In the aerospace industry, maintaining impeccable quality standards is paramount. To achieve this, aerospace companies rely on specialized quality management systems (QMS) that ensure rigorous compliance and continuous improvement. Two widely recognized QMS certifications in the aerospace sector are AS9110 and AS9100. While both certifications share similarities, they differ in terms of their application and focus. In this article, we will explore the distinctions between AS9110 and AS9100, shedding light on their specific requirements and advantages.

Understanding AS9110 Certification

AS9110 is a QMS certification specifically designed for organizations that provide maintenance, repair, and overhaul (MRO) services within the aerospace industry. It is an extension of the ISO 9001 standard, tailored to meet the unique requirements of MRO operations. AS9110 emphasizes the importance of safety, reliability, and regulatory compliance in the maintenance and servicing of aircraft, components, and equipment.

Companies seeking AS9110 certification must demonstrate their ability to effectively manage MRO processes, including maintenance planning, configuration management, risk assessment, and customer satisfaction. This certification enables MRO organizations to enhance their operational efficiency, minimize risks, and build trust with their customers by adhering to industry-specific quality standards.

Understanding AS9100 Certification

AS9100 is a widely recognized QMS certification that encompasses the entire aerospace supply chain. It is based on the ISO 9001 standard but includes additional requirements specific to the aerospace industry. AS9100 places strong emphasis on product safety, traceability, and risk management throughout the entire manufacturing and distribution processes of aerospace products.

To achieve AS9100 certification, aerospace companies must demonstrate their commitment to quality and continuous improvement in areas such as design and development, purchasing, production, and servicing of aerospace products. This certification enables organizations to establish robust quality management systems, mitigate risks, and maintain the highest levels of customer satisfaction.

Key Differences Between AS9110 and AS9100

When comparing AS9110 and AS9100, several notable differences arise:

1. Application Focus AS9110 primarily focuses on organizations providing MRO services, while AS9100 encompasses the broader aerospace supply chain, including design, production, and distribution.

2. Scope of Requirements AS9110 concentrates on maintenance-specific requirements, such as repair and overhaul processes, configuration management, and regulatory compliance. In contrast, AS9100 covers a wider range of activities, including design, production, and servicing.

3. Customer Requirements AS9110 places more emphasis on meeting customer-specific requirements related to maintenance and servicing. AS9100 also prioritizes customer satisfaction but extends to design, manufacturing, and delivery of aerospace products.

4. Certification Benefits AS9110 certification enables MRO organizations to enhance their operational efficiency, improve safety measures, and gain a competitive edge in the maintenance sector. AS9100 certification benefits aerospace companies by strengthening their overall QMS, ensuring product safety, and enhancing customer confidence throughout the supply chain.


While AS9110 and AS9100 are both critical certifications for ensuring quality in the aerospace industry, they have distinct focuses and requirements. AS9110 caters specifically to MRO organizations, emphasizing maintenance-specific processes and regulatory compliance. On the other hand, AS9100 covers the entire aerospace supply chain, encompassing design, production, and servicing activities.

By understanding the differences between AS9110 and AS9100, aerospace companies can make informed decisions about the most appropriate certification for their specific operations. Implementing the right QMS certification not only ensures compliance but also strengthens customer relationships, improves operational efficiency, and enhances overall quality in the dynamic aerospace industry.
