The Ibis GS-501 Urraco (Magpie) is a Colombian homebuilt aircraft that was designed and produced by Ibis Aircraft of Cali, introduced in 2000. The aircraft is supplied as a complete ready-to-fly-aircraft or as a kit for amateur construction.

Design and development
The GS-501 Urraco features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cabin with vertically-hinged doors, fixed tricycle landing gear with wheel pants and a single engine in tractor configuration.

The aircraft is made from sheet aluminium "all-metal" construction, with the wing tips and cowling made from composite material. Its 9.20 m span wing employs a NACA 650-18m airfoil, mounts flaps and has a wing area of 12.97 m2. The wing is supported by V-struts and jury struts. Two wings are available, the SuperSTOL, with double slotted flaps and the Express. The main landing gear is sprung 7075-T6 aluminium, while the nose gear has lever suspension using rubber pucks and helical springs. The main wheels include hydraulic disc brakes.

The acceptable power range is 75 to 119 kW and the standard engines used are the 75 kW Rotax 912ULS and the turbocharged 86 kW Rotax 914 powerplant, driving a three-bladed Ivoprop propeller. Continental Motors, Inc. or Lycoming Engines powerplants up to 119 kW may also be fitted.

The aircraft has a typical empty weight of 340 kg and a gross weight of 600 kg, giving a useful load of 260 kg. With full fuel of 55 kg the payload for pilot, passenger and baggage is 205 kg.

The standard day, sea level, no wind, take off with a 75 kW engine is 100 m and the landing roll is 150 m.
