ST Aerospace has been granted two Supplemental Type Certificates (STCs) for its Boeing 757-200SF passenger-to-freighter (PTF) conversion programme from the Civil Aviation Administration of China (CAAC) and Transport Canada respectively.
The STCs allow ST Aerospace to incorporate major engineering changes and convert a China-registered or Canada-registered 757-200 aircraft from a passenger-carrying configuration to a cargo aircraft.
ST Aerospace’s FAA approved 757-200 PTF STC is the world’s only STC developed based on Boeing’s licensed passenger and freighter data.
