In June 2020, Duncan Aviation announced that it had partnered with Gogo Business Aviation to provide new installation options for the Gogo AVANCE L3 and the Gogo AVANCE Smart Cabin System (SCS). The Engineering & Certification Services teams at Duncan Aviation updated three existing Supplemental Type Certificates (STCs) for the Gogo AVANCE L5 Wi-Fi system so customers will be able to use those STCs to install the AVANCE L3 Wi-Fi system or a standalone SCS on the following aircraft:
- Gulfstream GIV and GIV-X
- Bombardier Challenger 300 and 350
- Bombardier Challenger CL-650, CL-605, CL-604, CL-601-3A and CL-601-3R
