Who holds what
Behind every certified design, modification and piece of approved equipment is an organisation the FAA holds responsible. These are the names that appear most, each with a page gathering everything under it. Type certificate holders are listed on the certificates page; the companies approved to make replacement parts on the part makers page.
Approved modifications companies holding the most supplemental type certificates
