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. **01** **Create Your Project**Set up a certification project, define the scope, and invite your team. Tungsten creates the structure — you focus on the engineering. **02** **Manage Documents & Tasks**Upload documents, assign review tasks, and track approvals through structured workflows. Real-time collaboration keeps everyone aligned. **03** **Review, Approve & Deliver**Take snapshots for formal review, capture approvals with audit trails, and deliver compliant documentation packages to authorities. Reports are digitally signed, saved and secured for future reference. ## Simple, transparent pricing Two clear plans, no per-seat charges, no feature gates.
