The CAB GY-30 Supercab was a two-seat light aircraft built in France in 1954, as a further development of the CAB Minicab. The design was performed by Yves Gardan, a onetime employee of French aeronautical company SIPA. Changes incorporated in the Supercab included a more powerful engine, greater wingspan, manually retractable undercarriage, and slotted flaps that replaced the split flaps of the Minicab.
