The IAQG states that its 9100 certification scheme is designed to harmonize aerospace quality management certification globally and support recognition of certifications within the aerospace supply chain.
ISO 9001 vs AS9100 for Aerospace
A common question is whether an aerospace company should obtain ISO 9001 certification or AS9100 certification.
ISO 9001 is a general quality management system standard applicable to organizations across industries. It provides a framework for managing processes, customer requirements, performance, risks, and continual improvement.
AS9100, on the other hand, is specifically designed for aviation, space, and defense organizations. According to IAQG, the standard includes ISO 9001-based requirements supplemented with additional requirements developed for the aerospace and defense industry.
Therefore, an organization should select its certification based on its products, services, customer expectations, supply-chain requirements, and applicable industry requirements.
For an aerospace supplier seeking certification recognized through the IAQG certification scheme, AS9100 may be the more relevant aerospace-specific quality management standard.
What Is AS9100 Certification?
AS9100 certification is certification to an aerospace quality management system standard for aviation, space, and defense organizations.
The standard can be used by organizations at different levels of the aerospace supply chain. IAQG notes that the standard is intended to standardize quality management system requirements across the global aviation, space, and defense supply chain.
AS9100 builds on the principles and requirements of ISO 9001 while adding aerospace-specific considerations.
These additional areas include topics such as:
IAQG materials specifically identify product safety, counterfeit parts prevention, risk, awareness, human factors, and configuration management among the aerospace-specific areas addressed in the 9100 requirements.
Who Needs ISO Certification for Aerospace?
ISO Certification for Aerospace may be relevant to a wide range of organizations involved in the aerospace supply chain.
Aerospace Manufacturers
Manufacturers producing aircraft components, aerospace assemblies, precision-machined parts, structures, systems, and other products can benefit from a structured quality management system.
Aerospace Component Suppliers
Suppliers providing components or materials to aerospace manufacturers may need to demonstrate compliance with specific quality management requirements.
Aviation and Aerospace Service Providers
Organizations providing engineering, inspection, testing, technical, or other support services may also need appropriate quality management systems depending on their activities and customer requirements.
Maintenance Organizations
Organizations involved in aviation maintenance may consider the applicable 9110 standard. IAQG identifies 9110 as the QMS standard for aviation maintenance organizations.
Aerospace Distributors
Organizations distributing aviation, space, and defense products may consider 9120, which IAQG identifies as the quality management standard for aviation, space, and defense distributors.
Key Benefits of Aerospace ISO Certification
1. Improve Product Quality
A structured QMS helps organizations establish controlled processes for manufacturing, inspection, testing, and delivery.
2. Strengthen Process Control
Defined procedures and responsibilities can help organizations maintain consistency across different departments and production stages.
3. Improve Risk Management
Aerospace organizations operate in environments where risks must be carefully identified and controlled. Aerospace quality standards place significant emphasis on risk-based processes.

ISO Certification Process for Aerospace Companies
The certification process depends on the applicable standard, organizational scope, complexity, and certification arrangement. Generally, an organization can follow these steps.
Step 1: Identify the Applicable Standard
Determine whether ISO 9001, AS9100, AS9110, AS9120, or another applicable standard is appropriate.
Step 2: Define the Certification Scope
Identify the products, services, locations, departments, and processes that will be covered by the management system.
Step 3: Conduct a Gap Assessment
Review current processes against the requirements of the selected standard. This helps identify areas that need improvement.
Step 4: Develop and Update Processes
Establish appropriate procedures, policies, quality objectives, risk controls, supplier controls, inspection processes, and records.
Step 5: Implement the QMS
Employees should follow the established processes, maintain required records, and understand their responsibilities.
Step 6: Conduct Internal Audits
Internal audits help identify nonconformities and improvement opportunities before the certification audit.
Step 7: Management Review
Top management reviews the effectiveness and performance of the quality management system and determines appropriate actions.
Step 8: Certification Audit
An independent certification body conducts the applicable audit. For certification under the IAQG scheme, organizations select an appropriate accredited certification body participating in the scheme. IAQG states that the certification body audits according to applicable requirements including ISO/IEC 17021-1, IAQG 9104/1, and IAQG 9101.
Importance of Traceability in Aerospace
Traceability is particularly important in aerospace manufacturing because organizations may need to identify materials, components, production activities, inspection records, and other information associated with a product.
