How long does it take to get started with Tungsten?

Most design offices are up and running within a day. Create your organisation, invite your team, and start your first project. No complex integrations or IT involvement required.

Is my certification data secure?

Absolutely. Tungsten is hosted on AWS infrastructure with encryption at rest and in transit, automated backups, and role-based access controls. Your certification data is housed in European data centres.

Can we bring in existing projects?

Yes. You can create and continue managing projects that are already underway. Tungsten is designed to slot into your existing workflow, not replace it from scratch.

Will Tungsten work for Part 21G (Production) as well?

Tungsten is purpose-built for Part 21J Design Organisations. While some concepts overlap with Part 21G, our workflows, document templates, and approval chains are specifically tailored to the design office certification process.

What if our current compliance process already works?

Good — Tungsten isn't here to tear that up. It digitises and structures the process you already follow, eliminating manual bottlenecks while preserving your established workflows and professional judgment.

How much does Tungsten cost?

Tungsten offers two plans: £500/month for Design Office and £1,000/month for Enterprise, both billed annually. Both include unlimited users and projects, and include a 3-month money-back guarantee.

Still drowning in the paperwork labyrinth?

If any of this sounds familiar, you're not alone. Most Part 21J offices are still fighting the same battles.

Printing, signing, scanning — repeat

Endless cycles of printing documents for wet signatures, scanning them back in, and hoping nothing got missed along the way.

That sinking feeling on page 87

One misplaced reference, one wrong revision number — and the whole submission gets bounced. Hours of rework for a preventable mistake.

Your best hours, wasted

Airworthiness engineers with years of specialist knowledge, spending their days reformatting spreadsheets and chasing signatures instead of engineering.

Designed for Part 21J Design Offices

Tungsten isn't another system to learn — it's purpose-built for the regulatory landscape your team navigates every day. Structured compliance without rigid tools getting in the way.

Streamlined
Standardise and automate the repetitive data collation process. Step by step processes guide you through the certification maze to produce high quality data packages ready for submission.
Flexible
Use Tungsten on the go — create a project while surveying the aircraft. Web-based and platform independent, it runs equally well on any modern browser, tablet or mobile device.
Rewarding
A highly structured method for creating and storing project data allows you to benefit from submissions that are easy to read, more compliant, and lead to a trustworthy certification system.

Everything your design office needs

Individually written reports and repetitive data collation can lead to incoherent and untrustworthy submissions. Tungsten replaces spreadsheets, shared drives, and disconnected tools with one purpose-built platform.

Document Management
Version-controlled documents with structured approval workflows. Upload, review, approve, and publish — all in one place.
Snapshot Reviews
Capture project state at any point for formal review. Compare snapshots to track progress and ensure nothing was missed.
Task Tracking
Assign certification tasks to team members with deadlines, priorities, and status tracking. Never lose sight of what needs doing.
Activity Logs
Every action is recorded in an organisation-scoped audit trail. Know who did what, when, and on which project.
Role-Based Access
Fine-grained permissions ensure engineers see what they need and approvers control what they should. Configurable per organisation.
Powerful Search
Search by type of project, classification, or keyword descriptions. Project data can be entered or reviewed in multiple ways, giving you complete flexibility and control.

The engineer's shortcut to EASA compliance

Tungsten replaces the chaos with a clear, structured path from project creation to authority submission.
