Author by:Precision Turned Parts Supplier and CNC Machining Parts Manufacturer -Maijin Metal


AS9100 is a globally recognized quality management standard specifically tailored for the aerospace industry. It provides a comprehensive framework that assists organizations in establishing and maintaining effective quality management systems. With stringent requirements and a focus on continuous improvement, AS9100 is essential for aerospace companies seeking to ensure the integrity, safety, and reliability of their products and services. In this article, we will delve into the various aspects of AS9100 and explore its significance in the aerospace industry.

What is AS9100?

AS9100 is an internationally recognized quality management standard devised by the International Aerospace Quality Group (IAQG) in collaboration with major aerospace manufacturers. It was derived from the ISO 9001 standard but includes additional requirements specifically tailored for the aerospace sector. AS9100 comprises a set of guidelines and best practices that enable organizations to enhance their quality management systems, drive efficiency, and meet the stringent demands of the aerospace industry. Compliance with AS9100 demonstrates an organization's commitment to customer satisfaction, product safety, and continuous improvement.

AS9100 certification encompasses the entire spectrum of aerospace operations, including the design, development, production, installation, and maintenance of aerospace products. It covers a broad range of stakeholders, including manufacturers, suppliers, distributors, and service providers, ensuring consistent quality throughout the supply chain.

The Benefits of AS9100 Certification

AS9100 certification offers numerous benefits for organizations operating in the aerospace industry. Let's explore some of the key advantages below:

1. Enhanced Customer Confidence: AS9100 certification is highly regarded in the aerospace sector and is often a prerequisite for engagement with major customers. Holding this certification enhances customer confidence, demonstrating an organization's commitment to meeting stringent quality standards.

2. Operational Excellence: AS9100 provides a robust framework for organizations to streamline their processes, reduce waste, and improve overall operational efficiency. The standard emphasizes risk management, root cause analysis, and corrective action, ensuring organizations address potential issues before they escalate.

3. Improved Product Quality: AS9100 places a strong emphasis on quality throughout the entire product lifecycle. By implementing rigorous quality management practices, organizations can ensure the reliability, safety, and performance of their products, ultimately delivering higher customer satisfaction.

4. Compliance with Regulatory Requirements: The aerospace industry is subject to stringent regulatory requirements to ensure the safety and security of air travel. AS9100 helps organizations meet and exceed these requirements, ensuring compliance with aviation authorities and regulatory bodies worldwide.

5. Supply Chain Optimization: AS9100 certification is often a prerequisite for becoming a supplier to major aerospace manufacturers. By achieving certification, organizations can access a broader customer base and establish themselves as reliable partners within the aerospace supply chain.

Implementing AS9100: Key Requirements and Steps

Implementing AS9100 requires a systematic approach that involves several vital steps. Let's explore these steps in detail:

1. Management Commitment: The first step towards AS9100 certification is the commitment of top management. This commitment involves allocating necessary resources, establishing quality objectives, and ensuring the integration of the quality management system into the organization's strategic direction.

2. Gap Analysis: Conducting a gap analysis helps assess the current state of the organization's quality management system against the requirements of AS9100. This analysis identifies areas of non-compliance and serves as a basis for developing an implementation plan.

3. Documentation Development: AS9100 requires organizations to develop a comprehensive set of documentation, including a quality manual, procedures, work instructions, forms, and records. These documents outline the processes, responsibilities, and controls necessary to achieve and maintain compliance.

4. Implementation and Training: Once the documentation is in place, organizations must implement the quality management system by integrating the prescribed processes and practices. Additionally, training programs should be conducted to ensure employees are familiar with the requirements of AS9100 and their roles within the system.

5. Internal Audit: Internal audits are a vital component of AS9100, allowing organizations to evaluate the effectiveness and compliance of their quality management system. Internal auditors assess processes, identify non-conformities, and make recommendations for improvement.

6. Management Review: Regular management reviews enable top management to assess the performance of the quality management system and identify areas for improvement. These reviews involve evaluating key performance indicators, customer feedback, internal audit results, and any emerging risks or opportunities.

7. Certification Audit: The final step towards AS9100 certification is the certification audit conducted by an accredited third-party certification body. This audit involves a thorough assessment of the organization's compliance with the requirements of AS9100. Successful completion of the audit results in the organization receiving an AS9100 certificate.

AS9100 and Continuous Improvement

AS9100 places a strong emphasis on continuous improvement, a fundamental principle in quality management. The standard encourages organizations to adopt a proactive approach to identify opportunities for improvement, implement corrective actions, and streamline processes.

Continuous improvement within the AS9100 framework is achieved through various tools and techniques, including:

1. Lean Six Sigma: Utilizing Lean and Six Sigma methodologies enables organizations to eliminate waste, reduce variation, improve process efficiency, and enhance overall product quality.

2. Statistical Process Control (SPC): SPC is a statistical tool that monitors and controls key process parameters, ensuring consistency and predictability. It helps organizations identify potential issues early on, enabling them to take corrective action promptly.

3. Root Cause Analysis: Root cause analysis is a systematic approach to identify the underlying causes of non-conformities or problems within the organization. By addressing the root causes, organizations can prevent recurrence and drive continuous improvement.

4. Risk Management: AS9100 requires organizations to implement a robust risk management process to identify and mitigate risks throughout the product lifecycle. This proactive approach minimizes the likelihood of failures and enhances overall product reliability.


AS9100 plays a crucial role in the aerospace industry, ensuring the highest levels of quality, safety, and reliability in aerospace products and services. By adhering to the requirements of AS9100, organizations can enhance customer satisfaction, drive operational excellence, and thrive in a highly competitive industry. The implementation of AS9100 brings numerous benefits, including improved product quality, enhanced customer confidence, regulatory compliance, and supply chain optimization. Moreover, AS9100 fosters a culture of continuous improvement, enabling organizations to stay ahead of evolving challenges and deliver excellence in the aerospace sector.
