A supplemental type certificate (STC) in the United States is an FAA approved major modification or repair to an existing type certified aircraft, engine or propeller. The purpose of the STC process is to ensure the modified or repaired item remains airworthy in accordance with the approved standards and requirements of the original type certificate. Many other countries use the STC process, however, the regulator is not the FAA but the analogous agency in that country. As it adds to the existing type
certificate, it is deemed “supplemental”.
