As anyone in this industry knows, the difference between a compliant aircraft part and a questionable one often hinges on traceability. Knowing exactly what kind of approval stands behind a component – and being confident in its journey from production to point of installation – has never been more important.

With global fleets returning to full utilisation and supply chains still under strain, the spotlight is firmly back on what makes a part truly ‘approved’. It’s not always a straightforward question – and that’s why this issue’s cover feature from Jason Dickstein at the Washington Aviation Group is such a valuable read. Jason offers a clear, practical breakdown of the US parts approval system, covering everything from PMA and TSOA to production certificate parts. Even for those well‑versed in the subject, it’s a timely refresher.
