Aircraft Design & Certification

Supplemental type certificates (STC)

Your certified aircraft needs a change, perhaps because you want to include modern equipment, your lighting is to be converted to LED, or you want an extra fuel tank.You might also want maintenance or service instructions alternative to those of the manufacturer.

We take care of a complete EASA certification procedure.

Supplemental type certificates can in principle be carried out for all requests:

  • Structural change
  • Change in equipment
  • Alternative Documentation (manuals, maintenance procedures and service intervals)

The supplement may apply to a single aircraft, but also to several serial numbers.

Wing/fuselage reinforcement

The outrage in the Blaník L13 community was enormous, after EASA grounded all airplanes in 2010. The cause for this drastic measure was a fatal in-flight wing rupture, whose cause was quickly identified by an FEM-analysis of the load path.

For regaining airworthiness of this Type, AD&C has developed a Supplemental Type Certificate, which improves the load path of the critical area.

Steerable tailwheel for the Schemp-Hirth Ventus cM

Being a self-launching glider, it is unfortunate the Ventus cM cannot autonomously taxi to and from the runway. To address this problem, we have developed a change giving the Ventus a steerable tail wheel and thus the autonomy it was lacking.
