Choosing an Aerospace
Assembly Supplier
What to evaluate when selecting a supplier for aerospace or defense assembly work, from quality certifications to specialized process knowledge.
What should a buyer evaluate when selecting an aerospace assembly supplier?
Selecting an aerospace assembly supplier involves evaluating quality systems and certifications, documented process capability, specification and drawing control, inspection and testing practices, traceability, and experience with the specific process a program requires.
These factors should be confirmed against the requirements of the specific program, not assumed from general marketing claims.
Evaluation Criteria
What to confirm before awarding work
Quality systems and certifications
Confirm the supplier holds relevant aerospace quality certifications, such as AS9100 and ISO 9001, and ask when the certificate was issued and when it expires.
Process capability
Review whether the supplier has documented experience with the specific processes your program requires, such as bearing installation and retention, fastener installation, riveting, or insert installation.
Specification and drawing control
Ask how the supplier manages controlled drawings and specifications, including revision control, to confirm work is performed to the current requirement.
Inspection and testing
Confirm what inspection and testing capabilities the supplier maintains, such as proof-load testing, and what documentation is provided with completed work.
Traceability
Ask how the supplier tracks material, components, and process records back to a specific lot, drawing revision, or work order.
Documentation
Confirm the supplier can provide the certificates of conformance, inspection reports, or First Article Inspection (FAI) documentation your program requires.
Why certifications and documentation matter
Aerospace quality certifications indicate that a supplier's quality management system has been independently assessed. As an example, American Precision Assembly holds ISO 9001:2015 and AS9100D certification (assessed to the AQMS Standard AS9104/1:2012), covering assemblies for the aerospace, military, and commercial aircraft industries.
When evaluating any supplier, ask for the certificate number, certifying body, and current issue and expiration dates rather than relying on a general statement of certification.
