The EASA approved Part 21J Design Organisation in DAO is your starting point for any request regarding certification of design changes in the aviation business or military/state air operations. Regardless of which type of aircraft or rotorcraft your inquiry applies to our experienced design team is ready to assist you with safe and reliable technical solutions for your unique needs. To gain a full overview of the requested subject, our team will develop a technical proposal, containing the most important details about the project. For planning purposes, we will estimate timeline for all certification processes, from design, implementation, compliance showing, to the final approval of the design change.
