Understanding the Supplemental Type Certificate [Aviation Law]: Definition and Importance
Definition & Meaning
A supplemental type certificate (STC) is an official approval issued by an aviation authority, such as the Federal Aviation Administration (FAA), that allows for modifications to an aircraft, engine, propeller, or appliance. This certificate details the specific design changes made to the product and explains how these changes impact the original type design. Essentially, an STC is necessary when a manufacturer or operator wishes to alter a certified product in a way that deviates from its original specifications.
