The Microleve ML 500 is a Brazilian ultralight aircraft that was designed by Swiss engineer Hans Gygax and produced by Microleve of Rio de Janeiro. The aircraft was supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.^[1][2]

The company appears to be out of business and the aircraft no longer available.

The ML 500 complies with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced parasol wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in pusher configuration.^[1][2]

The aircraft is made from bolted-together aluminum tubing, with its flying surfaces covered in Dacron sailcloth and the cockpit enclosure is built from fibreglass. Its 10.3 m (33.8 ft) span wing has an area of 14.7 m² (158 sq ft) and is supported by V-struts and jury struts. The tail is mounted to a small diameter aluminium tube. The standard engine available was the 64 hp (48 kW) Rotax 582 two-stroke powerplant, mounted on the wing trailing edge. The landing gear can be equipped with optional wheel pants.^[1][2]
