This course addresses the critical issue of Suspected Unapproved Parts (SUPs) in aviation, a topic that directly impacts safety, compliance, and trust within the industry. It introduces engineers and maintenance staff to the risks posed by unapproved or counterfeit parts and explains how to recognise, report, and prevent their use in aircraft maintenance.

The training begins with the regulatory background, exploring EASA, FAA, and ICAO requirements that set the framework for identifying and controlling unapproved parts. You’ll learn why SUPs are such a serious concern for continuing airworthiness and how regulators, manufacturers, and operators collaborate to safeguard the system.

You’ll then explore practical examples of SUP cases, learning how these parts are introduced into the supply chain, what red flags to watch for, and the consequences when they go undetected. Real-world case studies show how unapproved parts have compromised safety and demonstrate the importance of vigilance at every stage.

The course also provides clear guidance on roles and responsibilities, including what is expected of certifying staff, stores personnel, CAMO staff, and managers. You’ll see how reporting systems work, how to escalate concerns, and how to ensure traceability and documentation protect your organisation from risk.

By the end, participants will understand not only the regulatory and technical requirements, but also the practical steps they can take in daily work to help prevent SUPs from entering service. This knowledge empowers engineers to actively contribute to safer, more reliable operations and protects both aircraft and passengers.
