Different-powered variants include the Wassmer WA-51 Pacific,the Wassmer WA-52 Europa and the Wassmer WA-54 Atlantic. It was the world's first composite material-built aircraft. Having manufactured glass-fibre cowlings for Bébé, D112 and D120 Jodels, increasing number of glass-fibre parts for their Javelot, Bijave and Super-Javelot gliders, and then Super-IV aircraft, in 1966 Wassmer first flew the glass-fibre WA-50 prototype, a single-engined four-seat cabin monoplane with a retractable tricycle landing gear. Originally designed as a three-seater powered by a 115cv Potez engine, engine unavailability at the time resulted in a 150cv Lycoming O-320 being used instead and the aircraft becoming a 4-seater. Using the same profile as the Super-IV but only 8.6m span, and compensated with large slotted flaps, the wings were formed from two moulded halves and contained two 70 litre fuel tanks. The fuselage was also manufactured as two halves, and featured butterfly doors. The design entered production as the WA-51 Pacific (39 built) with a fixed tricycle landing gear. The low-wing cantilever monoplane was powered by a nose-mounted 150 hp (112 kW) Lycoming O-320-E2A piston engine. A variant, powered by a 160 hp (119 kW) Lycoming IO-320-B1A was called the WA-52 Europa (59 built). Further refinements produced the 180 hp (134 kW) Lycoming O-360-A1LD powered WA-54 Atlantic (55 built). The WA-53 was a proposed variant with a 125hp Lycoming engine, but was not built. Wassmer went into liquidation in 1977, Specifications below are for the WA-54 Atlantic variant.
