AS/EN 91XX Standard

Aerospace Management System Certification

Aerospace Management System Certification

Within the aviation, space and defence (ASD) industry, maintaining high safety levels is the foremost challenge. Even the smallest flaws in products or services can have fatal consequences. This has led to high expectations for quality, safety and reliability of parts, systems and services, which your company must achieve across the entire ASD supply chain. Every organisation working in the ASD industry must therefore demonstrate its commitment to safety ,quality and reliability.

What is AS/EN 91XX?

The AS/EN 91XX (AS/EN 9100, AS/EN 9110, and AS/EN 9120) quality management systems are based on ISO 9001, with specific requirements for aviation, space, and defence industries. Published by the International Aerospace Quality Group (IAQG), the AS/EN 91XX standards unify various competing quality documentation and requirements to a standardised benchmark. The participants of the aerospace quality standards programme are issued an AS91XX certificate.

The AS/EN 91XX aerospace quality standards cover, but are not limited to:

  • Configuration management
  • Project management
  • Risk management
  • Validation of special processes
  • Counterfeit parts control
  • Control of work performed outside the supplier’s activities

AS/EN 9100

AS/EN 9100 is a quality management standard for the ASD industry published by the International Aerospace Quality Group (IAQG). The AS/EN 9100 quality standard is based on ISO 9001, adding requirements specific to the ASD segment while striving to meet the needs of stakeholders. Prior to AS/EN 9100, various corporations followed different competing quality documentation and requirements, creating challenges for the industry in terms of enforcement and compliance. The globally recognised AS/EN 9100 certification enables organisations to demonstrate their integrity and commitment towards aerospace quality management systems (AQMS). AS 9100 audit and subsequent compliance ensures consistent quality across the aerospace industry.

AS/EN 9110

The AS/EN 9110 standard pays special emphasis on the requirements critical to the maintenance of all aircrafts. In addition to the requirements present in AS/EN 9100, this standard includes additional criteria for maintenance repair and overhaul facilities for organisations (AMO / MRO) serving the industry. Some areas the AS/EN 9110 standard cover are detection and prevention of unapproved and counterfeit parts, human factors, as well as safety management systems.

AS/EN 9120

The AS/EN 9120 standard was developed for distributors and suppliers working with original equipment manufacturers (OEMs). The standard focuses on product safety and reliability, and addresses critical product performance, conformity to specifications and airworthiness. It covers the chain of custody, traceability, stock control and availability of records as well.

Why is AS/EN 91XX important?

Adopting the AS/EN 91XX quality management system allows the company to commit to a long-term goal. To achieve it, the decision-makers of the company will have several considerations, including the strategy and direction the company will take, the measures to identify and minimise risks, and compliance with the AS/EN 91XX quality management system standard.

Beyond gaining a competitive advantage and global recognition, certified suppliers achieve a significant improvement in quality and safety while reducing costs throughout the aerospace management system. They also reap benefits from the enhanced processes and achieve continual improvement.

For instance, global aeroplane manufacturers such as Boeing, Airbus, Rolls Royce, and Pratt & Whitney view the AS/EN 9100 quality management system standard for aerospace audit as a key factor when selecting and evaluating suppliers.
