TS EN 9101

TS EN 9101 is a standard focused on how audits are prepared, carried out, and reported for quality management systems in aviation, space, and defence organisations. It sets out the audit approach and the reporting content used to assess conformity with the EN 9100-series requirements, the organisation’s QMS documentation, and customer as well as statutory and regulatory requirements.

In general technical terms, an audit is not only a document check; it is a structured way to determine whether processes are implemented as intended and whether they are effective. In this context, the standard is concerned with more than compliance findings. It also addresses how those findings are recorded, how consistency is maintained, and what information should be included in audit reporting. In high-reliability sectors such as aerospace and defence, that distinction matters because process adequacy and the assurance chain for product realization must be evaluated together.

Main focus of audit reporting

• Requirements for audit preparation and execution
• Expected content and structure for reporting conformity and process effectiveness
• Linkage to EN 9100-series requirements, the organisation’s QMS documentation, and customer/statutory/regulatory requirements
• Additional or modifying provisions relative to the ISO/IEC framework for conformity assessment, auditing, and certification

This listing is based on the 2018 EN 9101 edition and has been withdrawn, but it remains a useful technical reference for understanding how audit reports are structured in the aviation, space, and defence sectors. The standard is intended to be read alongside the general ISO/IEC conformity assessment framework, and it states that EN 9101 takes precedence where there is any conflict.
