TS EN 9131
Aerospace series - Quality Management Systems - Nonconformance Data Definition and Documentation
1.1 Application This standard defines the common nonconformity data definition and documentation that shall be exchanged between an internal/external supplier or sub-tier supplier, and the customer when informing about a nonconformity requiring formal decision. The requirements are applicable, partly or totally, when reporting a product nonconformity to the owner or operator, as user of the end item (e.g., engine, aircraft, spacecraft, helicopter), if specified by contract. Reporting of nonconformity data, either electronically or conventionally on paper, is subject to the terms and conditions of the contract. This also includes, where applicable, data access under export control regulations. 1.2 Purpose The process of exchanging, coordinating, and approving nonconformity data via concession or product quality escape varies with the multiple relationships and agreements among all parties concerned. The information provided by this standard forms architecture for submitting and managing data that allows for concise and accurate communication using various documented methods. The main objective of this standard is to provide the definition of a data set that can be integrated into any form of communication (e.g., electronic data interchange, submission of conventional paper forms).

About This Item
TS EN 9131 is an aerospace quality management standard focused on how nonconformance data is defined and documented. It sets out a common data structure to be exchanged between suppliers, sub-tier suppliers, and customers when a nonconformance requires a formal decision, helping the same issue be described consistently across organizations.
At its core, the standard is about making nonconformance information interoperable, not merely complete. Whether the exchange takes place through electronic data interchange or paper-based forms, the required information elements are organized so that reporting remains concise, accurate, and comparable. This supports decision-making in supply chains where multiple parties may need to review the same quality event.
How nonconformance data is used in aerospace communication
In general technical terms, a nonconformance is any departure of a product, part, or delivery from specified requirements. In aerospace and related fields, such records are important not only for quality control but also for acceptance, concession handling, approval, and traceability. TS EN 9131 does not define the nonconformance process itself; it standardizes the communication architecture and the data set used to report it.
The standard also addresses reporting of product nonconformance to the owner or operator of the end item, where applicable and when specified by contract. Its framework applies to both electronic and conventional paper documentation, and it acknowledges that access to data may be subject to export control regulations. This makes the exchange of technical quality information more manageable across different contractual relationships.
- Creates a shared nonconformance data definition between supplier and customer.
- Supports consistent documentation when a formal decision is required.
- Can be applied to electronic interchange or paper-based reporting.
- May extend to reports sent to the end-item owner or operator when contractually specified.
- Accommodates contractual terms and export-control-related access conditions.
