WHAT YOU WILL LEARN

What is Part 21J?

EASA Part 21J applies to design organizations that design aeronautical products, parts, or appliances and/or that define changes or repair procedures. To perform such activities, organizations must have proven their capabilities and received approval from the responsible aviation authority

Design Assurance System

Design organizations must use sustainable systems to monitor and control designs and changes. It has to be ensured in particular that the relevant regulations are complied with. Also design organizations must have structures and resources in place, allowing them to verify full compliance with certifications specifications.

Approval Requirements

Design activities may only be provided by design organizations, if sufficiently qualified personnel are available and if the required facilities are available. Beyond that, it is explicitly postulated that information is exchanged between different departments and external providers in a sustainable and coordinated matter

Transferability

As a rule, the acknowledgment as an approved design organization is not transferable to other organizations or locations, e.g., by sale or endowment

Privileges

Certified Design Organizations are entitled to perform design activities to the extent of their approval. They can categorize design classifications and approve changes that are classified as minor by themselves. These organizations are entitled to approve major repairs if they hold the certification. Operational design information and instructions can equally be issued by 21J organizations.

Obligations of the Holder

An approved 21J organization must ensure that design data comply with relevant regulations and do not pose any safety risks. Approved. Design Organizations are under obligation to provide all design documents that are not classified as "minor" to EASA for approval if requested.
