The resultant design, the Gavilán, is a simple high-winged monoplane of all-metal construction. It has a boxlike, square-section fuselage that accommodates a pilot and up to seven passengers, with access through two doors on either side of the cockpit and a large cargo door on the left side of the fuselage. The passenger seats can be removed to allow carriage of cargo, including a full-sized coffin. It is fitted with a fixed tricycle undercarriage designed to withstand continued operations from rough South American airstrips. It is powered by a 350 hp (261 kW) Lycoming TIO-540-W2A engine, turbocharged to give sufficient power at Colombia's high altitudes.
