STE Maintenance Group

Born in 1983, long before digital transformation was a buzzword, the group originally set out to solve a simple but critical challenge: How can we make technical English clear, consistent, and safe – for everyone, everywhere?

Clear language isn't just a writing choice. It's a strategic advantage. The answer became the first edition of the AECMA Simplified English Guide (AECMA was the predecessor of ASD). When ASD was formed in 2004, the group evolved into STEMG and continued its mission – now maintaining what is globally known as the ASD-STE100 Simplified Technical English standard.

In safety-critical industries, every word counts. Poorly written instructions can lead to mistakes, downtime, or even accidents. The STEMG exists to prevent that – by making sure every edition of ASD-STE100 is useful, usable, and trusted by professionals worldwide.

What does the STEMG actually do?

• Keeps the STE standard relevant: new words, new technologies, new challenges – STEMG reviews and updates the rules accordingly.
• Processes user change requests: the community helps improve the standard – and STEMG ensures quality and consistency.
• Supports industries beyond aerospace: from aviation to medical devices, rail to software – STE develops and maintains ASD-STE100 up to date and up to needs from diverse sectors write with clarity.
• Aligns with ASD policy and governance: every update is done with precision and accountability.
