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 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. Further refinements produced the 180 hp (134 kW)
Lycoming O-360-A1LD powered WA-54 Atlantic. ==Variants==
