Keep in mind that if you need certification (such as to ISO 9001) for commercial customers you can have separate scopes for ISO 9001 and AS9100. If you don't have a separate ISO 9001 certificate and your AS9100 scope doesn't include the processes for commercial products, then the auditor shouldn't look at those processes and you won't be able to claim conformity to any standard for them.4.3 Determining the Scope of the Quality Management System
The organization shall determine the boundaries and applicability of the quality management system to establish its scope.
When determining this scope, the organization shall consider:
a. the external and internal issues referred to in 4.1;
b. the requirements of relevant interested parties referred to in 4.2;
c. the products and services of the organization.
