Consequently, changes to OSD are handled in accordance with Part-21 procedures in the same way that e.g. “ICA (STC)”, 21A.449 “ICA (Repair)”, 21A.609 “Obligations of holders of ETSO authorisations” CS 22.1529 CS 23.1529, CS 25.1529*, CS 27.1529, CS 29.1529, CS 31HB.82*, CS-E 25, CS-P 40, CS-APU 30, CS- VLA 1529, CS-VLR 1529 and their related Appendices, AMC material and other requirements (Part M and 145) Approve minor changes, or for approval of identical replacement parts, unless the installation of such parts constitutes a major change to the type design. There are two types of DARs: manufacturing, and maintenance. A major change to the design of a type-certificated product is approved by a separate process and issued on a supplemental type certificate or an amended type certificate. This CVE can be external (for instance located within the flammability lab), in which case, the person must be linked to the DOA, being FAA DER or not.

Most DARs have limited and/or certain “functions” authorized by the FAA based on their experience and technical background. Manufacturers or applicants outside of the U.S., except as provided for in a bilateral agreement. Chances are the STC holder also has FAA manufacturing approval to make the part or has given the manufacturer use a PMA assist so they could get FAA MIDO approval to make that monitor, installation kit, and as a result it's an airplane part.

The ACO must provide a covering letter endorsing and classifying the application (Basic or non-Basic) and forward it to EASA. A one-only STC cannot be amended and the holder is not eligible for production approval. For example, in the case of STCs issued by the FAA, in accordance with the Technical Implementation Procedure (TIP) between the FAA and EASA, the FAA STC holder must make the application via the FAA Aircraft Certification Office (ACO) that issued the original approval. (To also consider the potential affect on the Maintenance Program – MSG 3 Analysis may be required to develop additional maintenance obligations). All documents used by the DOA holder to demonstrate compliance must be signed off by a CVE of the DOA holder. A supplemental type certificate holder who allows a person to use the supplemental type certificate to alter an aircraft, aircraft engine, or propeller must provide that person with written permission acceptable to the FAA. DARs work within their geographic region, a geographic expansion maybe obtained however starting in 2015 some of these expansion request have been denied due to national policy changes.

If the approved modification affects the operating characteristics of the aircraft in which it is installed, then changes to the performance procedures and any operating limitations required are issued as a supplement to the original type-certified AFM and this is part of the STC. It is essentially unlimited in the scope of the modification. STC embraces responsibility for its actions towards the community and actively seeks channels to impose positive impact on the environment and stakeholders including consumers, employees, investors, communities, and others. It defines the product design change, states how the modification affects the existing type design, and lists serial number effectivity.

The STC holder has also determined that the cargo barriers have insufficient structural strength if subjected to emergency landing loads with the cargo load weights listed in the existing airplane flight manual (AFM) supplements. An STC which modifies a TSO article must provide for installation, Combine two or more STCs without additional showing of compliance; or. A Supplemental Type Certificate (STC) is a type certificate (TC) issued when an applicant has received FAA approval to modify an aeronautical product from its original design. Designated Engineering Representatives (DER) – Engineering and Flight Test designees are responsible for finding that engineering data complies with the appropriate airworthiness standards.
