The Jurca MJ-54 Silas is a two-seat light touring cargo aircraft designed by Marcel Jurca to enable a small car to be transported along with the pilot and passenger.

The aircraft came from an idea by Arthur-Joseph Torossian in 1992, who wanted a touring aircraft which could carry a very small vehicle, such as the Aixam Microcar, for use at remote airfields, and which could also be used as sleeping accommodation with the car removed. The car could also act as an aircraft tug at airports. He envisioned it as a combination of a Max Holste Broussard and a Transall C.160. He saw many other uses for the aircraft, including as an air ambulance, carrier for four parachutists, disabled persons carrier, or freighter. Torossian envisaged a market for 1000 aircraft, and during the development of the prototype was looking for a company to mass-produce it.

The designer of wooden homebuilt aircraft, Marcel Jurca was enlisted to design the prototype. Construction was started at Cerny Aerodrome, La Ferté-Alais by Torossian and a group of friends, who together formed a group known as the Association Tegas, a reversal of the surname of Dassault test pilot Jean-Marie Saget. This led to the aircraft sometimes mistakenly being called “The Tegas”.

The MJ-54 is a high-wing monoplane of wooden construction, with two seats accessed by two gull-wing doors. The cockpit was designed with touring comfort in mind. The fuselage is a box structure with a rear loading ramp up which a small car can be driven, or other freight loaded. The centre of gravity changes little, whether loaded or unloaded. It has a cantilever wing. The horizontal tailplane is attached to the underside of a rear boom, with twin fins and rudders on the tips. It has a fixed tricycle undercarriage.

The aircraft, registered F-WGBT and nicknamed “Cargolito”, first flew on 30 April 1997, but this may have just consisted of a few hops along the runway. Development was slow, and a public presentation wasn’t held until 16 January 2002 at La Ferté-Alais.

Apparently, obtaining a permit to fly was difficult because of the fuel in the car’s tank. Joseph Torossian had great problems getting finance for production. A planned promotional tour of French flying clubs seems not to have taken place, and little has happened to it since. It remains stored on the airfield.

Jurca Plans will provide a 75 per cent Spitfire Mk9 set of plans. The replica will be Powered by a Buick V 6 developed to produce 280 hp from the 3.8 lt capacity. The airframe, which has been professionally stress analysed be ESTACA, will allow engines of up to 700 lb. A 150 litre tank is located in the scuttle. There are no wing tanks. The cockpit fit is snug. The complex wing is true to Mitchell’s original form. Retraction is by electro hydraulic means. Flaps are fitted and have two positions. As an option, Jurca Plans will provide you fibreglass fairings.

To facilitate homebuilding replicas of fighter planes, designer Marcel Jurca has created a scaled-down ver¬sion of the P-51 Mustang, the Supermarine Spitfire and the Focke Wulf FW-190. The Mustang is available in 2/3 (MJ-7) or 3/4 scale (MJ-77). Only the relative size of a pilot’s head identifies the Baby P-51 from its bigger brother. The ship first flew with a 200-hp Ranger inline engine. Others that can be used include: any of the six-cylinder Rangers, the 125-hp Mènasco, the 130-hp Gipsy Major, the 125 to 160-hp Canadian Rambler, or the General Motors Buick F58. Materials used are wood and fabric.

The Mustang replica is of all-wood construction and uses many components from the aircraft industry. It has a retractable undercarriage and conventional flight control surfaces and flaps. The fuselage, wings and empennage are of sitka spruce framework with a plywood covering and an exterior finish of thin fiberglass. It is powered by a six-cylinder Lycoming aircraft engine.

Although capable of carrying two persons, with the second seat removed and an additional fuel tank installed, the design represents the earlier P-51B with the high rear fuselage, rather than the more common P-51D with a bubble canopy.

The two-thirds scale replica P-51B Mustang is the model MJ-7-G.

Boeve Fiberglass Components Inc offered full kits (1997) for US$35,000. Plans were selling for US$500.

The prototype MJ.5 Sirocco tandem two-seat aerobatic monoplane, built in France, was first flown in 1962. The Sirocco, an all-wood, fiberglass or fabric-covered low-wing design, can be identified by its rooster tail. The Sirocco sports retractable landing gear.

Flying with or without wing end plates, the inboard wing fence is employed in either case. The prototype flew with a Hirth engine, but 90 to 100 hp Continental or 105 hp Potez engine may be fitted. The original prototype was still flying after 30 years.
