The Jurca MJ-5 Sirocco (named for the Sirocco wind) is a two-seat sport aircraft designed in France in the early 1960s and marketed for homebuilding.[1] It is one of many wooden homebuilt designs from Romainian born designer Marcel Jurca. Jurca, a Henschel Hs 129 pilot in World War II marketed the plans in Canada and America through Falconar Aviation.[2] It is a low-wing cantilever monoplane of conventional configuration and wooden construction throughout.[3] The tandem seats are enclosed by a bubble canopy, and the tailwheel undercarriage can be built as either fixed or with retractable main units. Marcel Jurca died on 19 October 2001, at which time plans were still available from the designer's web site.
