With 164+ EASA-approved modifications across 9+ countries, we deliver mission-ready solutions for air ambulance, law enforcement, border surveillance, search and rescue, and utility operations. From surveillance to medical and navigation upgrades, our certified solutions are tailored to each mission.

DESIGN, PRODUCTION AND INSTALLATION UNDER ONE ROOF

We hold three EASA approvals: Part-21 Design, Part-21 Production and Part-145 Maintenance. That means the approved design, the finished part and the installation can all come from us, whether you arrive with a requirement, a concept or a complete design.

See our Part-21 Production →

WHAT THIS MEANS IN PRACTICE

  • One point of contact, from operational requirement to installed hardware
  • Producibility built into the design before it is frozen
  • Prototype findings go back into the same approved data, not a parallel set
  • Parts supplied with an EASA Form 1
  • Static structural testing and on-aircraft EMI testing in house, with DO-160 qualification, flammability, shock and vibration at accredited test facilities
