  • Change from Supplier A to Supplier B
  • Change of site at Supplier A

The above types are equally applicable to sub-tier suppliers.

  • Capacity
  • Procurement strategy (e.g., Need for second source to secure the supply chain)
  • Cost Reduction
  • Performance improvements
  • New Technology

More information on Work Transfer:

The IAQG Supply Chain Management Handbook (SCMH) provides more information on this, including some forms for each step of the process as outlined here:


The aviation industry oftentimes changes the source of supply or manufacturing of a component, component package, or assembly within the company or its external supply chain. Movement of work from one site to another, whether internal or external, is considered Work Transfer. When work transfer is not properly managed issues regarding time and quality arise.

IAQG has created a 7 section handbook. Section 7.1 discusses work transfer management.

It is divided into 4 subsections:

  • 7.1.1: Work Transfer Management Introduction
  • 7.1.2: Work Transfer Management Guidance
  • 7.1.3: Work Transfer Management Worksheet Templates and Checklist
  • 7.1.4: Work Transfer Management Worksheet and Checklists
