Minor & Major

Why do you need a design company?

find out.

All deviations from an aircraft type design are “changes” that have to be approved by the authorities. Because these deviations can range from a simple correction to a massive structural intrusion, the EASA considers two kinds of changes: minor and major changes. Major Changes are design changes as defined by EU regulation 748/2012 § 21A.91 and GM 21A.91. Minor Changes are all other changes not classified as a Major Design change.

As a Part 21J Design Organization, we are entitled to classify and approve minor changes, as well as help our customers plan for major changes. This gives us more flexibility to find solutions for your requests.

Your benefit?

our experience

The extent of our experience in Minor Changes ranges from simple Cabin carpet changes, and bilingual interior placards, to life raft replacements and the installation of satellite trackers in helicopters!

No matter your desired design concept, we will offer a tailor-made solution for you. Our wide spread Part-21J capabilities are related, but not limited, to:

  • Avionics, and their installation
  • Structure
  • Electrical systems
  • Cabin interiors
  • Galleys or other interior equipment

We welcome the opportunity to provide you with a quote for your requests, however small or large they may be. We are looking forward to be part of your individual project.
