Microleve ML 450

The Microleve ML 450 (sometimes ML450) is a Brazilian microlight aircraft that was designed and produced by Microleve of Rio de Janeiro. When it was available the aircraft was supplied as a complete ready-to-fly-aircraft or as a kit for amateur construction.

Design and development
The aircraft features a strut-braced parasol wing, a two-seats-in-side-by-side configuration open or optionally enclosed cockpit, cruciform tail, fixed tricycle landing gear with wheel pants and a small tail skid, and a single engine in pusher configuration.

The aircraft is made from aluminum tubing and composites, with its flying surfaces covered in doped aircraft fabric. Its 10.30 m span wing mounts flaps and has a wing area of 16.48 m2. The wing is supported by "V" struts, jury struts and cabane struts. The acceptable power range is 50 to 74 hp and the standard engines used are the 50 hp Rotax 503, 64 hp Rotax 582 or the 74 hp Rotax 618 powerplant.

The aircraft has a typical empty weight of 220 kg and a gross weight of 445 kg, giving a useful load of 225 kg. With full fuel of 64 L the payload for the pilot, passenger and baggage is 179 kg.

The manufacturer estimated the construction time from the supplied kit as 250 hours.

Operational history
By 1998 the company reported that 250 aircraft were completed and flying.

Even though the aircraft was marketed in the United States, by January 2014 no examples were registered with the Federal Aviation Administration.
