SevinTech has well-trained and creative specialists in design and production with particular expertise on all large airplanes. SevinTech design organization performs all functions in the scope of avionic, cabin interior and structure under the DOA DO-15. Design and installation of parts and assembly, 3D CAD modelling, preparing production and installation technical drawings and production planning are some of our design services.
Cabin interior

    SevinTech provides a full suite of design and parts-supply services to reconfigure the cabin interiors of commercial and VIP aircraft. From simple LOPA changes to business class and VIP interiors, we are able to provide related approvals for design changes, as well as approved parts to protect future asset value. Our team of engineers has extensive experience in the Boeing and Airbus fleets, including the most popular narrow body aircraft, through to the popular wide body aircraft. We offer a catalogue of the most popular pre-approved LOPA configurations for cost-effective re-configurations. Our capabilities include:

    • Interior upgrades
    • Seating installation
    • Seat modification and testing
    • Emergency safety equipment installation and approval
    • Interior compartment upgrade
    • Structural component installation including overhead bins, PSU, dividers, galleys and other monuments
    • Flammability testing of cabin components (FAR/CS 25 Appendix F)
Avionic equipment installation

    Sevintech avionic team are involved in projects related to modification or addition of avionic systems in aircraft. Design and production of avionic components is performed seamlessly by our team members. Besides the current projects, research is carried out to develop inventive solutions for improving our products. SevinTech offers a wide range of solutions that take user experience to new heights, including:

    • IFE system removal/installation/adaptation (general screen, in-seat display, WIFI IFE equipment)
