A Supplemental Type Certificate (STC) is a regulatory approval issued by aviation authorities, such as the FAA in the United States, which allows for the modification of a type-certificated aircraft, engine, or propeller. It is used to demonstrate that a change to the original type design meets safety and airworthiness standards.
Any manufacturer, developer, or entity that intends to modify a type-certificated aircraft, engine, or propeller must file for a Supplemental Type Certificate. This includes companies that create alterations or additions to the original design.
To fill out an STC, one must complete the specific application forms provided by the respective aviation authority, provide all required documentation and technical data that supports the modification, and demonstrate compliance with applicable regulations. It typically involves a comprehensive submission that includes plans, specifications, and testing results.
The purpose of a Supplemental Type Certificate is to ensure that modifications made to an aircraft, engine, or propeller do not adversely affect safety or airworthiness. It provides regulatory validation that the new features or changes meet all necessary standards.
Information that must be reported on an STC includes the applicant's details, the aircraft or component being modified, description of the modification, compliance with pertinent regulations, testing data, and any other documentation that substantiates the design change and its impact on safety and performance.
