The Jurca MJ.5 Sirocco is Marcel Jurca's fifth aircraft design, and was derived from the similar but smaller low wing single seat MJ.2 Tempete, which first flew in June, 1956. First flight of the MJ.5 Sirocco took place in August, 1962. Both designs were prepared for a number of different engines of varying horsepower, and the MJ.5 is actually certified in France to FAR Part 23 standards, being static tested to +6 g and -4 g. It is aerobatic rated for two persons aboard in the tandem seating. At least one MJ.5 was factory-built in France. Jurca's Sirocco name for the aircraft refers to the hot, dusty dry strong wind from North Africa that assaults southern Europe in the spring. Construction is of wood framing sheathed in plywood skin and fabric covered wings in taildragger configuration. Tandem seating for two is under a huge blown clear canopy with marvelous visibility. The main landing gear is inward-retractable built as an alternate method on the plans. Gear down indicators are shown on the wings.
