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.Purdy, Don: AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition, page 207. BAI Communications, 15 July 1998. {{ISBN|0-9636409-4-1}}
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 {{convert|10.30|m|ft|1|abbr=on}} span wing mounts flaps and has a wing area of {{convert|16.48|m2|sqft|abbr=on}}. The wing is supported by "V" struts, jury struts and cabane struts. The acceptable power range is {{convert|50|to|74|hp|kW|0|abbr=on}} and the standard engines used are the {{convert|50|hp|kW|0|abbr=on}} Rotax 503, {{convert|64|hp|kW|0|abbr=on}} Rotax 582 or the {{convert|74|hp|kW|0|abbr=on}} Rotax 618 powerplant.
The aircraft has a typical empty weight of {{convert|220|kg|lb|abbr=on}} and a gross weight of {{convert|445|kg|lb|abbr=on}}, giving a useful load of {{convert|225|kg|lb|abbr=on}}. With full fuel of {{convert|64|L}} the payload for the pilot, passenger and baggage is {{convert|179|kg|lb|abbr=on}}.
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.{{cite web|url = http://registry.faa.gov/aircraftinquiry/AcftRef_Results.aspx?Mfrtxt=&Modeltxt=ML+450&PageNo=1|title = Make / Model Inquiry Results|accessdate = 15 January 2014|last = Federal Aviation Administration|date = 15 January 2014}}
