Below is an overview of our company’s structure:

ASF Engineering GmbH - We are working in the aviation industry

Since 2008, our company has been serving the civil aviation and military defense industries.
Together with partners who are certified developers and manufacturers for the aviation industry, we design, produce, and supply insulation, custom-engineered components, and interior trim.
The necessary soundproofing and acoustic tests are conducted in our testing facilities.

Since 2015, we have also been operating as an EASA Part 145 maintenance organization for aircraft seat belts, restraint systems, and cargo nets – see ASF SafetyBelts.

Since 2021, we have expanded the scope of our maintenance operations to include the maintenance of rescue and safety equipment such as life jackets and cargo nets – see R&S Aircraft Service.

By obtaining the approved development organization approval under EASA Part 21J, we are able to perform work covered by EASA Form 1 – see HOSA.
